Antenna Support Mast Base AB-591/PRC-25

Item condition: Very good, used

Military Radio AB-591/PRC-25 Antenna Mast Base 

Mast base for use with AT-271 Foldable Antenna.

Description: The PRC-25 was designed to use two different antennas.

The AT-892 is a 1 meter long tape measure type antenna that's used with the "Part/Of AT-892" (p/o AT-892) gooseneck base.

This is for shorter range communications. For longer range communications the AT-271 antenna is used with the 8" long AB-591 spring base.

The PRC-25 (and the PRC-77) need to change antenna matching for the short or long antennas and so the threads on the radio are 5/16-24 to prevent the AT-271 from being connected directly to the radio.

• Thread: 3/8-24 socket top, 5/16-24 bottom.
