Product Research


Overview: The Channel Master Digital Advantage 100 (Model CM-2020) is a directional (yagi), line-of-sight outdoor TV antenna that receives high definition and digital signals up to 100 miles away. With a total of 41 elements, it is engineered to receive high quality UHF/VHF high band frequencies. It is classified as a large directional antenna by the Consumer Electronics Association (CEA).

Reception Range: This antenna receives only VHF channels 7-13 (VHF high band) and UHF channels 14-51. It does not receive VHF channels 2-6 (VHF low band). To receive channels 2-6, an oversized antenna is required. The reception range and average gain for this antenna are as follows:

  • VHF Channels (7-13):
    • Reception Range: 100 miles
    • Average Gain: 7.5dB
  • UHF Channels (14-51):
    • Reception Range: 100 miles
    • Average Gain: 9.4dB
Note: All distances are approximate, actual performance depends on too many variables to predict accurately.

Mounting: It can be mounted on a roof, wall, chimney, in an attic, or on a tripod. The manufacturer's suggested height limit is 10 feet above the rooftop.

Turning Radius: Model CM-2020 has a 6' turning radius. If using an antenna rotor, you must make sure there are no obstructions around the antenna mast that would interfere with the antenna's rotation.

Connections: The included 75-ohm matching transformer is connected to the antenna tap-off points using the included wing nuts. The other end of the transformer has a female F-type connector. The included waterproof rubber weather boot should be installed over the cable connection to guard against corrosion.

Note: Coax cable is not provided; RG-6 is recommended.

Grounding: The antenna and mast should be properly grounded. Grounding provides lightning protection for the antenna and your TV set. A #8 or larger aluminum or copper wire connected between the antenna and grounding rod should be used.

Everyone is right here! Long range antennas work in any area where all your stations come from one direction. If you are not sure about the direction the stations are coming from, you can check here: We have advisors that you can reach by calling 1-800-324-9695 who will look at this with your to help find the best antenna for you and the stations you want to receive My Bio:

I bought this antenna after our previous antenna got wrecked when a large branch came down during a storm and broke the antenna in half. The Channel Master CM-2020 is pretty easy to assemble and it pulls in a lot of channels. You just need to mount it on a mast and find out what direction to point it in. It helps to have someone looking at your TV and reporting back to you as you adjust the direction the antenna is pointing, so that you can receive the maximum number of channels. (Luckily I don't need a rotor to maximize my number of channels received.)

I'am not from South Florida but I bought the mentioned products and work fine. It's me get tv coverage after the Maria Hurricane in PR. The antenna and my own power source kept me inform!
[ Carlos  Apr 24, 2019 ]
This works very well no cable bill every monthEnter
[ ELIOUTT  Apr 24, 2019 ]
I purchased mine for PR and it works very well even having interferences from the mountains. By experience, get the biggest one you can get. It will have the best receptions compared to smaller units.
[ Ramon  Apr 24, 2019 ]
Can two of these antennas be coupled together to pick up transponders in different directions?

Yes, .... that's what I did to pick up two more channels there is another 2 in Tulsa that I have to rotate the antenna to receiveEnter
[ ELIOUTT  Mar 25, 2019 ]
Electrically I think it would create conflicts and interferences, but it is a good question for an electrical engineer to confirm.
[ Ramon  Mar 25, 2019 ]
hello, will this pick up local news channels in maine?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ Kenny  May 27, 2017 ]  Staff
If installing this myself - which end of the antenna should face the incoming signal? The wide end or the pointed end?
[ Gwen  Jul 22, 2015 ]

The pointed end toward the signal source. -dh
[ david  Sep 15, 2015 ]
The pointed end
[ CHARLES J  Jul 23, 2015 ]
The pointed end of the antenna needs to be pointed in the direction of the transmission tower.
