Jensen Radio

We have a 2016 TBS 16.

The FM radio reception is very poor.  Anyone else having this issue?  Could it be as simple at the FM antenna is not properly hooked up? 

Thanks,

Thanks, [/quote]We had the same problem, couldn't get any fm channels to come in and the tv reception was not good.  Was told it was loose coax wires at antenna booster.  I didn't do the work so I didn't see which ones.  After the fix, we get a huge amount of fm channels now and much better tv channels.

We had the exact same problem with our camper after we brought it home from the dealer back in December. Had to take it back in and they had to fix it as you described above. Works great now, but they must not be doing a good job of connecting everything together at the factory when manufacturing them.

The antenna on my new 16DBS built in August 2015 seemed worthless.  After reading this thread I downloaded instructions from Weingard on the Roadstar 3000 that's installed, and also on the wall plate that the coaxes tie into.  The first problem I found was the antenna was connected to the set2 output and Jensen radio was connected to the antenna input.  Swapping this and turning on the booster switch which feeds 12 volts to the active antenna and the TV reception is now really good.  The radio is no better, and I think there's a problem with the coax from the set2 output to the radio.  For sure the coax connectors are loose (all of them) - poorly assembled at the factory and certainly not tested.  I'll pull the radio out tonight and debug the coax and figure out what else is wrong.

We had to turn on the Signal Booster to get FM as well, booster off, no FM.

I have a 2014 14 DB which I took on an extended roadtrip in the summer of 2014 and could never get the TV to work when connected to the external coaxial connector on the outside.  I also had a problem with the booster (no over the air tv signals).  The factory sent me a replacement booster which I correctly installed but could never get the outside TV connection to work.  When I returned and took it to a dealer, they back-tested the connections for resistance and discovered that the factory never connected the external TV coaxial connection from the outside junction box to the internal box.   Apparently the guy at the factory that was supposed to run the wire inside the trailer was absent that day and no one bothered to check the connection.  I have also discovered that the FM radio will not work well unless the powered antenna is turned on.  Everything is fine know.

Yes, we had a disconnected cable too. Poor workmanship at the factory in this area, it seems. And yes, we need to have to power booster on in order to get any radio or TV reception. But when we do have it pushed on, we get great TV reception and a lot of radio stations. And our outside cable input works well, so that must be OK. Glad that we all finally have it worked out now! Geez, it shouldn't have to be so hard!

Geez, it shouldn't have to be so hard![/quote]How did they connect the outside to inside cable if it was found to be disconnected?  I checked the DC continuity from the cable on the side of the trailer to the cable plugged into the cable input of the Weingard wallplate assembly and there is no connection, not on the shield or the center conductor!  I haven't rolled the trailer up to the house to hook to an external antenna feed to check it RF-wise yet, I suppose it's possible they used an isolation transformer in the feedline to eliminate ground loops at a campsite, a good idea, but that seems unlikely.  More likely the cable got cut somewhere, good luck to the guy who has to refeed that through the frame!

I've managed to feed the TV and radio and get good signal with the Weingard power switch on - however, wiggling the cables causes the signal to go away.  I pulled out the Weingard unit and re-soldered the PCB to no avail.  The RG6 cable going from Weingard switch to the roof antenna has horrible non-crimp F connectors on it and I think the 12 volt feed to the antenna drops out when I wiggle stuff.  I have normal old-fashioned crimp connectors to put on tonight.  Sucks to spend all this time to make the antenna work on a brand new trailer.

Otisw- it wasn't the outside cable connection that was bad, it was the antenna connection. Yes, you shouldn't have to spend that much time fixing this. They should be manufactured better in this area.
