In March of this year we were at a campground in New Mexico. Even though my digital readout will tell me several important things, like 'antenna is up', you have to read it to know it!
Well, I didn't lower it and I hit a low utility wire on the way out of the campground. Even though the antenna was pulled from the base, it still picked up a signal just fine. It wasn't too bad to have it replaced, about $150.
Our coach digital readout will also warn of the following:
-antenna is up
-must close slides to engage transmission
-shore power cord is connected
-bay door is open
-engine door is open
-window is open
