Reception of Denver and Cheyenne signals with a single antenna will require a rotator. Because you plan to feed multiple TVs, I'm curious if there will be agreement as to which way the antenna should be aimed.

You could opt to install a single antenna with no rotator. I presume the Denver signals would offer the best selection of programing if you go with this option. The HD7697P and the slightly larger HD7698P are appropriate if you are going after the Denver signals.

If you mount in an attic, you'll be limiting your ability to receive the weaker signals. If you get a load of snow on the roof, expect reception to be worse. If I were in this same situation, I'd opt for mounting outside.

Regardless of which option you choose, you'll need to add a preamp such as the Antennas Direct CPA-19. If you intend to feed 3 sets, then use a 3-way splitter. Most 3-way splitters have two ports with lower output than the third port, use the low loss port to feed the longest coax run.

In addition to using a rotator, there are other options:
