I live about 8 miles from 4 local tv stations, and 25 miles from a much desired UHF station. Luckily, they are all in the same general direction.
I plan to buy a medium size vhf/uhf antenna. My coax run will be 50 feet.
Although I don't really need "gain" for the vhf stations, I do need it for the uhf station. "Some" extra gain will be ok for the vhf stations. Whatever the setup, I want to use the lowest-loss RG6 that I can buy.
Here are my questions:
1. Where (online or else) can I find the very best, lowest loss RG6 coax ?
2. Assuming that I need a pre-amp, if I only have a 50 ft run of low-loss coax, will my system work well if I mount the preamp at the tv end of the 50 ft coax, as compared to putting it at the antenna? I realize the advantage of mounting at the antenna, yet I would like the convenience of having the pre-amp inside. I am considering an adjustable pre-amp, and that would be more usuable if I had it at the tv instead of at the antenna.
3. Will a brick chimney (with no steel liner or inserts) about 20 feet from the antenna, but in-line with the desired stations, attenuate the signals ??
4. Are the Radio Shack pre-amps decent ??
My thoughts: Perhaps I will get a pre-amp that will produce about 20 db of gain. I will mount it inside. The 50 ft of coax will have a loss of perhaps 5 db, so I have a net of 15 db gain at the tv. This will be more than enough for the vhf stations that are pretty close, but I am not sure about the uhf station 25 miles away. It would seem to be good enough for that as well.
What do you think ?? Thanks for any advice !!
