Any of these antennas will work indoors, but they are kind of big if you don't have a lot of room.
The other thing you need to consider is that some homes have building materials that can block radio signals pretty well. Plaster walls with metal lath, foil backed insulation, foil vapor barrier, metal siding, etc. Even some windows can have metallic film tinting. If your home has any of these, using the antenna indoors might be an issue.
One way you can test this is to set up your radio in the home and see what the signal level is. Then take it outside and see if it improves considerably. If there is a big difference, you may not have sufficient results with one of these antennas inside your home.
A TV antenna mount would work well.
Since these are directional antennas, they work well in one direction. Not so well/awful in others. This may be a problem unless the towers from both counties are in (or nearly in) a straight line in one direction from your house. If they are not, you may have issues, and you may need an omni-directional antennas.
Think of these antennas as a telescope. Your radio will "see" best in one direction, and you'll miss everything else.
