Installed my Cobra 75 the other day and I just received my antenna today, when I put the antenna on I am still not receiving anything on all channel scan. I switch it to weather and receive local weather no problem, but have yet to hear any am transmits. Is it possible something is wrong, is there a way to test, or should I just try and find someone local with a radio to test it out?

Install is a cobra 75 hooked right to the battery.
Wilson flex antenna

 

The antenna might not be grounded properly.lets see a pic of how its mounted.

It looks good, just double check the ground wire. Make sure you have a clean contact area.

 

Ok thanks for the input, I am going to try and scrape up the washer a little to make sure its a good ground. Also a friend of mine said when he had his radio he never received anything locally either, only people on the trails. Maybe its possible no one uses them around here. I am getting FM weather no problem.

 

yea either no one is talking or you have your squelch set too high.

 

Turn the squelch down until you hear static and switch to CH 19. You should hear some activity from the truckers.

 

Same issues here. Using a firestik antenna with quick disconnect and spring. Going to check my antenna ground tomorrow. Subscribed.

Cheers!

 

Did you tune the antenna ?

 

I don't think you are supposed to hook up that wire on the Wilson antenna in your situation. Try disconnecting the wire.

From Wilson's site:

Wilson's exclusive impedance matching transformer is connected through the external wire at the bottom of the FGT and Flex series of antennas. It is NOT a ground wire to increase the ground of the antenna, although using the lead does make the antenna DC ground. It is used when you are not able to get below a 2.0:1 SWR even after tuning. This generally indicates a mismatch of impedance between the coax and the antenna. This can be caused by poor ground but is generally attributed to the mounting location. It re-inserts 25 ohms impedance at the antenna feed point and brings the system back to the 50 ohms required. It is not a tunable device, therefore it is not fooling the radio into thinking the system is matched. It is actually matching the antenna and feed point to the required 50 ohms impedance for the coaxial cable. The most often time it will be used is when the antenna is mounted on the top of tool box in the bed of a pick-up, or on the passenger side of a tractor using co-phased antennas.
