You bring up an interesting point.  Periodically, at different locations 
around the country, there is something called a mobile shoot-out.  The
mobile operators gather and run antenna tests with their various 
mobile antenna types.  I think they use a common wattmeter to 
set the power level to a common level and fixed locations for the 
source and receiver/measuring unit.  

It would seem to me their results might be somewhat consistent. 

Why could something similar not be done at some of the larger 
contest stations which may have a variety of different antennas?  
Where some popular antennas are missing, maybe they could 
be made available from club members or even the manufacturers 

Heck, I've heard of some clubs on the east coast that have upwards
of a couple of hundred members.  It would seem to me that at any
one time, there would be a couple of different beam antennas on 
the ground for one reason or another and might lend themselves
to being placed on reference tower and applied with a reference
power level and received at a reference site with a reference antenna,
reference receiver, and reference measuring and recording device.

That would be very interesting.....
