A/B switch use on Satellite feed?

As my diagram above shows, I am using a single input point to provide for 3 different sources, all requiring different, mutually exclusive, devices.

1. Cable (straight shot to video control center)
2. 18" round antenna satellite, only satellite receiver inline
3. vuqube 2100 satellite, with 2100 controller AND satellite receiver inline

Without good, functioning diplexers and A/B switch, it wouldn't work, but it works well in all 3 modes.

You had a bad diplexer.

Diplexers do work very well. I just prefer one device over 2 but that's not to say it is any less effective.

A/B switches work very well and those I do recommend.

ON MANY (NOT ALL) Sat receivers you can wire as follows.

Cable inlet to A/B swtich common, A to the "TV-ANT IN" on the Sat receiver, B to the LNB in (A for antenna/analog B for lnB or Binary) and TV-OUT back to the winegard wall plate cable inlet jack.

now you need only flip the switch from Park to Bird or back. and otherwise it's as designed. (Well turn off the sat receiver for park as well).

That said. I really like adding genuine RG-6 and ignore the factory lead.

You may have had a bad diplexer or hooked it up wrong. Don't condemn something with a single trial. I have installed many with no problems.

Radio Shack A/B switch

x2. They look cheesy, but are built really well with no measurable loss on the receiver at Ka

we have splitters for our satellite TV in the bedroom. Sats2Go in Houston TX put them in. We use the "input" function on the remote to accesss satellite or cable.

Splitters (actually called diplexers) and A/B switches are OK as long as they pass power. Be sure they say this. My multifunctional setup has 1 A/B switch and 2 diplexers. Here is a diagram of how mine is setup.

The video control center selects CABLE or SATELLITE. If I select SATELLITE, the A/B switch selects round 18" dish, or Vuqube 2100 with its controller inline.

Note that 1 diplexer and the A/B switch pass power both ways. One diplexer only passes power one way so 13v or 18v isn't backfed into the video control center.



This diplexer passes power only one way:



This diplexer passes power both ways:

Yes.
