Tactical VHF Dipole

The 20-20-30CM is a low silhouette VHF dipole antenna suitable for fixed site and shipboard applications. It provides excellent radiation diagrams and gain over the full 30-110 MHz frequency band.

Constructed from high strength glass/epoxy tubes with foamed-in -place elements, this antenna uses the standard CECOM 4-hole mounting base.

The antenna comprises two sections:- a base unit with integral lower element and an upper half dipole element. Positive screw locking attachments ensure very quick assembly with no tools required.

Covers entire tactical VHF Band with no tuning required
