In my never-ending hunger for experiments, I made an experimental linear transponder from 144MHz to 2400MHz.
When I am at home the transponder is active and 2m stations in the vicinity of JO22OF can work over QO100.
Bandwidth of the transponder is 15KHz, theoretically 3 stations can work simultaneously.
Following the success of the Dualband feed designed by m0eyt, pa3fym and g0mjw, I decided to make one. With little more effort it was possible to fabricate all the parts for this antenna in larger quantities to support other builders. The parts are CNC fabricated to close tolerances.
