Thanks again for various comments.
1) Amp-Metres this is of course understood,but
it is not significant since the currents will be adjusted to obtain equal powers
in the two ants.
2)Dave ZL3FJ is concerned about co-siting and
mutual coupling.I agree but it should be possible to de-tune the big ant. and so
long as they are not too close I dont think the mutual will be very
significant.However the two ants. could be on separate sites since even the
professional ground is not likely to be all that good.
3) Mike G3XDV states that with practical levels
of ground loss the lowest angles of radiation are attenuated more on very short
verticals than on long ones,OK but 300Ft is still a very short vertical (it
would need to be more than 500M long! to be quarter wavelength) So I doubt if
there will be ang great difference between 300 and 60 feet from this
cause.
So I still think this a worthwile experiment.
