Antennas Combining UHF and VHF — Community

I had to use to use two seperate antennas because of space limitations in my attic. The better combination antennas can be very large due to some of the elements being very long or long booms. I ended up with a magnadyne style UHF and a cut Yagi (tuned to my only VHF HD station CBS). When I bought both of my antennas the sales guy sold me a small device which combines the antennas. There is balun mounted at each antenna then a short run of RG6 from each antenna to the combiner then a single run of RG6 to the TV. I know there are rules governing how close the antennas can be without interfering with each other but again space dictated my mounting locations. The way I have everything connected seems to work for me.

If space is not a concern the combo may be the way to go.

BTW, on mine I used a U/V combiner for about $5 in reverse. This puts UHF and VHF filters on the diferent antennas to help isolate them. Tacky but it works... It did result in poor analog response and if I wanted to do womething about that then I should use a real/professional U/V antenna combiner.

If an ordinary splitter is used to combine a VHF antenna and a UHF antenna, there is a 3dB penalty for both antennas. In a weak-signal neighborhood, that would be a bad idea. There is a common device (at Radio Shack and others) called a
