Antenna

I had to replace the booster in our MH. I was lucky and found an exact replacement.

Though unlike BIll I've never seen the wall plate not put out power.... I've only worked on 2 RV's with this problem and both of 'em was bad cabling.

I DO know however it is possible for the light to be on.. the fuse to be good. and a DIFFERENT part of the wall plate assembly to go diodes up and not put out power.. I've seen that on so much other hardware.. So I support BILL's comment

OR he mine. take your pick we are in total agreement.


THe one thing many do not see is the roof conneciton. ON Some RV's it sticks up under a mountain of caulk. On mine it was buried under a cover and not visible. I knew it was there so I dug it out and replaced/repaired as needed (And as of 7:30 this AM it was working) (I'm watching DVRed tv now) . The other RV I worked on was a Sticks up under caulk kind. that one it was either the lower connection (which I was not willing to dig down to) or the wall cable. I got 'em TV by running a cable out the window to the antenna for their stay and when they headed out they stopped by a shop and they replaced the in-wall cable. ONly time I've ever heard of that cable going bad (And I've strung miles of coax over the years)

I have seen bad cabling many times. I have also seen the power light on and the wall plate not putting out any power.

If light on fuse good.. He did say light on.

I do agree there can be another issue with the power supply/switch unit (Wall unit)

But I'm going with the roof connection as the problem child. I've seen this twice in my travels (once on my own RV) and both times.. that was it.

Did you check the fuse on the backside of the panel? On my booster, there is a fuse

OK, so start at the power supply to ensure it is putting out 12V and if that's working run the new coax to confirm the antenna is OK.

To check the power output of the amp, just insert the end of a jumbo paperclip in the set one F connector and touch the positive lead of you DMM to the paperclip and the negative lead to the threaded portion. If you have power there start looking for the ends of the cables. I have two pieces, one from the power supply to the antenna and it is in the area between the ceiling and roof, one that connects to the antenna.

Sometimes that one in the ceiling is a bear to get to.

Two options.. IF you are the original owner only one

Bad coax The coax likely runs in two runs. From the box with the light that comes on to the roof. and from the roof to the antenna.. ON MY RV doing routine roof maintenance I tore up the connection in the roof (It was kind of nasty anyway since moisture had gotten to it and rust happens.. I put on new ends and a new barrel connector (Double female) sealed it up to water proof (I do that real good) and .. i'm watching Recorded OTA TV from about 45 miles out as I type.

But if you have no power to the head. that's suspect 1 2 and 3
