With the CM4228 do I need to also get the CM 7777 amp?
I plan on getting these today .
You might need it and you might not, only trial will say for sure. Many use it (me included, but I am far away), some had it overdrive some of their channels. I would buy it personally, but Dowdoes not take returns.

I'm getting the CM4221(3021) which is about half a CM4228 and half the price. I'll try installing in my attick next weekend with no amp. I'll post the details afterwards.
Currently I have a pair of rabbit ears in the attic and I pick up NBC, ABC, FOX, PAX with no breakups pending good weather - UPN, TBS, TBN with minimal breakups but no CBS. I'm right off Acworth Due West near Stilesboro Rd about 25 miles from the towers.
And twice the install if you have to replace it with the 4 bay.
