[Lowfer] The Lowfer antenna

[Ashlock,William]

Hi Tom,

Thank you for your timely input. Nice to see such a clear statement of what
the Lowfer transmitting strategy should be all about. We should all post
this on the wall!

Since I began striving for, as you say, "the maximum current over then
length of the conductor" all the unknowns began to go away. Some of my
original work was trying to maximize the voltage on the antenna and, now, I
realize the voltage is just a byproduct of the current. TX loop antennas
exemplify this to a tee.

One additional parameter I think that is worth putting on your list is
losses from capacity coupled objects near the monopole antenna such as
trees. Because of the hi-Z on the upper portions, just a few pfs is all that
is needed to raise the total system AC resisitance out of site. Often this
looks like an earth loss but adding no amount of copper under the antenna
will make it go away.

Regards,
Bill Ashlock
