Covering the VHF frequency band 108 to 152 MHz, the 20-20-100 is a lightweight antenna intended for ground and shipboard use.
Construction uses an advanced GRP encased radiating element bonded into a machined aluminum base, suitable for prolonged use in a marine shipboard environment.
Unique design ensures good elevation pattern throughout the frequency band and passive matching housed within the base maintains VSWR within 2.0:1 and provides exceptional gain for such a small overall structure.
