We had an external antenna on the top of our 2011 Sundance 3200 FK...until this year. After starting to get really bad radio reception, we noticed that the stubby black rubber antenna is missing. While closing it up/winterizing Saturday I took a close look at where the antenna was, but can't figure it out. The rubber antenna is completely gone - no snapped off piece left. There is a Phillips head screw screwed through a plastic piece that has what looks like half of a hard black plastic ball on the side. The screw goes straight through into the roof. The half ball shape has a hole through the side, but it doesn't look like a functional connection, just a hole in the plastic. The only "connection" point seems to be the screw. I've been looking at replacement antennas, but I haven't seen anything that attaches with one screw straight into the roof. Does this sound familiar to anyone? The stereo/DVD is an Estone EX8500, but I don't know if the antenna was even related to the stereo, or if those are 2 separate components. I've tried the Estone website, but it seems like they no longer have RV stereos. Any ideas or suggestions of where to look/what to look for? Thanks!
