To further complicate matters, consider that the weight of the C31 listed in
F12's catalog is likely incorrect. They spec it at 82 lbs. I have built
two of them and they both arrived in two cartons weighing a total of 113lbs
for each antenna. Even allowing 10 lbs for the cardboard boxes, you end up
with an over 100 LB antenna. This results in a K-factor well over what
Yaesu spec.'s for the G-1000DXA.
For what it's worth I am turning a C31 and a MAG240N with a Yaesu G-2800DXA
that doesn't appear to be working very hard.
