Cushcraft AR 270B, 2 Meter Dual Band Vertical Amateur Radio Antenna
This model gives very high gain with a low angle of radiation and it is only 7.7 feet(2.35m) high. The AR270B is computer optimized with two 5/8 wavelength collinear elements on 2 meters and four 5/8 wavelengths on 70 cm. It is broadbanded for minimum SWR on both bands. It is easy to asseble with three rugged aluminum tubing sections, a durable mast mount and factory sealed coils for best performance.
