Looking For antenna switch

[tazman]

I currently have a Winegard HD7084P antenna on top of a 35' Rohn tower.  Don't get me wrong it's a good antenna, but it just don't have enough UMPHHH on the UHF side for Madison And Greenbay.  What I would like to do is to install 1 possibly 2 fixed position 8 bay bow tie Channel Master UHF antenna's to the side of the tower near the top.  One aimed at Madison and the other Greenbay.  What I do not want to do is to run another 2 lengths of RG6 cable.  My question is does anyone make a remote selectable antenna switch?  I don't care if I have to run a low voltage power cable to it.  As far as I know a diplexer switch only works with combining and splitting out multiple LNB satellite and an OTA antenna.  I would like to do the switching near the antennas and have the signal feed into my home through only one cable and into a future distribution amp.

A ...A/B switch

If the frequencies you are interested in don't overlap, try combining the antennas on the tower...  using a 2-way splitter in reverse.  You will take a 3db hit on levels, but you might also get lucky and not need a switch.

I've thought about using a combiner splitter, but from all the reading I've done on them unless you have the antennas you plan to gang pointed in the same direction you take a big big performance hit.  As far as an A B switch is concerned that is what I am looking for.  only one that can be mounted up near the antennas on the tower and which can be controlled remotely with a single cable feed comming down the tower and into the house.  I used to do the manual A B switch seen.  Thats a pain in you know what.:bang:
