Presumably, the reference antennas against which the G5RV is
called a "compromise" are full-sized dipoles for the respective

Of course they can!


Reg, I just modeled the half-sized G5RV using EZNEC.
The dipole is 3/2WL on 10m and the twinlead is 1/2WL
on 10m. EZNEC reports the following 50 ohm SWRs at
the twinlead/coax junction.

10m - 2.0:1, 20m - 2.7:1, 40m - 2.6:11

I would be hard pressed to tell the difference between
the efficiency of a half-sized G5RV vs a resonant
dipole for those three bands.
