What do you mean by "peak transmission time?" RF or power main?

You have never told me what frequencies you wish to hear. The best reception
would be with a 1/4 wave tall tower for any particular frequency. One
configuration that might work is to take half of a trapped dipole and suspend
it vertically, with the fed point near ground. The ground half of the
feedpoint would be a groundrod or buried radials - like they use in AM
broadcast stations. If the tower that suspends the antenna and the antenna
are grounded at the base with a good lightning arrester in the cable as it
enters your house you wouldn't have to worry too much about lightning either.
You would be able to use the grounded tower for multiple antennas - CB,
scanner, etc.

Buy a copy of the ARRL handbook. It's worth every penny!

Don't worry too much about service - if it hasn't broken by the end of the
warranty period, it probably won't break for many years. Most TV repair
shops would be willing to take on a reasonably made shortwave radio too.

Which state is that? Here in Minnesota we still have only a trace on the
ground. Most places are still bare. And we have some pretty darn good size
trees around here too.
Merry Christmas to you (- and Happy Hannukah to our Jewish friends!)...
