I have a number of M2 antennas and I have only had one problem. I called
them and they corrected it immediately by shipping the correct part. I
have difficulty believing they won't correct a mistake they made. I did
call them about mistakes in parts supplied with one of my 9 element 6 meter
beams, but it turned out I was misreading the directions and all the parts
were correct.
