VHF antenna minumum distance apart TX/RX
Ok so I had some radio equipment installed on a boat and they installed the antennas WAY too close together. One antenna is a standard fiberglass VHF Marine antenna connected to an Icom marine radio. The other is a SS whip (pctel MWV1322s to be excact) connected to a Motorola government radio. Well the government radio is very high wattage (45 or 65) and the antennas are only about 6-8 inches apart. so needless to say when I transmit on the Motorola radio, it overloads the Icom and it now barely pics up any marine traffic.
Since it is just a standard NMO mount I am going to move the antenna for the Motorola radio. Since they are both VHF radios, what is the min. distance apart I need to put them? Obviously more is better but it is on a boat where real estate is limited.
Also, the further I get the motorola antenna away from the Icom, the closer it will be to the vessels radar unit..any issues there with either the radio or radar unit?
