With TV stations shifting to digital, how would a surplus analog
video distribution amplifier do?
There should be a lot of high end amplifiers made by Grass Valley
(Tektronix) available soon.
These are used in a frame. The input loops through the frame. Each
amplifier has 6 isolated outputs. Depending on the amplifier, you
might have control over the equalization or not. All that I have seen
allow the amplifier gain to be adjusted from the front of the module.
