The ATAS-25 utilises a manual tuning system which resonates the radiating element for lowest SWR without the need for expensive mono-band resonating whip assemblies. It allows dual frequency operation on HF or 50MHz and either 2m or 70cm (duplexer not supplied). A very handy feature is that the ATAS-25 is designed to mount directly onto a standard camera tripod mount (not supplied) and makes up a portable antenna system ideal for tempory field operation but not recommended for long-term outdoor installation.
