Keith just made this comment and it sounds accurate. Ten feet is a bit low
for tuning. A 40 meter dipole tuned at 15-20 feet will resonate about 10-15
KHz higher at 78 feet.
Now lets change frequency to ten meters. A ten meter dipole antenna tuned at
15 ft would resonate about ( What ) KHz higher at say 75-78 feet?
Now lets change antenna to a 4 el yagi moving from/to same heights?
Thanks. 73 Mike N5MT
