I'm not willing to promise you would see dramatic improvement if you replace the CA8100. But it would not be my first or second place recommendation to your next door neighbor trying to 'cut the cord'.

If I was starting from scratch, I'd definitely consider the HD7698P, it's an excellent single antenna choice. But I would very likely go with separate UHF and High-VHF antennas. For UHF, the Antennas Direct 91XG or the Winegard HD9095P. For H-VHF, an Antennacraft Y10713 or Winegard YA1713. I would use an Antennas Direct PA-18 preamp on each antenna, then combine the outputs of the preamps downstream of the power insertion blocks. I would resist the temptation to use a distribution amplifier with only 80' of coax to drive on the longest total run. I would opt for a passive 4-way splitter, depending on the gain of the PA-18.

WLQI FM 97.7 appears to be close in, I'd place an FM trap between the antennas and their preamps.

Out of curiosity, with the CA8100, do you receive WOCK real CH-4, reliably, intermittently or not at all?
