Do any of you know anything about the RLM Electronics MN100-1 broadband HF
antenna matching network? (see
http://www.rlm-electronics.com.)
It looks like the same general idea as the T2FD antenna except the
terminating resistor is in the box with the matching transformer.
They claim that the "four non-inductive balancing resistors" ("balancing"
resistors?) will dissipate no more than 3 watts each with 150 watts of RF
drive, which if true (big "if") would seem to indicate an overall
efficiency somewhat better than a T2FD.
Gee, maybe there is such a thing as a free lunch. :-)
