A pre-amp is a better choice. This puts the signal boost closer to the antenna so that the coax losses are kept at a minimum. Distribution amps usually go indoors and that usually means there's been more coax signal loss before reaching the first amplification stage.

Pre-amps can make things worse if you have strong signals nearby that might overload the amp (this causes distortion across all channels). However, in your case, I think you are safe since none of your signals appear to be too hot to handle. When signal levels in the "Pwr (dBm)" column get to about -30 dBm or higher, I start to worry, but you don't have any signals that strong in your report.



The CM 7777 is a good choice for your situation.
