622 tv2 output signal is it weaker than 4700 rf out

[odbrv]

Just got my price increase. I need to reduce some cost. I currently have a 4700 feeding 3 sd tvs in other rooms up to 75 feet away. There is an amplifier on the cable run. I am using a 622 in single mode. So I thought I could get rid of the 4700 and save $7.
I disconnected the 4700 rf out and connected it to my 622 tv2 out. I reset the 3 sd tvs to the uhf channel for tv2 cable out. No matter what I do with setting the amplifier gain control , I get a snowy picture at all 3 sd tvs. When I reconnect to the 4700 and go back to channel 3 on all the sd tvs, the picture becomes sharp again. What I did not try is going over the air. I would have to get 3 uhf antennas for the 3 sd tvs. Anybody have any suggestions.

First thing I would try is to bypass the amp and go direct to a/the tv's. Also a lower uhf channel(s) for tv2 out may work better.

also go into the modulator menu and make sure it is set to home distribution, not direct connect.

Had the same thing when I changed to dish from directv .
tried to go as low as i could but still ended up adding a second amp .
