The moral of the story is don't even think about going to the trouble of
putting up an MFJ/Cushcraft beam without taking apart all the traps and
fixing the above problems.
I have two very different takes on this. First, traps are an inefficient
way to build a multi-band antenna. That means they suck up gain. Also,
because the elements are shorter, their radiation efficiency is reduced.
The best multiband antennas don't use traps.
Second, buying ANYTHING from MFJ is probably a bad idea. I was VERY
disappointed when G0KSC farmed out the NA production of his smaller
antennas to MFJ a few years ago. I've been very impressed with his designs.
