SMA finger-tightening tool - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Can anybody identify the manufacturer of this tool?

It's a special tool for tightening SMA connectors.

The http://www.ni.com/communications is just advertising.
I have contacted NI and they don't know.

Pulse Research Labs has a finely machined product called SMA finger wrench

I have a couple of those plastic SMA connector tighteners down in the lab. I think they are trade show props for handing out to visitors. Don't recall seeing a manufacturer name on them - just the name of the company who paid for the promo. A quick Google Search didn't turn up anything either. You'd think they would be east to find.

Greetings:

UPDATE 4/17/2014: Bracke Manufacturing now offers an SMA Finger Wrench!

Like a lot of people, I have one of those plastic SMA tools as well, but mine says Agilent on it, and they don't make them either. I sent an e-mail to LeCroy to see where they get the ones they include with a couple of their instruments. No reply thus far.

All-around good guy Bob Davis sent me a link for another type of SMA connector tool that someone might be interested in. It is made by a company called Mountz.

Other sizes are available as well.

Speaking of SMA connectors, take a look at the spacing of the ones on this new SP5T RF switch by Narda Microwave East. Note that the adjoining sides of the connector flanges share a mounting screw where the ends have been milled off. Now that is tight spacing!
