RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling

Carl Concelman of Amphenol, the TNC connector has been employed in a
wide range of radio and wired applications.

Reverse Polarity (RP)
connectors. Reverse polarity is a keying system accomplished with
a reverse interface, and ensures that reverse polarity interface connectors
do not mate with standard interface connectors. Most manufactures accomplish
this by inserting female contacts into plugs and male contacts into
jacks. Other manufacturers use reverse threading to accomplish reverse
