AR270B 5.5/7.5 dB Dual Band Ringo
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 assemble with
three rugged aluminum tubing sections, a durable mast mount and factory
sealed coils for best performance.
