The Signal Booster on My RV's Antenna is Not Working

Antenna booster fuse in a 2004 Windsport Motorhome where is it?

ANSWER: Thanks for submitting your question on our Ask An RV Question Page.


I am going to assume that based on your question that the antenna amplifier for your antenna no longer works. I am also going to assume that you have a Winegard Sensar Antenna System on your Motorhome.

The amplifier (Signal Booster) is actually built into the antenna itself. The switch you turn on in the RV is a power supply that provides the power to the amplifier in the antenna through the COAX cable that is attached to the antenna. There are no replaceable fuses between the power supply and the antenna.

If you turn on the power supply switch and the LED on the switch lights up it means that the power supply is working properly and should be providing power to the antenna's amplifier. In that case the only possible problem that would prevent power from reaching the antenna would be a loose Coax Cable connection on the antenna or on the power supply. The COAX cable could also be bad.

If the LED on the power supply is lit and all connections are good and the cable is good it means that the amplifier on the antenna has gone bad and you will have to replace the Antenna Head.

If the LED on the power supply does not light up you should first check your RV's electrical compartment for any blown 12 volt fuses. If all of the fuses are good then you should check for any loose wiring connections on the back of the power supply. If all connections on the power supply are good then you need to replace the RV Antenna Power Supply.

Hope this helps.

Problem was shorted co-ax.
by: Anonymous

I had same problem. Green light came on for a split second, then off. The co-ax on the ceiling got twisted around the antenna, which ripped the co-ax, causing a short. repaired the co-ax and now the amp works again. Green light stays on.

Excellent Response
by: Anonymous

An excellent response to the exact same problem I am having. But, after reading the response, I'm wondering how one could test the coax cable before purchasing a new antenna head. THe coax cable goes into the roof, and I am assuming down the inside of the wall to the winegad power receptacle and does not look anything like an easy job to replace.

Usually, the booster switch is located next to the 12 volt outlet for your TV. Push the button in & you'll have the booster on.

Antenna Signal Goes out when lights turned on
by: Anonymous

They found the problem, the LED lights were putting out a frequency that interfered with the signal. They installed new LED lights and the problem went away. Who would have thought? So if you are going to buy a new camper with LED lights may want to try turning on the TV and get a good signal on all the channels then turn on all the lights to see if you still have a signal.

where is the antenna boost button?
by: Deryl

I have a 2005 Windsport by Thor, do you know where the antenna boost button is located. I have looked all over around the coach and cant find it. I have my antenna raised up and scan for channels but cant boost the signal.

Antenna Signal Goes out when lights turned on
by: Anonymous

I have a new Flagstaff Classic Ultra Light. The antenna is in the front bed room and the tv is in the other end of the camper. When the lights are turned on in the front bedroom I loose the signal to the tv. It only happens on the lower channels, 2, 9, and 5. Channel 33 stays on. The booster light is on and the TV will not pic up any signal if off. I also have the "wing" on my antenna which helps the signal when the lights are not on in the bedroom. Any ideas?

Coax short
by: Anonymous

If light on PS blinks and then does not stay on when button is depressed, it could be a short in the coax. Disconnect coax from antenna wall outlet and also on roof at antenna and check with ohm meter (multimeter set on ohms) by placing one lead on the center wire and the other lean on the connector. If you read any resistance at all, you have a short in coax which is causing your PS to shut off.
I had this happen on my new copper canyon. when installing the panelling they shot a staple thru the coad shorting the center wire to the shield....
