I read what you said about the 90 ohm load resistors built into the DB224
and will have to disagree with you. I have worked on many DB224 antennas and
modified several and I can assure you there is no 90 ohm load resistors built
into the harness. The harness is built of several values of coax to match the
100 ohm folded dipoles to a 50 ohm feedline. I suspect you will hear from
others who also know better. I can safely tell you this is about the best
antenna design I have ever worked with.
