Our wiring is coax built into the house. I plan to use the splitter in the wall box for a cable to each of three TVs at 80 ft (seldom used and mostly for Wi-Fi streaming), 30 ft and 40 ft (used all the time).
Don't use the same coax for OTA signals and WiFi streaming.

I prefer not to use an amplifier so the question is should I try it once I get the antenna or is it clear that I need one?
Try it without the CM3414 distribution amp first, on one set, then add a 4-wqy splitter. That will tell you if you need the amp.

If you need the amp it can be remotely powered something like this, which was for another situation:







The coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.

You have some strong local FM signals that might be a problem. Add an FM filter. See attachment 4 for an approx. report. You can run your own report here with your exact address:

FM reports don't link like TVFOOL reports.
