Hi Tom.

I don't have a formula for you, but can tell you that I had good results 
with a double scalled version at 37 ft. in an inverted vee with the ends 
about 7 ft off the ground.  Worked well on everything except 10 meters, 
where it was deaf as a stone--a good 20 db down from listening to the same 
signal on an 80 meter dipole.   I used a one quarter watt beacon that was 
1.3 miles from my house for the comparison measurements on ten meters.

Anyway, it seemed like the inverted vee was a little easier to load than 
the flat top configuration.  The caveat of course would be that G5RV-type 
antennas are tricky antennas that are affected by a number of factors, so 
your mileage may vary!

73, de Lou K2LKK
