Check out the OM himself in 'The G5RV Multiband Antenna... Up-to-Date' at:http://www.arrl.org/members-only/tis/info/pdf/acv1086.pdf
Quote: "The main reason for not employing a balun in
the G5RV... the balun cannot compensate for the
reactive load... whereas a suitable type of matching
network can do this most effectively and efficiently'.
The G5RV (and half-sized and double-sized) must be
used with a Tuner (i.e. Antenna Match). You will need
a choke, not a balun, at the COAX-To-Parallel
interface to reduce RF from the outer side of the
coax. This is easy - you can just wind some coax like
you would a coil of rope - about 10 to 12 inches in
I recently redid mine to tidy it up a bit - as you can
also wind a few feet on a one foot section of 4 inch
or 8 inch diameter PVC. Works pretty much the same.
I use a half-sized (52') G5RV and I just got my
farthest contact so far in Northwest Italy from
Dallas, Texas with 100 watts.
