Should there be continuity when checking the wire connectors on the one side of the balun to the sma plug? i have no continuity thru the balun.

No continuity. This device is RF sensitive so won’t show anything. Be sure the ground wire is on the right side with the sma pointing forward.mine works fine on random wire 75ft long.

For we oldies which is gnd Very Specifically

the ground is on the right side of the green terminals. if you lay it flat with the words up the terminal at the top of the letters is ground

Of the two screw terminals for an antenna one is ground? Whis is which? There not labeled.

When looking at the Balun One Nine logo with the green connector pointing to the left, the bottom terminal is ground. Thank you for your interest!

Have the nooelec balun one nine v2 on a longwire and eton 750. i works well. do you sell a power amp that would work my this config for more stations?

We are very glad to hear you are liking the unit! Unfortunately we do not sell any power amps or power baluns at this time. However, if you are looking for an RX-only amp for HF, LaNA HF is a great choice and is available on Amazon. Thanks!
