No, don't stack two HD8200U antennas, just use one.

I think stacking two would create more problems than it is worth, but the final decision is up to you. It is your money and your antenna system.

Channel Master doesn't make, as far as I now, a separate FM filter, but there is an FM filter in the 7777 and 7778. They do make a separate LTE filter for cell phone interference.

To see if you have interference from other services, you would need a spectrum analyzer, which is expensive.

Otherwise, it is trial-and-error to see what helps if you have an interference problem.

Cell phone transmitters use different frequencies according to what carrier is in your area. Some use frequencies just above TV CH51; others use higher frequencies that cause less interference to TV reception.

For some inexplicable reason, Southbridge is a terrible place for TV reception. I have done a couple of installations in the area, always with limited success. Boston is the most likely reception target. It is all UHF, and the transmitters are are on very tall towers and are very powerful, so an HD8200 is a waste if you are looking primarily for Boston.

If you want Providence, WPRI and WNAC are on channels 13 and 12, respectively. There are NO low band VHF stations anywhere in the area, so, again, there is NO value using an HD8200. You would be better off using a high-band VHF yagi and a high-gain UHF antenna like an AntennasDirect 91XG or a DB8e and a rotator. Use a preamplifier only if you are running very long lines and/or multiple TV sets.

You don't need to make this harder than it is: Boston is your best bet. I know how hard any kind of reception in Southbridge is: I can barely even get any FM radio reception when I am in Southbridge.

Not to be flippant, but if you want fo DX, get out of Southbridge:it's a terrible place to DX anything! You can't get a tower high enough to DX from that location!
