Anyone used one and if so how did it compare to a 1/4 wave.



When I was in the Air Force the DDRR antenna became the topic of discussion
of many of us who were hams or wanted to become hams at the time. Someone
had read a little about it and decided this must be the end-all of antennas.
A little more research revealed that this antenna truly had a lot of the
attributes my friend claimed but it was also an extremely low impedance
antenna(less than an ohm if memory serves). This means the elements would
have to be built to handle high currents and the matching networks could be
a real problem. All of this meant lots of money to build so it was deemd
impratical.
