This question is directed to anyone who can answer it but specifically to ka3jjz.
Mike, earlier in my mil-air post (before it went off topic, sorry, I didn't even realize it should have been in the antenna forum) you told me about an idea when building the ground-plane antenna. you said,
"In fact, let me throw something else out here - you can make the ground plane dual band by cutting one vertical element for one set of freqs (say 140 mhz - which will put you right in the middle of the 138-144 milair band, where many air national guards hang out...) another vertical element for 300 mhz or so. Cut the radials 5% longer than the 140 mhz element and you should be good to go."
How do I put two vertical elements in one so239 socket?? Anyone have pictures of how this is done that I can see whatt I should be doing...
