ever sense i bought my trailer, i have had an intermittent problem when receiving from the antenna. the dealer, as myself, thought the problem to be in the connector at the point the coax went thru the roof.
well recently, i replaced the antenna and all worked without problem. then i went into the old antenna and found the F connector that fed to the outside world was not tight (nuts that sandwiched the plastic ant housing weren't tight on the f connector). found out i could have tightened it from the outside. the nut on the inside is crimped so it doesn't move easily.

this and the next picture is suposed to show that there is slack between the housing and the nut. sense it wasn't tight, the ground eyelet had hit and miss contact with the metal f connector.

shows the rest of what is inside. there has been discussion elsewhere abt the amp being located in the switch area. shows the amp is actually in the ant.

Did you replace the old antenna with opne of the new digital bat wings? If you did, how does it work and did run into any issues installing the new antenna. I am probably going to have to replace mine soon.

I have often looked at these thing's and wondered , If one would take the rx amp out and hook coax directly to the antenna just what frequency (s) would it be resonant at ?
Maybe use for 2 meter SSB ?
Just have been too lazy to try it and have not had one to play with, anyone try'ed it ?
