Shakespere antennas I have always read and found to be excellent. Haven't read anything about the digital and whether that would be compatible with your existing unit. Even thou your unit is low should be usable. Clean antenna connection??? Is your radio in the weather or in the console? Even thou it is "waterproof" maybe it took a hit. Or the routing of the cable too close to other noisy wires?
i think i'm going to start from scratch, new all around. any brand of radio better than others. looking to spend 200 on the radio. mr h - you splash that new rig yet?
