The only solution that I can think of that has a chance of improving your reception of WVUT would be a separate UHF antenna like the Antennas Direct 91XG or Solid Signal HDB91X at a greater height with an Antennas Direct Juice preamp. Both of those antennas have a tilt feature that would allow the front end of the antenna to be tilted up to catch the signal coming down from the crest of the hill; it often helps.
