Protect Your Transmitter Site Phone Line? RW rip.

FWR'ed from Boomer. Not only could this protect landline phones from getting ZZZZZZZZZZZZZZAPPED at tower site locations, but could help take out RFI from close AM TX sites, or if you have a Carrier-Current station on-site. I wouldn't use this for Ethernet connections, unless you want a really slow BIT Rate.

The best two statements of advice that I've ever gotten are from my brother-in-law in the early 1990's. 1st one, when I bought a used '89 Olds Cutless, my bro-in-law said, "Congratulations!!! You've just bought a deficit!". The other, was on a work environment, " No matter where you go, it's going to be f***'ed -up!". No truer words have been spoken.

The Crown Amplifier Guide found at the link is a good resource.
