Signal that cycles from 90 to zero
Posted 04 August 2011 - 05:51 AM
I'm a newbie to this site and would like some help with my Sat installation. Just moved and setup my DTV system. I brought my receiver but bought & installed a new oval DTV HD dish & mount. I have a great strong signal that cycles from 90's to 0 to 90's about every 5-8 seconds. Really good image, then the searching message. Totally clear line of sight to horizon, not tree one!!! I have taken my receiver to a friends with DTV and it works great there and tried his receiver on my system with same results. Do the LMB's cause this kind of issue? Also, no switches just dish to receiver for RG-6 run and really solid compression fittings on ends too.
Any suggestions? Just a standard DTV HD receiver with the balun.
Thanks in advance for the help!!!

What are the signal strengths for each transponder on each satellite?
What model receiver do you have?

I tried swapping receivers, and same problems. Replaced the cable from the LNB's to the ground block to the SWiM splitter, same problem. I finally got a really long coax cable and ran it from my upstairs down to my basement where the splitter is. After a few days and zero problems, I attributed it to a split in the coax cable somewhere.
The original coax in the house was ran by the builder. The cablers were a little goofy and did a crappy job, IMHO. They mostly used push on connectors, and who knows if there was a split or kink somewhere. I got them to come back, tested it, and said things were fine. I gave up and finally re-ran the coax and haven't had a problem since.
If I were to suggest something, I would suggest connecting new cable from the LNB to the receiver, just for testing purposes. If it works fine, then run it through the grounding block and you know it's the cable.
hope that helps.
