75, I agree with your Choke location on your Imax.

I know this is off the subject for this thread, but Timmy was talking about the issues with RF chokes. snippits75 talked about his using a choke 8.5' below his antenna.

Note: some antennas require a different location on the feed line and that is the point I might raise here for further discussion.

Below is my model of the Imax without the mast being isolated, also with and without the choke 8.5"or >...below the bottom of the antenna.

Abbreviations defined in the antenna title.
wC47pF - with Imax capacitor near the middle of the radiator at 47pF.
wC - with CMC choke in the middle of the radiator and is marked with an underscore____.
wTF - with transformer at the base of the radiator for matching.
nRs - with no radials
