Amphenol Connex Adapter, BNC Jack To SMB Jack, Straight, PTFE Insulating Material, Brass Body, 50 Ohm Impedance, 4Hz Max Frequency

right here's another ham fest find this box here is a 16 channel video distribution amplifier mainly used in video surveillance and security systems that gives me 16 channels single video in and 4 channels out I can also be configured to be a single channel in with 8 channels out this basically unity gain buffer to distribute out to multiple video monitors now again I got it at a bargain price and my sole intention was to harvest the BNC connectors out of it so but before we do that we'd take a quick look at it maybe open it up and we'll also see if it works most RF systems that use BNC connectors are a 50 ohm impedance while most video systems that use the BNC s are 75 ohm now there are some physical differences between the two most notably with the insulator material around the center conductor with the 75 ohm often times it's a smaller diameter or sometimes non-existent at all notice
