* Are your radials resonant? For the purposes that you are attempting,
they need to be, in order to maintain the phase relationship between the
driven element and the parasite.

Actually there are three cases that work:

1.) Where a limited size system has radials are exactly resonant

2.) Where the system is reasonably large, and because of size, has minimal (almost no) reactance contribution

3.) The small or resonant system is "tuned" to compensate ground system reactance out

All good topband ops know how to put up a beverage at night.
