To have a better chance for WGRZ you will need a separate high gain antenna outside, aimed at 177 degrees magnetic, and a preamp. WGRZ is 88.5 miles away, so the curvature of the earth is a problem.
A suitable antenna would be an Antennas Direct DB8e, 91XG, or the Solid Signal HDB91X clone if you are watching expenses. If you pick the HDB91X, be careful not to over tighten the coax connector on the balun.
A suitable preamp would be the CM7778 or Antennas Direct Juice.
