providing a frequency coverage of 2 to 30mhz, the barrett 910 features rapid tuning (typically <1.5s) and low power consumption. high radiation efficiency and accurate tuning are assured by maximising antenna current (not minimising the vswr) on every tune. the barrett 910 antenna incorporates a wideband amplifier that is activated in receive mode to enable channel scanning. due to its rugged rf design the barrett 910 antenna can also be used with high duty cycle applications such as the barrett 923 or 2020 fax and data system.
the active tuning elements of the antenna are housed in a grey weatherproof, impact resistant reinforced poly-carbonate moulding that incorporates a heavy duty anti-vibration mount at its base, even with its rugged construction, the barrett 910 weighs only 2.8kg.
the barrett 910 is supplied with an integral 2 metre whip and spring. the main antenna body has a 1.5 metre stub control cable, with a 4.5 metre extension cable to connect it with the transceiver. this composite cable incorporates coaxial, power supply and control cables. additional 4.5 metre or 10 metre extension cables are available if required.
