    vhf antenna

    Just wondering if there is a requirement for any minimum separation?

    My goal is to get it all on the same mast so I dont have to have more than one hole passing throught the roof

    You're going to want to get at MINIMUM 4' horizontal separation of the AIS and VHF antenna's, as far away from each other as you can get. The GPS and SiriusXM antenna's can basically be mounted on the same mast, we'll usually put those on opposite sides of the mast wings inboard, with the antennas mounted outboard. See below for the NMEA's guidelines for horizontal and vertical spacing. Copyright NMEA®.

    Hey Chris - to follow up on our conversation the other day:

    How far should the VHF antenna be from the mast itself? Turns out my antenn is mounted directly in line with the mast with perhaps a bare 3-4' separation.
