Hi Fred,

Yes.... sorry for not being more specific, radius. I can go out farther but
then it's up in my yard where I mow pretty low. The 5BTV is ~24 feet
tall.... I have heard this formula for radials before.... but, is it really
meant actual "physical" height of the radiator and traps or is it really
meant to be the theoretical electrical length (height) of the radiator ?

From page 20.20 of my Arrl 2000 Handbook: "...a large number of
shorter radials offers a better ground system than a few longer ones.
For example, 8 radials of 1/8 wavelength are preferred over 4 radials
of 1/4 wavelength. If the physical height of the vertical is 1/8
wavelength, the radial wires should be of the same length and
dispersed uniformly from the base."

And... I got the antenna and mounting/radial system from DX Engineering.
