Ernie,

Who sells a reliable "radio" a/b switch ? I am using a Radio Shack infrared A/B switch and a Radio Shack wireless infrared repeater to get the infrared a/b Transmitter commands up to my attic. I must say that it is less than dependable.

Since I am using two antennas, another alternative is a diplexer but I tried a splitter in reverse and had the channels stepping on each other causing more problems. I am not really sure if a diplexer is different from a splitter being used in reverse or not maybe you or Daniel T know.

The other device I have looked in to is a UHF Join- Antenna but I was confused on just how I can get one frequency only out of the device to merge it with the other antenna.
