better service, let them pay for upgrades with .500 cable to each boat,
with a .500 to 'F" connector for each boat. That would only cost a few
hundred dollars a boat for materials. More if the cable is jacketed.
If it isn't it won't last long in salt air. Double that for the
hardware and labor to get a good idea of the costs.


Oh, that's right. You're too cheap to even have cable TV.

Read more carefully. I said TV doesn't matter to us, it is not about cost.


Then why are you being such an ignorant prick about the issue when
you have no horse in the race? You sound more like Dimbulb every day.
I used to think highly of you, but no longer

Geez Michael, one stupid thread and you trash years of positive
experience?

Just the same, i didn't expect him to even think of pretending knowledge
where he was not well versed in the specific area under discussion.

I'm in a lot more pain lately, and I'm having a harder time
controlling my temper. I am dropping a lot of things, between carpal
Tunnel & nerve damage to my hands. I am also tired of hearing lies from
doctors. For some reason, my medication for enlarged prostrate was put
on hold for 90 days, and not being able to sleep more than an hour or
two at a time is starting to get to me after two months without more
than four hours sleep a night. There are days that I want them to cut
my damn legs off, to get rid of the constant pain. they hurt when I lay
down. They hurt when i get up. They hurt when I'm sitting, and when
I'm walking. I have been waiting over a year for the proper surgical
support stockings, only to be told a few days ago that it's no longer
available. I waited over five years for a pair of diabetic shoes. I
couldn't find anything that fit, so I was wearing a pair of old shoes
that should have been tossed three years ago. 10 years ago my feet were
8.5 wide. Because of Diabetes and circulation problems, they are now 11
EEEEEE (yes, 6E) and some days I have trouble even getting those on. I
have 'Turned the other cheek' so many times that I no longer care.

Yes, just call the cable company, tell them you will change to satelite
because it doesn't work.

They will do it for nothing and very quickly.

Hi All,
I'm on a boat, about 170ft from the utility post.
Recently our cable company switched to the wonderful world of
Digital TV. I got the new digital converter and had no picture.
I took the box back and got a second box, still no picture. 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.
I don't has access to electricity at the utility post, so an amp is
out. Although I could try an amp at the cable box end. Is that reasonable?
I would run two cables if there was a way to make it increase signal
strength.
Getting anymore from the cable company is not an option.
Any ideas to get a better signal?


Yes, ask the cable company to change the tap in the distribution
amplifier from (for example) -40dB to -34 dB. IOW, they can up the
signal level in the cable vs installing a lower loss cable. (You're
probably at the point where there isn't a significantly lower loss
cable available anyhow.)

Actually, first ask them to measure your signal strength at the
distribution point on your boat where their cable attaches and look
over their shoulder as they do that. They have specs and they need to
meet their specs. I had a ton of problems with Internet here until
doing that - finding they didn't meet their own specs - and when I
made them meet their own specs all was fine. They met their specs by
changing the tap.

Those amps with power inserters, available from Radio Shack for around
$40-50 as I recall, do work well, HOWEVER, I have had 2 of them burn
out on me. They do run rather hot. But when they work, they usually do
the trick. You power it from the TV end and the inline amp has a
blocking cap so you don't put DC on the whole system. Theoreticaslly,
that is what you need. I think you should put one amp every 50 feet
but that may not be possible for you.


Use a 15dB gain drop amp with power inserter, but that's just a guess.
Would help if you actually knew signal levels like what the receiver
requires for optimum reception and what the cable co sources. Putting
the amplifier at source gives you a typical system noise figure of
3dB, but putting it at your end limits your NF to 10dB minimum from
the start.

What kind of coax has 10 dB loss per 50 feet, and at what frequency?
Those RS amps have no equalization, so the low channels would overlaod
the front end, and the high channels would still be snowy if you need
more than one or two..
