Appreciation post: That $80 Klein coax tester finally paid for itself today
Was on a rewire in an old apartment building in Tacoma, tracing a signal loss that was driving me nuts. The building's internal wiring was a mess of splitters and ancient cable. The tester pinpointed a corroded barrel connector behind a wall plate in unit 3B that my signal meter alone would have had me chasing for hours. What's your go-to piece of gear that seemed pricey but you'd never go without now?
