Question for those of you serious about antennas. I've got a 30' TV tower in my backyard that came with the house. It has a 22 element antenna on it that is probably a million years old and runs 300 ohm wire with a non-functional turn unit and something on top that looks like a 2' x 2' square mesh. I get 26 channels reasonably okay running the 300 ohm into a 300/75 converter and a $30 Radio Shack amplifier. That powers 5 Tivos. There is 1 channel about 25 away to the NW (opposite direction of my city's antenna farms to the SE) that we can't get and a housemate wants so he's putting in one of these (HDTV TV outdoor Antenna LPDA Professional Grade 10dBi VHF-UHF Log Periodic | eBay) which if the link doesn't show is a $40 eBay 10dbi VHF-UHF antenna that "provides a constant gain across the band from 170-213 and 450- 800MHz for the HDTV bands in USA. US Channels 7-13 plus 14-69. VHF UHF TV in Europe. (reaches 790MHz)." Since he is paying to put up the one he said he'd pay the installer to replace my current antenna with one of these as well. I just need to pay for the antenna. I like the idea of new antennas. My only concern is a station that's about 50 miles away to the North that I somehow which has Heroes and Icons which I can't get locally... Is it worth the money to replace the existing 300 ohm antenna with the newer one? Any chance I'd still get that north channel if one of these is pointed NW and one is pointed SE?
