Length & number of radials
 
If you are considering a new vertical antenna, instead of guesswork
and copying somebody else's un-thought-out efforts, download program
RADIAL_3 from website below.

The program assists with choosing an economic length and number of
shallow-buried ground radials. It takes a new look at how radials work
by considering them to be lossy, single-wire transmission lines,
open-circuit at the other end.

RADIAL_3 is a self contained file, 55 kilibytes. Easy to use. No
training needed. Download in a few seconds and run immediately.

Interesting program my Hustler 5-BTV installation with 72 buried radials
came out at 97.17% efficiency
Cool program.

=====================================
If the Hustler 5-BTV has any loading coils in it then its efficiency
will be less than 97%.

The program applies only to simple unloaded verticals which got into
the program only to illustrate how the radials affect efficiency.
