Problems With Cable and TV's

post #1 of 9
Thread Starter 
Hey guys, having some trouble, was wondering if you could help me. Its not HD signal, just good ol' fashion analog signal (isn't it digital now??) from the outside line. I am working with three TV's for my kids rooms. First TV has signal form pole, going into a splitter, then to tv 1, then to another splitter for TV 2. From that splitter one line goes into TV 2 and second line goes to another TV. Now the last TV in the line, gets crappy reception. I have tried screwing that cable line in with a pair of pliers so its nice and tight but still fuzzy. I have tried using two different TV's, one of which is a fairly new flat screen, so its not the TV. Is it because its going through too many splitters, or do I need some kind of digital converter box??? Anyways, if anyone can shed some light thatd be great. Even a new way of hooking all these TV's up with cable would be appreciated. I just don't want to pay the cable company 15$ a box every month. So if theres a gadget or gizmo that you think would help, thats cool. Thanks and sorry for wall of text.

Hi I install satellite for a living hope I can help you out.

First, a single 3 way splitter is going to attenuate less than two 2 way splitters. Second, make sure all of your cable says "RG-6" on the side and not "RG-59". When most houses were wired up years ago RG-59 was the standard but now cannot support the frequencies used over distance. Lastly, check all your connections. Sometimes the outer ground (foil and braid) can pull out or the inner conductor (center, copper core) can pull out, or either of these can become corroded or connections can just be loose.

Also just look over the wire for damage, including kinks. Frequencies travel down cable bouncing off the sides, breaks let freq. leach out and kinks create bottlenecks.

Good luck!

I might be able to offer a solution.

I had a similar problem as I had a LONG run of cable that went under my house diagonally, from one corner to the other. Where it came into the house, I had a splitter from which one line came back the other way about 35'. The front corner it started at also had a splitter that ran into the front of the house.

Everything was fine until the "digital conversion" last year. After that, I couldn't get a signal at the far end and Comcast wanted around $100 to come out and look at it. Well, I talked to the rep that handles our business account for work and he told me to look for a "Drop Amplifier". I had tried using an inline RF amp that I bought from Radio Shack years ago, but it did nothing.

I ended up getting

. $25 and it fixed all my problems.

I hooked it in where the cable comes to the corner of the house. Right after it I have a splitter.
One side runs to the front room of the house where it splits 3 ways, one to the TV, one to the PC, and one to the cable modem. The other line is the one I described above. The last TV on the line in the kitchen is at the end of about 85' of coax and the picture on it is clear as a bell.

If you get one of these and need help setting it up, PM me. The directions are very confusing. It uses a coax cable for power. I have had it for over a year now, and it's been outside the whole time, so I can attest to it's weather-resistance.

I think if you put this inline right at the cable access to your house (just before your first splitter) it will take care of you.


Hope this helps,

Rich

Hey thanks guys. I think both of you hit the nail on the head. I will look into a 3 way splitter instead of a 2 2 ways. Makes more sense. Plus, the coax I bought might be 59. Its a 100' length and it was really cheap. The center pin was also really short. I am almost wondering if the pin is too short to make good contact. Also I will probably scoop up one of those things from amazon. Great help guys. +rep for both of ya.

I was wondering too if they had something like a digital in/out switch. Where I hook up the coax from outside to in port, then it goes via RCA's to TV's...or something like that. But for time being I will look into your suggestions as mentioned above.

I never did any installations, but I did sell cable for a while here in Georgia [USA], and most of the cable you buy for cheap has a really thin conductor wire made of something like aluminum. It works for short distances, but the cable just can't carry the signal far enough. Also, most cheapo 2way splitters are [seriously] little more than a 1/4 inch rubber tube and two bits of uninsulated wire.

When you go back to the store, get a higher quality 3way splitter [rather than the cheapest one] and some better cable, and that ought to fix the issue.

Yea that was going to be my next question. Whats a good 3 way splitter choice for cheap. Some I see are 1ghz 90db or 2gz...I am not really savvy when it comes to cable tech.

When it comes to which to buy, I don't know squat about the specifications, but you aren't looking to do anything serious with the signal, so I'd suggest something mid-range. Not the most expensive, but not the bargain bin splitters either.

EDIT:

Like I said, I've never really done any installations, but one of our jobs down here was shutting off illegal connections [in the hopes of getting a sale], and most of the jury-rigged connections that had cheap splitters and low quality coax were really fuzzy only ~25 feet from the splitter. Occasionally, we'd jury rig our own 'illegal' connections when completing a sale ("If you pay me the first month + install fee today, I'll get you basic channels and they'll hook up the rest next week!") using salvaged parts from other terminated connections, and the more sturdy looking splitters and the coax with the fat copper conductor would carry stronger signals farther, even when split two and three times.

Then you'll probably be fine. I just sat down one day and took apart a cheap splitter and a not so cheap splitter that I'd salvaged from an illegal connection and was amazed at the difference.
