I took a look on AntennaWeb and your
in good shape for availability. The odd channels are Fox and UPN which are VHF. Rigging UHF only would be so much easier.Now the problem. Omni directional (non-directional)antennas are subject to multipath problems which you will have plenty of with the close proximity of the tower farm. DTV doesn't like multipath. You can't compare it to analog where it will just cause "echos" in the pic, DVT won't work at all even with moderate multipath. Bottom line is you'll have to try it to see if it works. At your signal level a simple one bay bowtie would work well but will be directional. A 4 bay like the Channel Master CM-4221 might have enough gain off the back of the antenna where your reception would not be lost as the boat swings. You could try the antenna at the link below. Antennas/reception is a little science and a little voodo. Watching OTA HDTV is worth the effort!http://www.starkelectronic.com/cm3000a.htm
