I have about an 80' run between my TV and my new antenna on my roof. What's the best kind of cable I can get to connect between the two?

RG6 Quad Shielded cable should be fine. You may want to invest in a pre-amp to counter cable losses (its still a very short run, you will likely gain much more than you'll lose - maybe bring in a marginal station better). RG11 is a better quality cable, but over only 80ft/25m, its definately not worth the effort and money to gain a couple of dB at best..

Guest,

Per, N---Au,

Before you buy an amplifier or a pre-amplifier take note that it depends on the received signal levels. A strong signal can be amplified far beyond what your TV set will accept and you will receive a blank screen for your efforts and cost.

He is correct, Quad-shield RG-6 is the current standard, BUT standard RG-6 or pre-existing RG-59 in your walls may work perfectly for YOU (and perhaps NOT for your next door neighbor). The only way to know is via testing.

For an 80 foot run I would use RG11. A preamp is also a must.

I have a 210' run for my antenna system which is on top of a ham radio tower. I used RG6 and switched to RG11.

With RG11 there is a significant but not overwhelming difference. It also gives me a buffer for weather related signal attenuation.

As for the preamp, sure you can test but unless you're right near the transmitters, 80ft is going to significantly attenuate the signal. I would say a preamp is going to pretty much be a must. But test first if you must. It is always easy to put a preamp in line later.

On one of my three (soon to be four) antenna systems I am using RG-6 quad running around 115 feet and the signals are split 4-ways using no distribution amplifiers or pre-amps.

I strongly suggest you test first: after you test, you can easily add a preamp if it proves to be needed.

I am running without a preamp now - and everything is break up city. On a clear day I get full lock on everything but as soon as some clouds come across the sky, my signal is toast. It is not reliable enough. Can't wait to get my preamp back from the menders. :)

At the base of the tower I can receive everything acceptable but even then I lose my most distant channels (KYW, WCAU) which were reliable with the preamp.

BTW, can we have a TVFool from the person who started this thread? That will help quite a bit.

I would only use RG11 for runs greater than 100 or so metres (100m=330ft) (and even then it would depend), or if there I am running trunk lines to many buildings in a large MATV system. The difference between RG6 and RG11 really isnt that big to consider doing it for shorter runs. That and its an absolute pain to run down walls or anything like that.

I think the rg6 quad is great for digital TV setting lower signal loss and great interference shielding for the best signal quality, is sometimes better an soft but robust signal than louder and noisy digital signal full of interference .
