If you were to compare the same length antennas, which would give you better reception. Fiberglass or steel. I'm currently using a borrowed 2' fiberglass mounted to the rear driver's side panel. I need to replace it and was looking at something between 2' and 4'. I know you're going to say a 102" whip will be better, but I don't want to go over 4'. The 2' currently is flush with the top that doesn't get in the way of anything. P.S. There already is a spring mounted to the connection.
