Hi Skipp

Using coaxial-type and have tried both the coax and
solid screen by way of solid copper sleeving over
centerwith dielectric from rg-213.

My question is that there seems to be very different
thoughts on the first element-some use 1/4 and others
use 1/2.
Every article-design seems to state that there antenna
works well or better than antenna  X or Y.
Of all the designs none have substantiated the design
with an analyser of any kind -all are going on only
VSWR readings.Good VSWR does not mean good antenna .

Kind regards
