wrote in : "Frank Gilliland" wrote in message .. . Mailbox is empty. Did you remove the "nospam"? I did. In fact I just sent it again just now. It does have a file attached so if your E-mail program filters out mail with attachments you will have to turn it off. I got the file with the pics. Nice work, and I'm glad to see your acceptance of the fact that solid dielectrics (even teflon) have dielectric constants that aren't constant with frequency. However, your description of a UHF-type connector isn't particularly accurate. If you had ever taken one apart you would have noticed that only a small part of the conductor (maybe a mm or two) is actually contacting the insulator. The rest is surrounded by an air gap, making most of the coupled connection a section of coax using an insulator with a dielectric constant of 1. Regardless, I suggested that you -measure- this apparent loss, not calculate it (.....gee, seems I've said that before.....). Since you don't care to measure things, I did. The Adler I mentioned earlier is a 100-watt translator tuned for TV channel 77. I measured the output to my wattmeter through one 12' length of RG-11 and again through two 6' lengths of RG-11, the difference being that the latter adds a male and female UHF-type connector to the line. The wattmeter showed no visible difference. So I did the same test directly to the dummy load and measured with an RF voltmeter at the dummy load. The difference was a loss of 0.4 volts, which is slightly less than 1 watt, or about 0.05 dB. Yes, I use teflon connectors and I keep them clean. And no, the coax wasn't overheated during soldering (it's all about the technique!). Feel free to repeat my tests, both for the UHF-type connectors and for the mag-mounts. Just don't feed me any more calculations cause they don't mean squat when the facts show something different. while impedance will "unnecessarily complicate things" for mag-mounts. You have "unnecessarily complicate things" because you don't understand the difference. Now that's an interesting answer..... the difference between impedance and capacitance is that I don't understand the difference? You haven't impressed me with knowing the difference. It was intended to educate, not to impress. I was addressing a capacitance measurement only, exclusively and separate from any other electrical property. You can't seem to figure out that your impedance measurement combines capacitance, inductance, and resistance all together. Yes it does! That's the point! Capacitance, "exclusively and separate from any other electrical property", is academic and has no practical value! If I took a 1000pf vacuum capacitor and connected it in series with a 1000 ohm resistor, placed it in a black box you can't open, and brought out two leads for you to connect to your Z-bridge then asked you to make your measurement you would tell me I have a crappy capacitor. Not at all. You can tell if the reactance is linear simply by changing the frequency feeding your impedance bridge. If it's linear then the capacitor is fine and you simply have 1k ohms of series resistance. If it's not linear then you might have a problem (depending on the intended application of this 'black box'). Then if I wanted to give you somthing to think about I can stick a small inductor in series with the capacitor and resistor to give some strange impedance variations with frequency. Now try to figure out what's in the box from your Z-bridge measurement. Just swing the signal generator up from zero until you dip, just like you would with a GDO. That's your resistance. If it peaks instead of dipping then your reactances are in parallel and you must measure resistance at DC. Then detune to measure reactances. And at this point I need to make a point: What I just described is a quick summary of the basic operation of a simple impedance bridge. The impedance bridge is one of the most fundamental yet most useful tools in radio. Now you claim to have a degree -and- you are a ham. For you to even suggest that one can't determine the properties of an unknown impedance network using an impedance bridge tells me that you have never used one, or at least not more than once or twice. If you -do- have a degree then either it isn't in electronics, you missed a lot of labs, or the school was criminally negligent in it's course of study. Either way, here's a few links to get you going: http://www.tpub.com/content/neets/14...s/14193_89.htm ftp://bama.sbc.edu/downloads/heath/am1/ ftp://bama.sbc.edu/downloads/knight/z-brdg/ And here's a fascinating page on the dielectric properties of organic tissue that also includes instructions for an impedance bridge. Note the problems with electrode polarization at low frequencies when measuring lossy dielectrics (iow, maybe you should take a second look at your low-frequency DMM method of measuring a capacitor having a dielectric of epoxy or paint): http://safeemf.iroe.fi.cnr.it/docs/H...K/chp4-2-1.htm That's the problem you have with your measurements where the black box is the mag-mount. Making a capacitance measurenet, or some simple calculations, would be like peeking inside the black box and saying, Oh now I see what is going on. Here's another "black box" scenario: Using the capacitance tester on your DMM, measure the "pure" capacitance between two high impedance windings of a power or audio transformer. I can tell you right now that your measurement will be wrong, and you can't tell what's in the "box" unless you change the frequency. Same deal for the mag-mount. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

It was a comment you made in a posted reply to Lancer. I have never said "they don't work at UHF", those are your words not mine. They are NOT RECOMMENDED for use at UHF because of the impedance bump they cause in the transmission line. The higher the frequency the worse the problem gets. The only connector that looks like the UHF is the "Mini-UHF" which IS a constant impedance connector. In fact Amphenol states they should be good up to 2.5 GHz. Link for spec's for UHF connectors, pay attention to the impedance and recommended frequency application range. http://www.amphenolrf.com/products/uhf.asp Now compare that with the spec's for the "Mini-UHF" connector. http://www.amphenolrf.com/products/miniuhf.asp Then for comparative purposes with the "N" connector. http://www.amphenolrf.com/products/typen.asp Amphenol would not be manufacturing the last two connectors if the UHF connector was as good as you implied. For those who think a quick and simple SWR test proves the suitability of the connectors should read the link below which does a good job explaining how a so-called SWR reading, or using forward and reflected power reading, can lead you down the garden path if the test isn't done right. http://iwce-mrt.com/ar/radio_swr_name/ -- Leland C.

Now if you can explain just what he means by "poor quality" in a way that's measurable let me know. I'm still waiting for your expert answer as to why Amphenol doesn't show the application range for their UHF connectors above 300 MHz. And if they're so great why doesn't everybody use them on UHF instead of the more expensive constant impedance connectors like the "N", "BNC", "SMA" etc. You shouldn't have to wait for me to do anything to answer that one. If they're so darn good then tell every why. You seem to know more than the company that designed, manufactures, and markets them. It seems really dumb of them to be selling the other types when as you seem to think the cheaper UHF style works just fine up on UHF, even for your TV channel 77 I think you mentioned in your E-mail. -- Leland C.

Regardless, I suggested that you -measure- this apparent loss, not calculate it (.....gee, seems I've said that before.....). I sent you a link to somebody who did using a RF network analyzer. He reached the same conclusions I did. Give it a read. I did. This is what I read: "....I must admit that the UHF type barrel connector employed here was of fairly poor quality....". That's not exactly a fair evaluation, now is it? Sure it is. The test data is quantitative, the graph and number don't lie, and his remark about the "quality" is just qualitative. No, it's subjective, which means the test data is also subjective. And the conclusions were also subjective, extrapolating the test results from a single "poor quality" UHF connector to all such connectors regardless of quality. One single connector is not even a valid sample group, let alone a fair representation of a connector type that has been sucessfully used in UHF applications for over 60 years. Now if you can explain just what he means by "poor quality" in a way that's measurable let me know. Assuming you can do anything for yourself, email the guy and ask -him- what -he- meant by "poor quality". After all, it was -his- test and -his- connector. I'm still waiting for your expert answer as to why Amphenol doesn't show the application range for their UHF connectors above 300 MHz. And if they're so great why doesn't everybody use them on UHF instead of the more expensive constant impedance connectors like the "N", "BNC", "SMA" etc. You shouldn't have to wait for me to do anything to answer that one. If they're so darn good then tell every why. You seem to know more than the company that designed, manufactures, and markets them. It seems really dumb of them to be selling the other types when as you seem to think the cheaper UHF style works just fine up on UHF, even for your TV channel 77 I think you mentioned in your E-mail. I have answered that question, and more than once. You are avoiding the answer almost as much as you are avoid the test. Are you going to do the test or not? -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
