I have a 20' center console. I have a garmin gps built in antenna. I installed a Icom 422. Both are on top of console about 2 maybe 3 feet apart. Now my problem is where do I put the 8' VHF antenna? On the side near the GPS or on the side near the radio? Its supposed to be three feet from the radio but what about the GPS? Can the radio and GPS be next to each other and the antenna be on the other end of the console? I need to put the antenna on the console because it would be in the way anywhere else.
