[CQ-Contest] HyGain BN4000 Balun Question

[VE1DT]

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

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?
