TV hookup

Next to the inside connection for the TV, there's a small button which, when slid to the left, makes a small light burn.

Any idea what this is for?

I haven't had a chance to test it out yet if it does anything, but have noticed in the past that our TV signal when hooked up to a cable on a campground is pretty staticky.

See attached image.

Thanks.

Hi - I'm guessing that's the button to turn on the power to your tv antenna (for watching air channels) and to turn it off (if watching cable tv connected from the campsite).

Not sure though - yours looks different than mine....

It does turn on power to a signal amplifier.

In the "batwing" style of antenna, the amplifier is in the center part of the antenna. The wall plate switch sends 12 volt power up the coax to power it.

However, a red light at the wall plate just means power is on, the amp could be bad. The UV light breaks down the plastic of the antenna. Water gets in and corrodes the circuit board.

Hook a TV up to the coax connector, raise the antenna and turn on the amp.

Make sure the tv is in "air" mode and do a channel search.

They work really well, all things considered.

Regards,

JD

On our rig it's a push button ... but it's no doubt the antenna booster. It needs to be on (lit) to use the roof-top antenna.

Yeah, it is the slide switch for powered roof antenna "booster".. If you are plugged into a cable system, at an RV park, the booster should be OFF, as it screws up an otherwise good cable signal.. When using solely the roof antenna (hopefully fully extended and properly aimed, and within range..) it will make the signal sharper sometimes..

Thanks, I tested it and it does have a significant effect on the quality if some TV stations on antenna.

I've been fighting intermittent signal dropout to my tv for some time and based on this thread I bought a new amplifier plate. After installing it the problem was eliminated and as I looked over the old one I found that the power fuse connections were loose, allowing the fuse to rattle around in the sockets and intermittently disconnecting power to the amp. If you're having this sort of problem take a look at the terminals for the fuse legs because that could be your problem.
