If you want a good test, run it as a blind test>
Get yourself a two position switch and ask someone else to 
connect the coaxes from the two antennas to the switch, and 
simply number the
switch positions as 1 and 2.  Then run your tests without 
knowing which
antenna is connected to each position.  This blind procedure 
remove the personal bias that we have to our favorite or 
newest antenna.>>

In the 80's a few of my buddies on 75 meters kept slamming 
the thing. One fellow in particular was really slamming 
G5RV's all the time.

After modeling showed only a fraction of a dB difference on 
80 meters, I installed one. It was end-to-end with an 80 
meter dipole at 80-100 feet.

When I would test the antennas and say "G5RV" for the G5RV, 
it would lose to the dipole almost 100% of the time.

When I would say antenna A and antenna B, it was a virtual 
tie. No one knew the difference.

When I would call the G5RV a dipole and the dipole a G5RV, 
the G5RV (being called a dipole) would win hands down. The 
dipole, being called a G5RV, would almost never have an 
equal or better report.
