Ham Radio: DX Commander Expedition pole, Roly Coil Mk2 - 80M Vertical. 

The DX Commander Expedition pole, Roly Coil Mk2 - 80M Vertical Antenna 9.68 Metres tall.
A base loaded DXpedition pole for use on 40/80M bands, with the use of the 40M element. The coil gives a very low angle of takeoff making it great for DX, add more taps for more bands greater flexibility...
Thanks and acknowledgement to Roly - ZL1BQD for all his help.
Coil: 50 turns 5mm apart on a 54mm OSD plastic pipe. tapped at turns 8,10 and 12 I used DX10 wire about 8M long. 16uH
Cheers
