TRI BAND 270A (TRIBAND)
TRI BAND (formerly our 270A) 2 METER / 220 / 440 flexible base loaded telescopic antenna is the standard for field use whether in the countryside or city. This super efficient VHF / UHF antenna provides a OMNI directional 3 to 9 db gain depending on position and is usable in 4 positions. (1/4 wave 2 Meter Fully extended) - (5/8 wave 440 2 sections down) (1/4 wave 440 fully collapsed) (1/4 wave 220 4 sections down) tuned coil/spring & available with any TA Base. This flex coil matching network provides at band center low SWR as well as a ± 5 MHz band center. Antenna tuned at 440 MHz being the band center, the antenna will perform the same between 435 - 445 MHz. Length Telescope 4.5" down and 21" up.
