I fully agree, but we have absolutely no input in regards to the mast
they have provided, and to attempt to persuade them otherwise would only
jeopardize the situaion, so we must accept what they have provided and work
with it.

There is someone, somewhere, who has the authority to
change the mast from aluminum to fiberglass for the
purpose of multiplying your radiation efficiency by
a factor of 7. I would seek that person out and bend
his/her ear.
