I amplified the signal on the hookup side and it helped the signal a bit. If you have a fuzzy signal you will only get a stronger fuzzy signal, the amplifier increase whatever signal it gets.

I don't see that doing anything as the signal is being delivered via cable to the coax connection point at the campground. If you're using your own sat/dish then it's all going to based on the signal you're dish is receiving, can't really improve on that. Now your roof antenna should already have a signal booster button inside your RV for over the air signal boosting. Hope that helps.

I do not think what you are wanting to do will make any difference. I would first make sure the power boost is on. You will see a small light on the wall plate. The cable and ant cables both end up at the same place, the wall plate for the coax. I found with the digtal signal its much more important that all of the cable connections are wrench tight not finger. I would get to as many connections you can by pulling the wall plate off and any other items that will use the coax, tighten all, I think it should improve your picture.

How old is the antenna on your roof? If it is more than 3 years old, it may not work well with the new digital TV broadcast. There is a quick mod that Winguard puts out that attaches to your antenna to receive digital signals. I tried one and saw a reasonable improvement. With the new digital broadcasts, you should not be seeing "fuzzy pictures". When the signal gets weak it freezes and jumps (picsilates). Older analog stations you would see static (what we call noise in electronics). Digital signals pretty much eliminate noise. So if you are getting a "fuzzy" picture from a digital station, then it sound like you may need to check connections and or equipment after the receive point. As far as using an amplifier outside, yvsem made the point that you only amplify what you get. When I was in the Home Theater Business, I used to say, "if you amplify crap, you just get more crap"! Hope we have helped. Good luck.

if ur putting a better antenna on ur cable input (more elements...more directional) and u have more height, i'd say yes. it goes back to a preveous response...u can't amplify it unless it is there.
there are antenna's out there that have better gain than ur bat wing that u can attach at that point.
when u do that, the amplifier in the wall is useless. it is there to amplify the bat wing signal.
i put the attachment on my batwing and saw very little improvement.

The way I understand the Winegard system that is on our RVs, the wall plate is the coax switcher and power supply for the amp in the antenna head (the big white box that the wings stick out of).

Pressing the button (and thereby turning on the green light) switches the wall plate to roof antenna and routes DC power up the roof coax to the amp in the antenna head.

Switching the button off (no light) switches to the Cable input and shuts off power to the roof.

I had always thought of the amp and cable being fed into a splitter.
I'll have to play with that when I get home.

I had to give the same thing a bit of thought, but a splitter splits 1 signal to multiple outputs. A combiner takes multiple RF feeds and puts them to one. I very much doubt it would be a combiner due to the frequency interference from a cable feed and the antenna RF. From memory of looking at it, there is a small circuit on it, perhaps a transistor or diode to block one source from the other. I am now interested in finding a schematic for the switch plate. These forums are so addicting by making the mind wander and promoting the thirst for knowledge. Such fun!

Here is the Manual for the wall plate amp (again).
