I have been offered one of these:


Specifically the model :

ADA 6 300MX HV HDTV RGBHV 1 x 6 Analog Video Distribution Amplifier

I *THINK* it should meet my needs except the HV bit worries me. It
seems this means it has not got unity gain, but a gain of 0.7 or 1
volt, switch selectable. Could anyone comment if it's suitable to use
my Trimble Thunderbolt with several pieces of test gear at the same
time? Thanks. Here in the UK the ADA-3-80 seems a rare find.

       Best Regards,
                   Chris Wilson.
