[Elecraft] Elecraft. G5RV Question

[Steve Hostetler]

Leigh,
My doublets work great on the higher bands.  In theory, the lobe 
configuration does changes with wavelength n of the wire, so you have 
roughly 2n lobes.  But you also get some gain, and, more importantly, a 
lower peak angle of radiation.  You can read all about it in W4RNL's 
great write up:
