Putting up a vertical antenna part 2 – The plan

img_20161008_145654So the plan is the following:

  • Two radiating elements will be added for 10 and 20m. The elements will have a length of appx. 2.60 and 5.20m. The exact length will be determined by my antenna analyser.
  • The main element will be adjusted to length for 15 and 40m. This -should- already be done, but because every situation is different i just want to check and re-check. Just in case.
  • 2 sets of 4 radials will be added for the 10, 15, 20 and 40m bands.
  • The antenna will be hooked up to a common mode choke built around a FT240-031 core according to the design from DG0SA.


Bought some stuff this morning in the local DIY shop and first thing i’m going to build is the choke.
