CIII-DT 6 and CKCO-DT 13 are the 2 weakest receivable stations. I do not think a antenna amplifier will be needed with the 2 Tv's and FM tuner hook up. However if the 2 stations are on the edge of being received reliably. A AntennasDirect CPA-19 preamp ,

I recommend install the UVSJ as close to the antennas as possible , but still get out of the direct weather , rain and snow , put it up under a eave or in the attic. Also I recommend a Winegard CA8800 TV-FM separator , it separates out the FM to the FM tuner and the Tv channels to the Tv.
