M0CVO HW-80HP Multiband HF Antenna 80-10

The HW-80HP is an Off Centre Fed Dipole designed to operate on 80m (3.5MHz), 40m (7MHz), 20m (14MHz) and 10m (28MHz) without an ATU and 60m(5MHz), 15m(21MHz) and WARC Bands with an ATU. Having a feedpoint at 1/3 of the way along instead of halfway along gives a feedpoint impedance of 200 Ω . This is not ideal for modern day transceivers requiring an antenna with a 50 Ω impedance. Therefore, a 4:1 current balun is added at the feedpoint to alter the impedance to something closer to the 50Ω required. This then allows the antenna to be fed using standard 50Ω coaxial cable such as RG8 or RG213.
