Thank you Jazz. For certain there is more then one key function in the tapered coaxial basket. It's not 8 feet of elevation or magically increasing efficiency to some point beyond 100%. It is part transmission line, part radiator, part shield, tapered with a changing velocity factor and impedance. Sure are a lot of things to juggle in an attempt to reach maximum gain.


I also agree that this basket cleverly manipulates the use of CMC to produce it's second point of  in phase, correctly polarized radiation. It is also important that this basket maintain it's electrical 1/4 wavelength properties to effectively radiate this energy without causing undesired coax radiation.
