booty,

i never noticed any rfi problems with the sigma style even without a  choke at the feedpoint but i do have a significant run of coax laying on the ground,

i dont doubt what shockwave claims but i cannot confirm it with current measurements at the moment,

im sure you have read what i claim for the sigma hybrid vs 5/8wave before and i stand by what i claim 100%,


shockwave,

glad to hear you are making progress, i understand the 5/8wave is less work and expense than converting the sigma style using a quality gamma and connector,

you will not be getting any competition from any individual this side of the pond as materials are far more expensive over here, it would need somebody with the bulk buying power of sirio to make such an antenna viable,

its catch22 because the guys that can obtain decent tube at relatively inexpensive usa prices dont believe in the sigma style antennas capabilities, nobody gets the opportunity to buy a sturdy built best performer.
