Jim,
The BN-4000 manual says the balun is just a string of beads over coax.
Ohmmeter should work fine.
"The BN4000 uses ferrite beads over a short length of coax cable to
choke-off the flow of RF on the outside of the coax shield."

[CQ-Contest] HyGain BN4000 Balun Question
from [Jim George] [Permanent Link][Original]
List-post: <cq-contest@contesting.com">mailto:cq-contest@contesting.com>
We will almost certainly be replacing a HyGain BN4000 one-to-one balun here
shortly with a WX0B one-to-one balun. It is important to get the "center
conductor" connected to the same half-element of the driven element in
order to maintain polarity and phase in a stacked yagi system of 205CAs.
Can one use an Ohmmeter to check which output lead of a BN4000 goes to the
center conductor of the PL259 and which lead to the shield?
