I am involved in an experiment on what appears to be a new type of vertical antenna. I can't tell you what it is at this time
What I'm interested in is MEASURED 2.0:1 VSWR bandwidth from 1/4 wave verticals that have enought radials attached to all-but-eliminate ground losses from the data. And/Or similar data from elevated verticals with radials.
I'm most interested in 10M and 15 M but any information will be useful.
Please note I am NOT interested in techniques to improve vertical efficiency, info on qty of radials vs efficiency, elevated vs ground radials etc. ONLY bandwidth of real 1/4 wave antennas.
Several prototypes of my new design are showing what appear to be unusually large bandwidths that are NOT due to matching network losses nor to ground losses. So I want to learn "how good is it?" when compared with a standard 1/4 wave antenna. And I can't find any info in the literature that I have, nor online, on bandwidth.
Thanks es 73!
