strange eh mack, i doubt even you could pull this one off:blink:

shockwave,

your claims bear some striking similarities to what i see in my own tests, i almost fell off my chair when i read your post, remote viewer?,hoax?,i dont know,
but,
im still not sure exactly how the lower 1/4wave is working, i cannot get away from the modified skleton sleeve antenna idea untill i have made current and field strength measurements, the rest of your claims are spooky, like you have been watching me for years,

i owned the original sigma4 and the big-mac at the same time and did comparisons,
mounted at 73ft to feedpoint in a field the big-mac had the edge but it also had an unusual character,
as it swayed in the wind it would make me look like i was mobile to anybody watching my signal and the same effect on my receive, even though the big-mac did flex more than the sigma it gave me the impression that it had a very narrow vertical beamwidth which only outdid the sigma when it was dead calm,
i think but cannot prove that the vector tuned correctly is far enough in front of the sigma to put it right with if not slightly in front of the big-mac without the seemingly very narrow vertical beamwidth,

when you look at the simplicity of the sigma design compared to the monster big-mac, far fewer feet of tubing, its much smaller footprint and its ability to perform at low heights/poor surroundings or mounted high above the ground without any notable strange characteristics its clear the avanti guys were at the top of the cb antenna tree back then,
some have copied the idea and in the case of the extended 4 radial version improved the design in performance but not structural integrity, some as my old man would say "they cant see the forrest for the trees"

when i put the sigma/vector hybrid back up i will be experimenting with radial length and hoop diameter, i expect to see the extra gain that avanti mention in the patent,

cebic told me the sigma style antenna would be very difficult to accurately model,

j-pole? definately not, build one test one, you will see.

thanks for the interesting read, if its a windup its top class.
