Topband: Inverted L Question

Given that you have the 70-90 vertical rise as a given (not in play as
maybe or maybe not), what the shape of your L will do to
improve/worsen your signal will be overwhelmingly swamped (not close
at all) by what you do or don't with your counterpoise. Unintended
coupling of lossy ground by a dozen different unfortunate counterpoise
issues have resulted in installations with as much as 15 dB gone to
ground losses.

Tell us about what you intend to do for a counterpoise.  Radials?
Buried, elevated?  How many? How long?  Miscellaneous length and angle
according to opportune support?  Uniform in length and angular
distribution?  How high above ground?

Those will determine how well you get out.

73, Guy.
