Thank you all for your feedback. Now I have more questions.
The main TV for the Hopper would be the living room. I'm currently thinking a Joey for the master bedroom. The fire stick is a great suggestion and with never using one, is it plugged into a HDMI or USB port of a television? That would be great for the downstairs guest bedroom when Mom comes for a visit.
I am comfortable with the remaining TVs all watching the same channel as it is rare for someone to use the 2 upstairs bedrooms, the TV in the loft is mainly for the grandkids video games, the kitchen TV would be playing whatever is in the living room since both rooms are open to each, the basement tv rarely is watched, and when I'm in my laundry/sewing room I normally would be watching whatever was on in the living room. I do have a Dish Sling so if I did want something for one person to watch, they could do so with an iPad or tablet but I guess that is not an option if someone is using the Fire Stick.....correct?
Back to the RF modulator that I would need to make one Joey work for the remaining TVs in the house that wouldn't have their own Joeys or a Fire Stick. I see numerous RF modulators out there from less than $10 to several hundred dollars. How do I know which to purchase?
Thanks.
