Product Overview

Southwest Antennas Part # 1000-043 is an omni-directional blade monopole antenna designed for use with manpack and hand-held military radio systems operating in the 30 - 88 MHz VHF band.

The unique blade design allows the antenna to bend and return to vertical when encountering objects such as tree limbs and branches. The antenna design allows the product to fold in on itself for compact storage and transportation and for body worn applications. Disengaging the product's velcro strap allows for rapid deployment and in its extended position allows for maximum RF link distance and communication quality. An integrated gooseneck base offers flexible positioning options for the radio operator.

Note: Matching network can be modified by Southwest Antennas to optimize antenna performance on specific radio systems. Contact Southwest Antennas to discuss custom tuning needs.
