[Elecraft] OCF antennas

[Rick Dettinger]

Probably the most elegant solution is to actually change the physical  
length of the element(s).  Mike, KK5F, does that with jumpers on his  
portable dipole, and SteppIR does it by spooling up the un-wanted  
portion of the element.  There was a design in QST that used air  
pressure to operate relays that accomplished the same thing.  Maybe,  
this could also be done with relays powered by the signal.
