Help needed to identify 1.1 Balun

[Buick Mackane]

I know its 1.1 but is it a voltage Balun or Current ? Going by photos I've seen online I'm thinking its a current Balun ?

There is no DC short between the input or output terminals

It's a choke of sorts then I'd say.

Loads of vids on YT on chokes and baluns, one of l recall is called 'myth busting chokes and baluns' which l found informative.

Pretty sure its a current balun trans as a voltage balun would have a direct DC short between is input & output terminals

There's a lot of differing views on baluns and chokes, open, shorted, low resistance etc. Good luck fella.

Different ferrit makeup 'mix' for ithe intended frequency range use, coated wire to prevent arcing, good winding technique, low power saturation, minimum insertion loss, doesn't affect swr much when placed in-line, all the qualities of a good current balun slash choke.

A nano vna are good for checking baluns / chokes out

If l get some time to dig out I'll post a couple of pictures of a couple of baluns with my VNA connected to each.

Well i emailed the manufacturer if anybody should know what it is they certainly should

You would think so, but this is just me, l doubt what suppliers / manufacturers respond back with at times because it's been dependent on who within has responded - engineer / tech Vs a manager example.

Maybe another more experienced with member will jump in on this at some point for you.

Judging from other simlar photos of it seems to be a current type balun. Apparently a ferrite rod with windings and how it's terminated on the input and output is a voltage balun.

The manufacturer got back to me and as suspected its a 1.1 Current Balun

Sorted then.

Your post has reminded me that l have a FT240 / mix 43 core ferrite somewhere to make a CM choke / 1:1 balun up with. l bought a couple of baluns a while back and one is incorrectly labelled 1:1 when it's actually a 4:1, and the other turned out to be a voltage balun.

Sometimes making up your own bits of stuff is better than trusting in ready made bought stuff.
