In my continuing dilemma for antenna placement in a sailboat marine application, I am giving serious thought to mounting a pair of cellular antennas at the mast head, and placing a the Peplink device as close to the mast head as possible. Obviously POE is ideal in this scenario, and this is supported by the BR1 Mini. I am assuming that the Mini has the same performance and the BR1 MKII and other units.
This brings up the issue of separate between the cellular antennas and the VHF antenna on the boat. From the diagrams I included in my other thread, Cellular / WiFi Antenna Separation, there is recommended horizontal/vertical separation between VHF and cellular antennas of 2’. I have illustrated that in the diagram below.
So this would be the ideal situation, to minimise interference even when the VHF radio is transmitting. However, given the the VHF radio (25W) only transmits very rarely, can these distances be reduced so that the only concern is ensuring the metal aspects of the antenna don’t interfere with each other? There is an AIS transponder transmitting on the antenna, which is a small burst at 2W every 10s.
