My results have been mixed. When they work, they're fine. I have five
1x4s. I One came with a mfg defect that made the #4 position not work,
and it could not have made it through final test if there was a final
test, so there must have not been a final test. :) I have another that
went bad, again with a position that doesn't work. 40% failure rate puts
them in MFJ territory. :) On the other hand, when they do work, the
signal path is good enough for 2M. Maybe even on 440 -- haven't measured
it carefully.
