Looks like it takes bird 43 elements. And can do forward and reflected at the same time.

But what type of connectors does it use for the meter movement?

That is a N-Type line section You put the slug in the side and hook the bird movement to it with a cable.

Thanks for the link NJ 124. The connectors I was asking about are for the meter. His site referes to them as "DC" connectors. I'll need a couple of those too.

That's the connectors I was looking for. Kind of pricey though. According to Henry's website they are BIRD propriety(sp) so I guess that why they cost so much.

Uh huh. Get yourself a regular connector with the same collar size. Cut the center pin down.

Heath used to use that connector on their test equipment too.

Uh, Toll, you don't mean this one, do you?

I think Amphenol's number was 80-MC. Used on every high-school PA system until 1965 or so, when they figured out low-Z mikes are better with a long cable on them.

First thing I ever built that was any good was a Knight-Kit VTVM, used this socket for the DC probe. Heath's VTVMs did, too. Changed all mine to 1/4-in. phone plugs before long.

This plug works to sub the Bird "DC" plug only with a LARGE bump of solder on the center hole. Kinda flaky, once the solder gets pushed down and starts to tarnish. The PL-259 idea with the center pin ground nearly off is more solid.

Hosfelt Electronics has the plug above for 99 cents. It's their pic, too. Their stock number is "MC1". You decide how much trouble it is to adapt one of these, in place of the Bird proprietary plug. If your line section is mounted with clearance around it, this works okay. If your line section is mounted in a model 43 case, you need the low-profile right-angle "Bird" plug. A substitute won't fit.
