Dish Network receiver affecting OTA with diplexer

I had a 508 installed by my local Dish Network rep last year. The antenna runs into the basement through the preamp and back outside again where it's combined with the DSS signal using a diplexer. The signal is split just before the TV with another diplexer. I used to unplug the 508 and the OTA would come in perfect. I just had an 811 installed and it's the same problem. Local digital broadcasts are about 10% stronger simply by disconnecting the satellite cable from the back of the 811 or at the diplexer. As long as there is no DSS cable run to the 811, the OTA is strong. As soon as I hook it back up, there's a spark at the coax connector, and interference on the OTA.

Any ideas? If all else fails, I am going to bypass the diplexers and make a new run for the OTA.

Thanks, Don

RUN THE SEPERATE COAX. Diplexing is not the "best way" to deliver signal.

I had a similar problem, I changed to the diplexers found here:


and it solved my problems, much easier than running a 2nd cable!

Try this first, it's cheap & easy.

Your spark in the coax is the voltage going out of the receiver to the lnbs and switches it's normal and will always be there as for ota we don't have any ota signals to use in western kansas where we are at so we only diplex for backfeeding other tv's in the houses
