Channel Master CM 5020 Masterpiece
Directional long-range outdoor rooftop TV antenna
Our take on the Channel Master CM 5020 Masterpiece by Crutchfield's Steve Kindig
With a moniker like "Masterpiece," Channel Master's CM 5020 antenna had better be pretty good — and it is. It's recommended for "deep-fringe" applications — its large size and numerous reception elements help it pull in signals from distant transmitters. It pulls in over-the-air TV signals in the UHF and VHF bands — probably more channels than you knew were available.
To get the most channels possible, try adding Channel Master's 7777 preamplifier. Also, if you'd like to pull in signals from two or more different locations, you may want to consider a rotor to aim your antenna in the right direction.
The CM 5020 is classified as a Large Directional antenna. For tips on selecting an antenna, and links to websites that help you locate HDTV signals in your area, check out our article on choosing the best HDTV antenna.

Why did you buy this?
It is replacing an older antenna that has seen better days. After researching a number of options this seemed the most suitable as I am definitely in a "Deep Fringe" location and the weather (wind mostly) is quite a challenge. With it's low profile and hopefully strong build it seems to be more up to the task than any others I've researched. [ David Feb 01, 2018 ]
Channel Master has a good reputation and this antenna should work on our remote farm to pickup broadcast TV. [ Rhonda Jul 20, 2017 ]
Mainly the 16db UHF gain. Like my very old very large antenna, I am wiring it to be split 5 ways without an amplifier. Being 35 miles from the station towers, I am expecting this antenna to pull in very strong signals that can be split to 4 TV's and FM receiver, like my 25 year old radio shack antenna could do before it broke. My small attic antenna can't hold the FOX TV station even with no splitters. This antenna will replace old antenna and be 5 feet above the peak of the roof. [ William May 29, 2017 ]
needed the long distance capability to get Baltimore, and maybe a few DC stations [ Dennis Dec 15, 2016 ]
Highest rated distances according to descriptions. We'll see if it lives up to the description. If not, Crutchfield has the best customer service on the planet so I always buy from them with complete confidence. [ Greg Dec 08, 2016 ]
100 mile radius [ Joshua May 16, 2016 ]
on paper this unit has the longest range with highest gain available. [ clionton May 12, 2016 ]
Recommended by Channel Master for our long-range application. [ TOM Feb 16, 2016 ]

If you want that type of protection it will require using an inline surge protection module that must be purchased separately for that. Then you will ground the module to prevent any down stream surges. Use in an attic should help with lightning but nothing is as good as a good protection unit near the TV. [ Jeffrey Jul 26, 2017 ]
Yes. I recommend a search of your address on the site, TVFool. This is a great resource to help you decide what type of antenna is best for your home. By the way, I couldn't be happier with my Channel Master CM5020. It pulled in even more channels then TVFool expected. [ KEITH Jul 06, 2017 ]
Yes. [ jamie Jun 14, 2016 ]
I am not sure if, or how much RF, the foam will block. Your main concern with an attic installation, provided no signal loss, will be having enough room to aim the antenna. Mine is outside on a pole with a rotor. [ Michael Jun 13, 2016 ]
Hi Chad, you will have to buy a pole separate to mount it. All you will receive will be the antenna. Depending on the distance from the towers, you will want to consider a signal booster as well. Good luck!! [ Antony Dec 24, 2015 ]
Even though an antenna mast is shown with the CM 5020, none is supplied. I used the Channel Master 1805 mast to mount the Channel Master 5020 in my attic. I used "U" bolts from a local hardware store to mount the mast to the ceiling joints. It works well. [ Maurice Dec 15, 2015 ]
BTW, I live about 70 miles from most stations, but was even able to get one from close to 90. [ Jim Dec 14, 2015 ]
Chad, the antenna comes ready to bolt onto something. I had an old aluminum pole that I saved from a patio furniture umbrella. The antenna will accommodate a small range of sizes, so my "repurposed" alum pole worked great. Of course then you will have to attach that pole to something to hold the antenna. I also purchased an amplifier from Crutchfield to use the antenna. It did not work without it, but I am completely satisfied with my purchases.NOW it works great. ( I think this is starting to sound like a paid ad) I want commission from them! Jim [ Jim Dec 14, 2015 ]
We did not get a pole. The U bolts, nuts & washers are included so you could probably attach it directly to a vertical 2"x 4" brace that's in your attic. You might have to drill some holes in the 2"x 4" to accommodate the U bolts or buy a 2"x 2" x 8' and cut to the length you need and secure it to that. [ MICHAEL Dec 14, 2015 ]
