[Elecraft] Strong recommendation: MFJ 18xx-series single-band whips for KX3, etc.

Since folks are talking adding a top hat or base loading coil, why 
not just extend the length of the vertical to a full 1/4 
wavelength?  1/4WL = 248/50.1 MHz = 4.95 feet (59, 3/8-inch).

Connect a small alligator clip to a 11-inch piece of hookup wire and 
suspend the wire with a piece of cord to "something", OR uses heavier 
stiff wire that will self-support.

Now you have a resonant 1/4 wave vertical.

OR buy a 5/8 wave base-loaded 2m mobile whip - loads on 50-MHz very 
nicely.  That's an old trick for dual-band 6m/2m use.  Try brands 
like Larsen or Maxrad.
