what is the swr on your antenna? what antenna you have?

 

What kind of antennas are you using. Your sleeper is it a mid roof, is the tall sleeper. The side mounts can work, usally if theres a problem it is the coax not the mount. There are inline connectors in the middle of rhe antenna cable these sometimes come apart and simply need to be screwed back together, You will need a volt/ohm meter and a swr bridge the built into your Cobra will work just fine also you will need a jumper wire to short out the antenna mounts on the side of your sleeper. remove both antennas and disconnect the antenna cable from the rear of the radio. check it with the ohm meter and it should read open, now connect the jumper between the antenna mount and ground and recheck at the radio end of the coax (antenna cable) you should see a dead short, check both sides, if you donot see the short find the inline facory splices and reconnect them. Till you are sure the antenna cable is good and continuous out to the mount it is really difficult to diagnose this online, but I'm game to give it a go. These mount can produce good results, clean tight connections are most important. I would use 4' francis or 4' firesticks. Because of the mounting system I would not go any taller than 4'. If your going to use a large antenna like a Monkey Made or a Stryker you need a after market.

Location of antennas will change what you hear, If your pulling a refer or a drybox you need co-phased or dual antennas, if you pull a flat or tankers you can use a single antenna. think of your antennas as a light stick, anything that blocks the light would be blocking radio signal from that direction also.
