Well, here we go again with yet another diplexor discussion. The reason why i'm bringing this up is because one of my local broadcasters just recently went on the air with their digital signal. First for the people that don't know. Diplexors are used to combine the input signal from a satellite dish and an input from an over-the-air (OTA) antenna. Both are carried into the house on one cable. Then inside there is another diplexor that splits the two signals back out so one can go to the satellite receiver and the other can go to the TV or HDTV decoder to receive OTA broadcasts. This eliminates the need to run a separate cable for OTA.
My setup is a standard Dish 300 pointed at 61.5, outdoor medium range antenna, 2 Radio Shack diplexors (inside & outside) and a Model 6000 receiver.
First I hooked up two separate cables. One for OTA and the other for dish. No diplexors.
Signal strenth on the dish was 98.
Signal strength on OTA digital was 83%
Then I hooked in the diplexors and got rid of the extra cable.
Signal strength on the dish was still 98.
Signal strength on OTA digital was 80% (only a 3% drop)
Other analog channels on OTA before and after look exactly the same.
In my opinion diplexors work great in this kind of setup. The OTA digital signal showed no pixelation problems or other anomolies. The OTA and satellite channels work flawlessly.
Despite what some people would say, diplexors can and do work for certain types of setups. Yes, running a separate cable is always the best but when that's not feasable, diplexors should at least be tried. IMHO
