One day a couple of weeks ago the electric antenna in my 400e didn't go up. So I removed it took the cover off if I spun the belt by hand the antenna retracted and went up ( manually if you will).
By the time the week end came around the antenna started going up and down , just like it should. So I was happy!!!!. About 5 days later did the same thing, then the antenna extended and stayed extended. Couple of days later it went back down, at this point it hasn't reamerged. ( does this mean six more weeks of winter...lol).

I'm thinking the antennas ok?? But its not getting a signal, sometimes. Ideas for things to check, and where?

Thanks for your help
