I'm planning on the same for a new tower install... get a larger plate of
1/4" 6061, and instead of Cushcrafts 8X8" plate, use a 13"VX 9H", go to
Harbor Freight and buy a set of transfer punches, transfer the 1/4" boom
holes centered, and drill the top/bottom holes for a 2" mast clamping set
of DXE super duty mast clamps. The XM-240 I received a week ago had a
tenacious black coating over the traps, but missed a few spots at the
connection of the wire to element, beware and reseal that exposed area if
need be.
