VHF/UHF/L-Band Antenna Mast System, monopole/dipole, 8.5 m, 30-512 MHz, 1200-2000 MHz


The system is composed of a tripod assembly which interfaces a mast (AMX85) to an antenna (VHF302000DB).  The required cables, etc. are also supplied as listed below.

The antenna is the easiest and quickest antenna of this type to mount.  All the parts needed to erect a high gain tactical antenna are supplied in the transit bag.

This tactical antenna/mast system is an improved direct replacement for antennas such as the OE-254/GRC and other equivalents.  The VHF302000DB is a dualband two-port antenna (30 to 512 MHz and 1200 to 2000 MHz). It is a one piece tactical antenna designed for use with all modern in service radios covering the band from 30 to 512 MHz.  The extra port covering the modern SRW waveform allows for future upgrades to a full network centric system.

The modern design gives improved gain and radiation characteristics across the full frequency range.  For urgent use or stealth requirements, the antenna can also be used with only the tripod support and without the mast.

If required, the AMX85 mast support can be clamped to a vehicle and be used without the guy wires.  The mast sections may be used at
random and any number of sections can be used depending on the height required for good communications.  The mast design is robust and resistant to icing conditions as well as salt mist and sand.
