Thanks. Yes, my antenna is VHF+UHF. It has to stay in the attic, because of wife. She doesn't even know it's there. (Shhh!)

I would run a second line for the antenna. Combining/splitting the signals can result in significant loss. Use RG6 quad shielded cable. Home Depot has it and connectors that are reasonable.

You can use a pre-amp,but it needs to be a special one for this application.Channelmaster 0065DSB for a vhf/uhf combo antenna,plus a special diplexer at the "dish" end.There is no separate power supply as it gets the power from the receiver.


I've done this install and it works very well.I purchased the equipment from here____ www.warrenelectronics.com


The diplexer you already have at the receiver end will work fine.

I have recently installed a DISH 6000 system (which uses 2 dishes, with a coupled signal), including 8VSB module (for OTA). I have a RS antenna in my attic, and I have this fed into a RS diplexer along with the Satellite feed. Then diplexed in reverse to plug into each port (satellite, and OTA) on the satellite receiver.


My questions:

1) I am able to pull in all but one of the OTA HD stations. Occasionally, the screen goes black. Is this a reception problem? Should I add an antenna preamp? I have only seen this on CBS, but that's the only network I've watched for more than a few minutes.

2) Sometimes the OTA HD picture gets pixellated. Is this a reception problem?

3) Can I use an antenna preamp that sends power through the cable up to the preamp that is in the proximity of the antenna? The power will flow through both diplexers, and the coupler for the 2 dishes. Is there an issue?

4) Would I just be better off getting a better quality antenna?

5) The one OTA station I don't get is broadcast on Channel 9. The channels I DO receive are numbered over 25. Is Channel 9 VHF, while the others are UHF? i.e. can I tell this from the channel numbers, as I can with analog channels?

6) If a preamp is the answer, any recommendation?

I'd opt for number 4 (better antenna) first. It's in your attic. Pretty easy to try out and return it if it doesn't help. Is your current antenna a VHF/UHF combo?


Next move on to the pre-amp. Most in this forum recommend the Channel Master. I've had success with the Radio Shack. Again, because of channel 9, you'll need a VHF/UHF/FM pre-amp--not UHF only. Someone else will need to address your cabling issues.


You might also want to consider moving the antenna onto the roof. Attic installs cause significant signal loss.
