What are these called and where can I get one?

I'm looking for something like this:

I guess it's a "box" but that search term produces too many hits. I want to buy a dozen or so but the price of the above item is silly. Anyone know a cheap supplier?

You could try Newark Electronics. I know that they're a Pomona dealer.

Try to make them yourself and see what they cost you to build.

You might look to see what Keystone and H.H. Smith have

--but if you think there is much variation in price, you're dreaming.

Well it does look like I will have to make my own. Let's see, a little plastic box: $1, two bulkhead BNC jacks: $1.78 comes to a grand total of $2.78. Plus a pain in the butt driving around to get the parts. I can't believe these things retail for more than $5! I realize the Pomona part is probably weather-proof and so on, which is what they charge the big bucks for.

It's a metal box. RF Proof! And it can take the strain that a platic box can't. But, you're right, it is still too much. The only reason they cost that much is that there is little call for them now. I have a few in my junkbox.

Just think what what a PC would cost if they only sold a thousand a year.

ebay search for BNC bulkhead fittings, probably can get u 25 pieces for abt $10 total! ( or strip some from some surplus panels?)

(bulkhead fittings are easier to install, just drill a single hole, rather than precision laying out for those blasted tiny tiny 4/40 screws!)

ebay search for Bud Box or aluminum with sheet metal fasteners, probably get 10 for leass than $10

silicone sealer makes lotsa stuff waterresistant ( i never say watertight anymore, u just cant do it!)

if u want easy and lazy, spend money. if u want innovative and creative, GET BUSY!

Those special mounting screws are intended to use as grounds. Also, you can buy good quality Chassis mount BNC connectors with a single hole mount.

Great, unless you need proper shielding at VHF frequncies, and the oxides keep the flaps from making contious contact. They are not as well made, dent easy, and can even have connectors rip through the thin sheet metal when dropped.

for the bare, undrilled boxes.

It all depends on your application. If you're talking about frequencies below 500Mhz or so, you get all the parts you need at Radio Shack at reasonable prices. If you are looking for something that is bullet proof or using it for UHF or Microwave frequencies you'll need something more. I could give you a better idea of what to use if I knew what it was for. Promona's prices are high, but there are many more sources for what you want depending on use and environment. Bye Mike
