The baluN (not "balum") would go at the end of the parallel line closest to the shack.  Connect your coax there also (it's where the BALanced line meets the UNbalanced line).

I didn't find any manufacturer's instructions on the Internet (didn't look that hard), but do a search on G5RV antennas with Google.  Not every antenna sold as a "G5RV" really is one.  You can do as well, for a lot less money, by making a center-fed doublet that's a resonant length on 40 meters, feeding it with 60 feet or so of parallel line (ladder line, window line, whatever) through a tuner.

WIK:  "What's an RF supriser?"

Steve - for me it was a long time ago when my lips brushed the metal blast screen on my old mike.  Definitely a surprise!  Bit of antenna work fixed it, though ;>)

BTW, I took that question to mean "RF Suppressor".

I have the 102' version for trips with the Boy Scouts into the backcountry. I use an LDG Z-100 tuner on an FT-857D with battery/solar combination (no balun). The antenna is well constructed, and easy to raise between two trees. We usually get it up about 40-45'; it performs great on 20m, and gives us good service on 40m and 80m as well. It will load up on other bands, but current conditions don't allow me to do a proper evaluation. We have made quite a few 6m QSO's with it though. It is a bit heavy, so we do not use it for long distance backpacking, (simple long wire & couterpoise for those outings). I would recomend this antenna for quick, easy setup in backcountry terrain as long as you didn't need to carry it too far.
