[Elecraft] [k3] Isotropic Antenna

[Alan Bloom]

Years ago, a local ham who was acting as an Isotron distributor brought 
the 80 meter version to the club's Field Day.  I discovered I got out a 
lot better by unscrewing the shield of the coax connector and just using 
the feedline as an antenna.  :=)
