Trouble Brewing

Sitting in my office is a device* that is just begging to be abused.

Click for a closer look

In this era of  'If you see something, say something', do you think this device, left in the front seat of a car parked, say, at an airport, might get noticed?

(The tennis ball cannon in the corner is another device needing some attention, but that can wait a bit... I actually have a legitimate use for that beast.)

*What is it?  Go ahead and take a guess.
 RobertaX might know what it is, but since she only reads this foolscap on a passing basis, she probably won't tell you...)

Looks like a repeater can for some type of RF system.

A Keg of nice fine home brewed ale?

Well, not quite a tuner but does in not act something like a check valve by not letting the RX and TX mix?

It's a hot water heater!

No wait! It's an espresso machine!

It's the cavitation that does the damage, Officer.... ;)

Y'need some curly, curly wires, not LMR-240 or RG-8.

PS: 2 meters?

Close- got the RF part correct.

There was a suggestion to use it as part of a column still... But no.

Closer and closer...

+100 for the True Lies reference!

Yes... That was my plan-
Some nice curly wires, perhaps pick up and old school beeper or antique cell phone and some other esoteric 'scary' circuit boardage and wire it all up...

So- commonly known as a bandpass filter, used to filter specific frequencies and reject (attenuate) any others. We use (well, used) them with on old RF-based scoring system...
Since we have gone mesh wifi now, these babies are of no use, except to monkey-wrenchers like Yours Truly... ;)

(Although turning them into column stills has merit... That, or fill 'em with rocket fuel and strap them to the side of my bike as ersatz JATO bottles.)

And @RX:
450-470, currently tuned to 464.625

It is the thing from "no country for old men"... a cattle killer..

Old NFO said...

LOL, I'll take half credit for a stab in the dark...

It is a Band Pass Filter (aka Pony Keg) used to connect a Telxon Base Station to a Omni Directional Antenna. Based on the size of that Keg, it is probably 496.50 MHz frequency.

That's part of a set of duplexer cans, I'd guess in the 150-159 range.

Oh, this was before I read the other comments. I've seen smaller cans, ahem, for UHF.

The last set I worked on had six of those, all copper, heavier than hell.
