The BLONDER TONGUE BIDA BROADBAND DISTRIBUTION AMPLIFIER 750-30
manual says it's designed for cable-drop input, sounds like the right input level to me, although it doesn't say what signal level exactly.

The BIDA 550-50 would privide a stronger output, IF it doesn't overload. I would be tempted to try this one first and hope that if it overloads it can be adjusted out with the attenuator, or even by adding an external attenuator if necessary.
