Long cable to antenna.

I live in an apartment building where I'm on the first floor with almost no available reception, but I'm a security tenant having access to feed a wire up above the 6th floor, on the roof of the building as high as 8 floors if needed. I guess the problem is, I can't pick a spot of less height for a shorter cable run, so I'm stuck with a run of somewhere up near 130 feet of cable to get to the antenna. Firstly, and most importantly, is it possible for the signal to arrive through this length of cable at my tv down on the first floor with at least a few stations available? Would some kind of amplifier be required up near the antenna end? (Possible to hide away in the boiler room, high and dry, then feed down from there...) I'm at (redacted by moderator to protect OP's privacy) http://www.tvfool.com/?option=com_wr...cc49c5630f80eb. It would appear that there should be good signal strength here, at the height of the rooftop. I'm trying to avoid cable or bell costs, and like the idea of OTA hd tv, even if its only a few channels. I have line-of-sight to the CN tower, and the antenna would be almost high enough to clear the escarpment toward Buffalo...
Any advise is appreciated.

I would try this install with no amplifier... At the highest UHF frequencies RG-6 should not have more than 6 dB loss per 100'.

If you prove the need for an amp (Verify a good signal at the antenna, then check at the end of the coax run);

You have fairly strong local signals so even though the ideal location for an amplifier is at the antenna, you have plenty of flexibility.

If you are going to use factory built cables, use a 50' cable from the antenna to a Channel Master CM-3410 (presuming the CM-3410 can be located out of the weather). Then use a 100' cable from the output of the amplifier to TV or splitter. If no power is convenient, you can use a power inserter located near the TV

Reception of the US stations calls for a high gain UHF antenna such as the Antennas Direct 91XG or Winegard HD9095P. The signals are weak, so a preamp needs to be mounted at the antenna. The Antennas Direct CPA-19 would be my choice.

I would treat this as a separate antenna system. You can use an A/B switch or an HD STB/tuner. http://forum.tvfool.com/showthread.php?t=2882

For reception of the Canada and USA Tv stations/channels.

Install a Winegard HD7696P antenna with a Antennas Direct CPA-19 preamp.

Aimed at about 118 degree magnetic compass direction.

Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.
