Chris, that's got to be a really old video distribution amplifier. I was
just given a thin rack-mount video distribution amplifier with ten
outputs and the specification says 300 MHz bandwidth at 3 dB. I have not
measured its output level. It is made by Kramer and has BNC and S-video
in/out but no RCA composite video connectors. Well, that's the published
spec; I have not tested it on my Tek 2712.
We are not talking about critical phase relationships, just distributing
10 MHz for sig generators and counters.

I think people have used video amps. I got one recently for nearly
zero cost and it works as spec'd but video signals are typically 1
volt peak to peak and the amp is spec'd for "10MHz, 1dB" which means
I'm right at the limit and I'm a 1 dB down, just as the spec says.
Is 1V P-P enough for your equipment? This amp is easy to modify
and I can greatly improve the specs by running it at +/- 15V rather
then the +/-5V it now uses.
So, my opinion: Video distribution amps can work but you'll be right
on the edge of the spec'd limits all around.
