Phil's "The 43-Foot Vertical" presentation is very well written and
contains a wealth of good information.

Phil references a 10 Ohm ground. Using the information in:
http://www.kn5l.net/GroundRadialStudy/
which summarizes three published ground radial analysis reports. Using
the combined data from the three reports:

A 160 meter radial system requires 24 80 foot radials for a 9 ohm ground.

A 40 meter, and higher frequency, radial system requires 60 56 foot
radials for an 8 Ohm ground.

Both assuming an average ground.
