I get 5 digital channels.

Three of them are pretty solid and the other 2 pixelate every few seconds. The solid stations are WNAC-HD from Providence RI, WLWC-DT from Providence, and WCDC-HD from Adams MA. The two marginal channels are WBZ-DT from Boston and WJAR-DT from providence.
I'm using an AntennasDirect 10G212 mast mounted amplifier. Would the difference between the CM Titan 7777 and the 10G212 be enough to potentially reduce the dropouts to where the two intermittent channels might become watchable?
My zip is 01440, the antenna is mounted about 25 feet high, with a rotator and 50' of RG 62 running to the television.
