This antenna covers all bands (including WARC bands) from 80-6m, 5W guaranteed, 25W max. When fully telescoped it is 1.65m long approx. It is fitted with a 3/8in connector but is also supplied with tthree adaptors 3/8in to PL-259, 3/8in to BNC and RA SO-239 - PL-259. This makes it ideal for the FT-817ND or any other portable low power HF radio. Band changing is achieved by plugging in the "wander lead" into the appropriate socket on the base coil, and fine tuning adjustments are made using the 10 section terlescopic whip. The whip unscrews from the base matching coil so that packed down, the antenna only measures 32cm.
