Pro at DirecTv, Question on Dish/Switch

[achille]

Hi All,
I set up a Dish 500 for a client using 2 existing RG-6 lines that run about 220 ft. I've run the check-switch on all 8 receivers several times. (Two cascaded multi-switches) Signal has been locked in and channels are being received. The problem is that the receivers lose signal at some point and go to a grey screen or search for satellite screen.
In the world of DirecTV, I would suspect the length of run from the dish being to long and insert an amp. The switches, not being powered in this case, probably cut the signal down so that it drops away from the 115 reading the meter shows. I am heading back to this job on monday so any input you guys have would increase my chances of nailing the problem. My 2nd hunch is the wire and connectors from the dish down since I didn't install those.

I never had to deal with this check switch stuff with Directv, so I'm trying to understand that difference and be sure it's not another issue that relates to Dish Network specifically. In other words, you might tell me, 'Oh, just hit the power switch while you hold the arrow key and that will do it'. (yeah sure )

Thanks for any suggestions
BOB

Dish Pro has a limitation of 200 ft. but I would imagine that 220 ft. should also be fine. Just redo all connectors to make sure that they are all OK. It's my understanding that switches closer to the receivers works best.

Is the RG-6 cable rated to at least 2200 MHz? Solid copper conductor is suggested for long runs.

Check your voltage from the receivers at the dish

Also, ensure you are using the right type of switches. You say "multi-switches", but are these really Dish (like DP34 or DPP44) switches. DirecTV switches usually won't work. Dish installations require pretty strict combinations of the proper LNBs, Switches and Receivers.

The switches are the dp34's. I know that is correct, I will be heading out to check the wiring/connections Monday as I said. I will check voltage at the dish and probably insert a couple of amps within the first steps I take. Thanks for the input.
