Which meter did you buy? What did it run
you?

Get a test meter. I got one from BVS Systems and LOVE it
! Roger Peters has had great piggies in the past. I just tested a
UFL from Wisp-Router and it was 2 dB better than anything else (UFL) I have
tried, but it was only 5" long, so I am sure that has something to do with the
better "review". Once you have tested a few radio cards and pigtails
with this meter, you will wonder how you ever lived without it.

As to
what is wrong with them, I don't know. I do know that the ones I
tested and published to the list were all new units. They
were opened
fresh for this test. I tested some other units as well, but I
felt that
it made more sense to show the results from new, 'identical'
pigtails....
I plan to buy sets of pigtails from other manufactures
and continue to
test as I have time...
