The export controls still exist, by the way, for NEC4.. when you get a
copy, don't you have to certify who the end user is? and agree to ITAR
compliance, etc.

Until a few years ago, NEC-4 could only purchased by a U.S. citizen for
use within the U.S. Anyone else would have to apply for an exception via
diplomatic channels.

Now, there are no restrictions except for a very few prohibited
countries (e.g., North Korea). Licenses are routinely granted for users
all over the world. The program is, however, still protected by copyright.

Buried antennas were seriously investigated by the military some time
ago, and are probably still in use. While terribly inefficient, some can
radiate enough to be useful, and invisibility can be an asset.

Agree.

I didn't mean to imply that a buried antenna wouldn't work at all. Dirt's
not a perfect shield material, which is what would be required for zero
radiation.

How about in a dry sandy desert?

antenna you had? I wonder if one were to make a longer version would it
have gain & a wider bandwidth?

Just remember the general rule for antennas: small - efficient -
broadband: pick any two.

Methinks you forgot inexpensive. Still pick any two.

Frankly, I have wondered about this. If I hooked an antenna up to my
dummy load, how far could I transmit? What kind of kilowatt signals
would be able to move my meter needle?

Or, was that only a dream? grin
