It is not being used as a choke, it is being used as an Inductor to help match the feedpoint of the antenna.









Again :




The Matching network is used to match the feedline to the antenna at the feedpoint, while the length of the antenna is at the true resonance point.

  Even more important when the antenna is NOT a 1/4 wave......anyone one remember the discussion about the Dave made " Rod Of God Antenna"?

It was a 1/2 wave, and as such the 1/2 wave is at high impedance at the feedpoint so it needs a matching network.

Back to the 1/4 wave, it is close already at 11 meters so (as Eddie has already pointed to) is there any advantage adding the matching network at the feedpoint when there can be small losses in the matching network itself ?




I agree with you.
