Richard Fry in a private e-mail noted that I had misquoted E. A. Laport
who wrote:
"---it is desirable to employ complementary antennas for transmitting
and receiving."

I typed "complimentary" which means praise or a gift. Surely Laport
meant antennas which work together to perfection which is even better
than getting them free. I made a typo.

I apologize for my mistake.
