The original post is basically asking if 100 watts can be run from a
706 in a 60 meter mobile. The answer is YES. Why? Because an eight
feet long antenna is substantially less than the reference dipole.
[Typically it is -10dBd].


For a 10' whip, EZNEC says the radiation resistance
on 60m would be ~1.3 ohms. Doubling that for center-
loading yields ~2.6 ohms. Dividing by an estimated
feedpoint resistance of 20 ohms gives an efficiency
of about 13%. Assuming an efficiency of about 90% for
a 1/2WL dipole, I should be able to run
50w*90/13 = 346w. 100 watts should certainly be
justifiable. Heck, I might even fire up my SG-500
at 300 watts. Now the next question. Is anyone using
60m?


YEP!!! Quite active here in NE and along the East of the Mississippi River. It
is 1700Z and I'm listening to QSOs on 60-4 and 60-5 from SC and TN. BTW, I'm in NH.
