Thanks for adding your experience with the TiVo, Mike.
While I was reading his post I did an FMFOOL report (see attachment) for his estimated location, in Redford Charter Twp, near Livonia MI, because they don't link like TVFOOL reports. He can do his own to see how they compare.
Your hunch was accurate because he has a very strong FM signal that might interfere with TV reception, and might need an FM filter.

a HLSJ (use high and common ports) also makes a good filter that attenuates everything below Channel 7 including the FM band with low loss for the TV signals:

Hello,
DStank:
You also have some very strong TV signals which might cause overload, but it might be multipath reflections because of the indoor location causing poor signal quality. Monitor the SNR and uncorrected errors on the TiVo to find the best antenna location.
If your TV has a digital tuner, you can compare the reception of the TiVo with the reception of the TV.

I have a spare cable amplifier from a previous Comcast installation that I haven't tried using yet.

Unless your indoor losses are more than average, you shouldn't need (or use) that amp because of your very strong signals. What model is the amp?
WKBD is your strongest signal with a Noise Margin of 69.7 dB even before adding the antenna gain.

I would like to place the antenna in the attic but I'm unsure how a long cable run might affect the signal.
|
Attic losses are difficult to predict. A metal roof, aluminum foil thermal barrier, aluminum siding, and stucco can block signals, as can trees and other buildings.

The loss for RG6 is about 6 dB per 100 ft at UHF; you have plenty of dB to spare.

maybe about 60 feet of RG6 and a few barrel connectors.

Sometimes F81 barrel connectors can cause a problem with a poor connection. I check mine by inserting a short length of 18 gauge bare solid copper wire (same size as the center conductor of RG6 coax) to see if the F81 grabs it firmly.
Try your HD Frequency Cable Cutter antenna in the attic with a temporary setup to see how it does before drilling any holes. Then add some more cable to simulate a basement run.

Generally that seems to be okay but every couple of minutes, some channels more than others, I have pixelation.
|
What channels are giving you a problem? Which channels are OK?
You might need to settle for one direction, like 50 degrees magnetic, for a good selection of desirable channels, instead of expecting to get all channels from all directions, which is unrealistic.
If your HD Frequency Cable Cutter antenna doesn't do what you want in the attic, consider using an Antennas Direct C2V up there. It has a reflector that makes the antenna directional to reject troublesome signal reflections, but has a 70 degree beamwidth to receive the grouping of signals coming from the NE.
