Insert such a crimp type F connector and cable into some useless piece of equipment with a type F jack. Pull on the cable hard. In my experience, it doesn't take much to make the cable and connector part ways. Repeat with a screw on connector. Now, repeat the experiment using a properly assembled compression type F connector and cable. It takes considerably more brute force to break the connection. I think the official minimum pull test is 55 lbs, but I'm too lazy to Google for it now. Hiding the workmanship under shrink tube is not very functional. It will have little effect on the pull test. Most of the cable leakage problems I've seen (and found) were due to crimp type F connectors coming apart or badly crimped. That includes both the hex shaped crimp, and ones held together with a crimped ring.

If their company cable box doesn't deliver a useful and reliable signal I call that screwed up. One pays for a service and expects to either get it delivered as promised or money back. ... If they are delivering the level called for in their franchise, they didn't screw up. It has always been up to the customer to pay for or provide extra equipment for non standard installs. Mike's install does not sound non-standard. 170ft cable drop towards premises which is fairly normal, plus the cable company's set-top box. Grow up. That is an excessive length drop. A standard drop is under 100 feet. You think you know everything, and that the world has to live by your rules. You don't, and it doesn't. ... http://www.starvision.tv/lineup_res.htm Quote "Maximum Drop Length 300 Feet" Now that's what I call good service. ... I'll bet you've never even seen a CATV franchise, or the dozen of pages of specifications agreed to by both the CATV company and the local government. The CATV company isn't a Santa Clause machine, and local governments know why there are limits to the service provided. If there were't, no one could afford to build or operate a CATV system. You've never designed a headend, or a physical plant If they build to supply higher port levels, it has to start at the headend, and requires closer spaced trunk amplifers. The system noise goes up from all of the cascaded amplifers, and the equipment runs hotter, withj a very reduced service life. When you can design an RF distribution system of more than 500 MHz bandwidth and has over 10,000 output ports, with the gain stabilized to a couple dBmv 20 miles from the headend and over a range from sub zero F to + 100 F then you can tell me I'm wrong. One headend I designed and built was only off by .1 dBmv at the test port on the first trunk amp which was a half mile from the head end. If you can do better than that, I'll listen to you and your opinions See above. Obviously others can. And yes, I have designed RF broadband power amps. Lots of them. Not just lashing up boxes but the actual transistor level circuitry including layout guidance for the nasty stuff. Fact is, if a cable company isn't competent to do a 170ft drop they should decline the job. Otherwise it is a screw-up, plain and simple. In our area they'd lose their shirts to the satellite guys because there are many houses like ours where there is no reasonable way to get from the street to the house with a 100ft limit. We have around 200ft that's still there from the early 90's and the previous owner said cable TV worked just fine for them. We are not subscribed because TV ain't that important to us. -- Regards, Joerg http://www.analogconsultants.com/ |

Recently our cable company switched to the wonderful world of Digital TV. You have been assimilated. Resistance is futile. I got the new digital converter and had no picture. Something is wrong. The nominal signal from the cable drop is suppose to be 0dBm. If there's a splitter involved, they like to crank it up to about 10dBm. Your 200ft of RG6a/u will drop the signal from between 4dB at the low end, to about 6dB at the high end. Your set top box is suppose to operate with a 10dB margin. If you would kindly disclose the maker and model, it might be possible to find the specs. Typically, you'll have at least 10dB margin. Even with 200ft of coax, you should have 4 to 6dB margin.

Can you put rough numbers around what you mentioned? Like what are providers legally required to deliver at the far end of the drop? We were required to deliver 0 dBmv at the end of 100 feet of RG-59 or RG-6 for two sets per the franchise. The system was designed at +10 dBmv at the tap to allow for three or four TVs at the 100 foot range. That was on a 36 channel system with RCA modulators& HST. It was done for two reasons. To have a little extra signal available when the system was built, and for conversion for a 300 MHz plant to a 450 MHz plant without respacing the trunk amplifiers. I build a headend& interface to tie two incompatible community loops together. Ours was a sub split loop, and the other CATV company used mid split. We used 2& 12 for pilots, so we fed them Channel 2 into their return, and down converted their feed to T-9 for our return. That headend had two RCA HSP and a combiner. The interface was another HSP in a large stainless steel NEMA box mounted to a power pole at the boundary of the two systems. A pair of two way splitters were used to route the signals between the systems, as well as into and out of the HSP. The other company wanted us to install a modulator and a demodulator at the boundary to give us audio& video, and another pair from our side so the interface would be baseband. Their design was over $15,000 in hardware alone. My design was under $3000 for all the hardware& labor to install. I had system designers from both sides telling me it wouldn't work, but it did the job with no problems. :) Very nice. We were much more constrained on the install I mentioned up the thread a ways. The fiber was fed at E1 speed, which probably didn't work it very hard. We had an issue at one point. This was a distributed proc/data system, one of the first. Each cabinet was a standalone PBX. And you could make 126 of them look like one. And each could survive on its own. First fiber campus we'd done. Staggered cut to the new infrastructure. Fun stuff. At one point we had to do the cutover to the other large pice of the system. Each end connected the fiber. 0 signal. TDR from A end showed 700 meters from A end, 800 meters from end B. Length from A to B is 1500 meters. The work that occurred because of that was not fun. Had to go get the guy doing fusion splicing. Joy. Midnight trip to Pittsburgh with the salesman. Actually it was fun. Not much traffic at night. Landing pattern at 160mph in between DC9s into Pittsburgh at about midnight. And they didn't like 160 at all. This was scary. Quickest turnoff onto a taxiway I've ever experienced. Of course the taxiway may not have been one. We didn't care. Still easier than having to use blasting caps to find the ends of a broken conduit under the finished concrete floor in a new RADAR site. An old fish tape & blasting cap pushed as far as it would go and BOOM!!!. Then repeat for the other end. Then they used a jackhammer to break out the concrete between the huge floor divots to install new conduit. The electrical contractor had failed to tie the conduit to the rebar & wire mesh before the pour. :) Or driving ground rods through permafrost in Alaska. We drove 60' of rod and used three tanks of Acetylene to heat the rod to get it through the ice layer outside a military radio & TV station at Ft.

So now I suspect a weak signal and confirm that it is the cable length. The cable company came out and gave me a better cable than I had installed. At this point I have a picture but it is intermittent. The signal at the utility post has 3 outputs and had a four way splitter, I suggested the cable guy put in two 2 way splitters and give me the stronger (first) tap. That got my signal to work almost all the time. I'd like to get the signal to work 100% of the time. Looks like the cable guys screwed up. In your opinion. If their company cable box doesn't deliver a useful and reliable signal I call that screwed up. One pays for a service and expects to either get it delivered as promised or money back. ... If they are delivering the level called for in their franchise, they didn't screw up. It has always been up to the customer to pay for or provide extra equipment for non standard installs. Mike's install does not sound non-standard. 170ft cable drop towards premises which is fairly normal, plus the cable company's set-top box. Grow up. That is an excessive length drop. A standard drop is under 100 feet. You think you know everything, and that the world has to live by your rules. You don't, and it doesn't. ... http://www.starvision.tv/lineup_res.htm Quote "Maximum Drop Length 300 Feet" Now that's what I call good service. ... I'll bet you've never even seen a CATV franchise, or the dozen of pages of specifications agreed to by both the CATV company and the local government. The CATV company isn't a Santa Clause machine, and local governments know why there are limits to the service provided. If there were't, no one could afford to build or operate a CATV system. You've never designed a headend, or a physical plant If they build to supply higher port levels, it has to start at the headend, and requires closer spaced trunk amplifers. The system noise goes up from all of the cascaded amplifers, and the equipment runs hotter, withj a very reduced service life. When you can design an RF distribution system of more than 500 MHz bandwidth and has over 10,000 output ports, with the gain stabilized to a couple dBmv 20 miles from the headend and over a range from sub zero F to + 100 F then you can tell me I'm wrong. One headend I designed and built was only off by .1 dBmv at the test port on the first trunk amp which was a half mile from the head end. If you can do better than that, I'll listen to you and your opinions See above. Obviously others can. And yes, I have designed RF broadband power amps. Lots of them. Not just lashing up boxes but the actual transistor level circuitry including layout guidance for the nasty stuff. Fact is, if a cable company isn't competent to do a 170ft drop they should decline the job. Otherwise it is a screw-up, plain and simple. In our area they'd lose their shirts to the satellite guys because there are many houses like ours where there is no reasonable way to get from the street to the house with a 100ft limit. We have around 200ft that's still there from the early 90's and the previous owner said cable TV worked just fine for them. We are not subscribed because TV ain't that important to us. Yawn. You constantly harp about having to meet specs in medical, but whine like a drunken jackass when other businesses have to meet their specs. yes, they could design the sytems to 300 feet or more, but the cost to every customer on the system would go up. Would you like to pay an extra 20% to 30% just so a very few locations can get better service? Oh, that's right. You're too cheap to even have cable TV. -- You can't have a sense of humor, if you have no sense. |

Suprisingly the ones I found that worked best were the ultra cheap ones that only took a pair of pliers to fasten These were the ones with the separate crimp rings. Used with some good quality heat shrink tubing this eliminated most of the problems you mention. I dont know why these connectors went away, my only guess is that someone wasn't making enough money on them. Those were the lowest grade, next to screw on fittings. They had the highest leakage, and shortest service life of all the connectors I ever tested. Did I mention that we bought 50,000 feet of RG-59 & RG-6 per month for cable installs? We were using the Raychem for new work & repairs in the mid '80s. They were the best we could find, both for drop, trunk & feeders. They didn't need a boot, and you would break the cable before a connector would pull off, if installed properly. We had to keep a close eye on radiation to prevent one of the midband channels from interfering with airplanes. 95% of the problems were those half assed separate ring, three cent connectors. -- You can't have a sense of humor, if you have no sense. |

I'll guess(tm) that TDC is downstream power, and RDC is upstream power. (20MHz is in the frequency range used by upstream path). 30dBmV is acceptable as the upper limit is about 55dBmv. Remember, this is dB's above 1mv into 75 ohms, not dB's above 1mw into 50 ohms. dBm = dBmV - 48dB So, your 30dBmv is really -18dBm The downstream values are also in the ballpark. See: http://www.dslreports.com/faq/16085 The numbers are for cable modems, but the levels should be similar for DTV. The typical delivered values should be: -10 dBmV to +10 dBmV "Recommended". -11 dBmV to -14 dBmv / +11 dBmV to +14 dBmV "Acceptable". -15 dBmV & +15 dBmV "Maximum". 5dBmV is fairly is good enough and should result in a usable picture. See if you can excavate the SNR numbers.

NOT! now that you mention it, and is trying to compensate for his lack of success and low IQ with insults. I did more in the last week to make the world a better place than you will in your entire pathetic life, boy. Usenet. You gotta love the kooks. Go back to the kook group, you retarded ****. You will never be loved, because you are too retarded to even know what love is. tom K0TAR A complete and utter retard. He really likes the word "retard". Wonder why? tom K0TAR |

Increasing Cable TV signal strength

Yawn. You constantly harp about having to meet specs in medical, but whine like a drunken jackass when other businesses have to meet their specs. yes, they could design the sytems to 300 feet or more, but the cost to every customer on the system would go up. Would you like to pay an extra 20% to 30% just so a very few locations can get better service? Oh, that's right. You're too cheap to even have cable TV. Respectfully, Michael even though we wouldn't *want* to make a 170 foot drop. it isn't unheard of. And the amplifiers are very capable of handling it. Ind it is very location specific. Getting a decent signal at a marginal location doesn't have any effect on the rest of the system. There are attenuators and there are equalized attenuators that will give a flat signal at the end of a 170 foot drop. RG6 cable has a loss of around 5 db per 100 feet at 500 MHz. Let's give you 10 db at 170 feet, worst case. When I worked in the industry, I plugged (or designed in) in a number of equalized attenuators. It only affected a single drop, or some times a few. You could have a specific amp running about +10db, and with the equalized attenuator, hit the house around 0, flat. While some might think that it is bad design, ask the system owners whether they would want to put in another pole, perhaps with a distribution amp, or simply use a 20 dollar attenuator. The world is not perfect, and my job in the catv world included just about every part, from strand mapping to system layout to in the field work. We needed a balance between perfect and affordable. But the only time there might be an issue was if the system was over-amped, then there could be problems with proof of performance certification. We never had an issue with that. Bottom line is, a 170 foot drop is perfectly capable of having a nice flat swept signal - and it should, unless the system design itself was bad. Done properly, any issues will be mechanical rather than electrical. But nowadays they have messengered cable, so it's even less likely. - 73 de Mike N3LI - |
