- The DX Commander or other 10 meter glassfibre pole, fitted with a Loading Coil.
A 80M and 160M Vertical Antenna with a 9.68M driven element.
A base loaded DX Commander for use on 40/80/160M bands, with the use of the 40M element that's 1/4 wave on 40m (9.68M). The coil gives a very low angle of takeoff making it great for DX,
Please note: That the original DX Commander uses on 40m -11.15m (foldback back down pole ) and for this version some tuning is required by selecting the right turn on the coil.
This standalone version that can be.used with any glass fibre pole or bamboo Caine etc....
Thanks and acknowledgement to Roly - ZL1BQD for the original idea and also to Edy YC2YIZ whom inspired the stand-a-lone version.
80m Coil: 88 turns 2.5mm apart on a 76mm OSD PVC pipe. tapped at top and bottom, I used 1mm stainless rope about 20M long..
80m Coil: 25 turns 5mm apart on a 76mm OSD plastic pipe. tapped at top and bottom, I used 1.8mm enamel coated copper wire about 8.5M long from www.brocott.co.uk.
