The actual measurement of a slinky antenna---necessary to guarantee
optimum performance---- would be simple.
Wouldn't it be nice, if BEFORE someone sold something...or told
someone else how to do something..... they would have taken a few
hours to make a few very simple tests so the customer got the best
product possible???
I offered to do that for free, and my offer was refused with more
personal insults. Think about that..and re-read the posts carefully.
If your read, you will see I never said they wouldn't work...or would
work. I simply said it was unlikely someone could just make a
wild guess and "land" on the optimum values.
I am guilty of trying to explain WHY the surge impedance is most
likely nothing like a Beverage, and probably should be measured.
And I'm guilty of suggesting it wouldn't be a bad idea to measure the
phase delay through the antenna, so a person would have some basic
idea of how far the thing needs to be stretched for best performance.
In hindsight, I wish I'd have never said anything. The days of people
wanting to understand how things work or having them work as
well as possible are probably about over.
10-4?
