Amplifier For VHF TV

I have a rather complicated TV reception system. I have four antennas all successfully combined into one by using modules to convert the RF signal to VHF siganls. What I am lacking is a constant input for all signals into the combiner.

I would like to take signals from 54-216 MHz with 1-8 dBmV input and put out 18-25 dBmV with as little noise as possible. It would be great if I could clamp all signals to 25 dBmV.

The Televes Avant X would be an ideal solution for that situation. The Avant X is pretty much an MATV headend in-a-box. It is a filter > processor > amplifier allowing to individually filter RF multiplexes coming from up to four different antennas, automatically adjusts the levels individually for a balanced response, and even allows to frequency-shift when needed if two same RF frequencies are coming in from two different markets.

On top of that it doubles as a launch amplifier with a programmable output level between 30 and 55dBmV.
