How does one determine the spacing between a gamma match and the main antenna conductor? As in, where they're parallel between the two feed point terminals. :/ #AmateurRadio #HamRadio
Without doing any modelling, I would say it's probably not critical and it's likely to be a small fraction of a wavelength at the relevant frequency. I suspect it would just adjust where the gamma match attaches to the driven element, similar to, eg a J Pole feed point.
Of course, the correct way to answer this is to post a picture to QRZ.com and wait for 40 different "you're doing it wrong" posts that reference ARRL handbooks from the '40s
