I have a CM 1111 in pieces, which is simply the VHF part of a CM 1160, which I am using now. The quantum series was discontinued because Channel Master greatly reduced thier offerings. The HD7697 is nearly the same performance anyway, per my testing on a 45 foot height.
MR Squirrel is spot on regarding Winegards. They are still stronger than CMs and perform like Channel Masters used to. I recently put up a HD7697 with CM7777 mast preamp at our hunting camp, 40 miles NE of Scranton. It gets 5 the five transmitters there and two from Binghampton NY. There is only VHF-Hi and UHF there.
If you want ONE antenna for ch 2-51 HD and FM, I highly recommend the Winegard HD8200. Unless your RG-6 wire is less than 30 feet long, use the CM-7777 preamp and switch OFF the FM trap. Mine trap needs to be on due to two 25 kW FM stations which affect ATSC tuners which do not have very good filtering or image rejection.
first putting it on my tower...
