i wonder how it would do in 60-70 MPH winds ?
"Finally, a mast mount version of the 11 meter "collinear" CB antenna is available. No other omni directional CB antenna can come
close to the gain of this antenna. Typically has 6 db (approx), over any other 5/8 wave antenna. It is designed to have extra long
range communications, due to its very low angle of radiation. Highest gain for any omni directional CB antenna made today. The
collinear pictured is literally "two" (hence double the gain of any 5/8th wave CB antenna made today). The 5/8th wave antenna
elements vertically phased and stacked on top of each other. Can often talk 100+ miles locally with this antenna, at 1 wavelength
(approx 36' above ground). This antenna is made out of a silver plated teflon heavy duty and high guage wire, and a silver plated coil,
to further enhance the gain of this vertical CB antenna. As far as gain, this omni directional CB antenna can keep up with a 3
element beam in all directions, with very similar gain!"
i'm always leery of big gain claims and when a omni is said to have the gain of a 3 element (or bigger) beam it usually gets my BS meter going . but i don't know anything about "collinear" antennas . i can't figure out where the feed-point on it is either . if it's on the bottom and they were compared at the same feed-point height the 50ft tip height advantage would seem to have a lot to do with their results ........ just guessing ......
