2004 Fleetwood Tioga 26Q, has front TV cabinet with typical Winegard amplified "Batwing" TV antenna.

When I connected our new Vizio 22" LCD TV to the bedroom antenna connector, I received fewer digital major network TV channels than when I connect to the front TV antenna connector which is located closer to the Winegard amplified antenna assembly. Before I start tearing into the RV and checking tightness of connections,etc., Have others noticed this? Does the added length of the coax cable running to the rear bedroom reduce the signal strength enough to cause this situation?

Start by checking the TVs setup. Make sure it is in the correct over the air function.
I would change out the coax between wall outlet and TV set making sure it is not the problem. Do the same in the front.
Connect the TV straight from the antenna power supply to tv. That will help determine where the problem is. If signal is better, inspect the connectors inside the wall connections.

Pulling the plate slightly from the wall will allow you to check and tighten the coaxial connection. The signal is weaker in the bedroom since there are more connections involved. Your's may also go through a switch-box which adds 3 more connections to deteriorate the signal (input, switch, output).

Substituting a separate cable as mentioned by Bud is a good suggestion.

A second RF signal amplifier placed in line between cable-out at amplifier-box and television input can greatly improve signals and stations found. I use a Radio Shack model purchased two years ago.

If you need to add your own connectors to the coax cable, get a Coax Stripper Tool. The signal is carried on the thin coating on the wire core. Not the core itself. Compromise the coating and the signal deteriorates. This per Chris Bryant RV tech extraordiaire.

That said, a Winegard "Wing Man" add-on will improve your DTV reception.

Did you also have the amplifier turned on when connected to the bedroom connector? It is probably fed from the amp so turning it on also boosts signal to it.

Amplifier --- function check first.

Then... use this neato tool:

From this, you can quickly get a sense of what the art of the possible is given your precise location, height, and also where to point your antenna.

Yup, I had the new Vizio connected to the front antenna connector with button pressed and green amp light on, ran scan again got many more channels than when connected to rear antenna connector. When connected to rear TV connector, the additional station numbers, appeared on TV screeen, but no picture or sound. I'll check inside wall connector plate in bedroom, hopefully just unscrewed.

Sounds like a bad connector or loose connection.

Coax cable and connectors eat signal strength and with higher frequencies being transmitted on DTV that makes it worse. You need to get high quality RG6 cable and connectors and keep the length as short as possible with the least amount of connectors.
