The ATAS-25 utilizes a manual tuning system which resonates the radiating element for lowest SWR without the need for expensive, inconvenient mono-band resonating whip assemblies. The ATAS-25 allows dual-frequency operation (on HF or 50 MHz
and either 144 or 430 MHz), if two transceivers are combined via a suitable diplexer (not supplied). The ATAS-25 is designed to mount directly onto a standard camera tripod (not supplied)
