DX Commander Antenna Build




  How to build a multi-band HF Vertical Antenna - DX Commander Rapide
  You can build this ham radio antenna - or you can build mine from a kit?!
  Based on a 7m telescopic pole and will work from 40m through to 2m band.

  Cut Chart as follows. Cut your elements this long:

 30m 7.99 (includes 2 x 6cm loops and a 1.29m return off the top)
 20m 4.95 (all these have a 6cm loop incorporated into this cut chart)
 17m 3.85
 15m 3.29
 12m 2.81
 10m 2.50

 To clarify: Taking the 10m band for instance, cut your element at 2.50m exactly and fold-back a loop of 6cm which makes the new total length of 2.44m.
