I tried replacing my old power antenna with an aftermarket antenna but it would not work at all. So I got a used factory Maxima one. It works once then you have to unplug it for a while then plug it back in to get it to work. Anybody else seen this problem or now how to fix?

 

Sounds like a bad relay.

 

Is the relay on the antenna or located elsewhere and replacable?

 

Don't know if there even is a relay.
It just sounds like a relay typical problem
