Will this cabling idea work?

Not cheap? 2 gold plated parts for $5 or a bag of 10 without gold for $5? Sorry, that's a level of poverty I haven't been exposed to before. You have my respect.

Those "F" connectors are not cheap in small quantities, and I have not seen the others at that price around here, at least, in quite a while.
And it seems that what is "cheap" varies quite a bit among us. I am aware that the cable company buys them by the thousands, but I do not.

The link was Amazon, Buddy. No multi-dozen or thousands order there.

I got some F connectors on eBay a couple years ago like I remember from the 60s. Just a machined nut and an inner part that slid down between the braid and the outer insulation, maybe a C-ring to hold it in place. They always worked adequately, we used to squirt them full of silicon grease if they were going outdoors, and snugged them up with a (7/16?) wrench. Something like 20 cents each. They were strictly for RG-59. No gold plating, which is only good if the mating parts are gold plated..

RCA plugs are hard to find in the old style too. Every TV chassis had a chunk of coax coming up from the IF strip with a soldered-on RCA plug that plugged into the tuner. They were so standard there were tuner substitution boxes, I think a solid state tuner with a 9 volt battery or two. I always cut those off and saved them before the TV went to the dump. Very simple, a hollow pin you soldered the coax center lead into, a bakelight insulator, outer tabs that were just bent sheet metal. With much use you'd need to give the tabs a squeeze with piers ("retension") or the ground connection would be flaky. Aliexpress is maybe the wrong place to look, I'd settle for some new old stock American ones from eBay, but I wouldn't spend much over 20 cents for those either.

Not sure what I'll use for connectors since we're mixing RF coax and audio wiring. Still waiting on better electret capsules from England and better transistors from China. Recorded my first thunderstorm the other day, peaks are way too loud and clipped, which I sort of expected. Sox can do a normalize but I don't think there's any magic to it. Ideally I'd like to have it store 32 bit data with plenty of headroom in a buffer, then shrink it down to 16 bit to write out. My 16-bit half hour files are about 300 MB each, 32-bit ones are double that.

Thinking of microphone roofs and wind screens. I want to test a stainless Chore Boy (pot scrubbing thing) as a wind screen because I want it to stay out there semi-permanently. For a roof I'm thinking of cutting up some kind of ball. With a flat roof each drop makes a big impact noise, I think if they hit a convex surface they'll dissipate better. There's noise-reducing covering for metal roofing that's like that plastic scotch-brite green scrubby pads, not sure about standing up to sunlight.

48-hour power outage, just getting things going again. 18650 cells and LED lights are a big improvement over car batteries and 12-volt CFLs. I had a fully charged car battery and a 4-cell charger that runs from 12 volts for the 18650 cells, it's always been flaky. Finally realized I've got a 2.5 mm ID plug on the cable where it should be a 2.1. Only works if you wiggle it right. No 12 volt soldering stuff, I only think about these things when the power's out. All my 5 volt stuff (phone, mp3 player, laptop) had dead batteries because I had no way to get from 12 volts to 5 rigged up.

But I just voted, trudged back up to the mailbox with it.
