Hi Without the taps, the Spectracom system really does not do much for you at all. There is no isolation / no buffering / no nice multiple output frequency stuff. Much cheaper and easier to just use a simple 10 MHz amp if that is all you want to do.
Since you have significant voltage on the line, just dropping a 50 ohm load on there is a bad idea ….
