A full size 3L40 on a 48 ft boom would make a good candidate
for a matched boom antenna for 80M. A tribander on a 31 ft
boom is pretty small. It possibly could be done but the BW
will be very narrow and efficiency questionable.
Besides, aren't the elements of the C31XR also insulated
from the boom?
