Our take on the Channel Master CM-4050HD CLEARtenna

Think of Channel Master's CM-4050HD CLEARtenna as 21st-century "rabbit ears." The compact design can be clamped onto the top of a TV or placed on a tabletop. Watch your favorite network shows in crystal-clear high definition without paying a penny in monthly subscriptions. This is an amplified antenna, and it performs very well when your location is relatively near the local TV stations you want to watch. The CM-4050HD is a great choice for connecting to a TV or a computer with a TV tuner.

Cut the cable cord one month ago and thrilled with reception of local channels. Miss ESPN and other sports channels but saving over $1,000/yr in cable cost is worth it!

Good Deal for the money

Crutchfield Customer Review (What's this?)

Unobtrusive design. Gives a nice, clear signal on over-the-air broadcasts. Super easy to set up. Got all my local channels back and didn't have to have Comcast ravage my bank account to get them.

Pros: Inexpensive. Good reception.


Great LIttle Antenna

Crutchfield Customer Review (What's this?)

Great little antenna if you have a lot of local stations in close proximity, like we have in San Antonio. That being said, I still encounter a good deal of pixilation on certain digital stations and the abundance of Spanish stations is not the fault of the antenna, just a nuisance, LOL. Tried it out as the antenna for my AV receiver and the FM reception is awesome, so I will probably wind up going with a rooftop antenna at some point for the TV and just use this for FM reception. It was worth the money but I wish it had a little more range; seems to fall short of advertising, but that may also be due to location in the house and other environmental factors I'm not aware of. Overall, a good purchase.

TV antenna

teege from Rio Rancho, NM on 9/19/2013

Crutchfield Customer Review (What's this?)

This antenna is replacing a set of bunny ears in an attempt to receive a local channel better. It's easy to install and looks better than the bunny ears I had, but it doesn't work that much better. The channels I already was getting good reception on look a better, however the local CBS is just slightly better.

Pros: Price, looks.

Cons: Works just OK.

Worth the money

Crutchfield Customer Review (What's this?)

Antenna performs well. We are over 50 miles from metro area and the antenna pulls in all the available digital and analog stations. Well worth the money.

Pros: Looks good, hardly notice it on the TV.

Cons: mount for the tv could be better, but it does the job.

Decent Indoor Antenna

JeffM from Houston, TX on 7/14/2013

Crutchfield Customer Review (What's this?)

This antenna is nice and small, so it is residing nicely behind my TV. For reception, I am getting four of the main channels here in Houston, and the picture quality over the air is amazing. Still, considering I live inside the 610 loop here in Houston, it is disappointing that I am not bringing the local CBS, ABC, and PBS stations. I can see going to an outdoor omnidirectional in the future.

Pros: Small form factor, low price.

Cons: You get what you pay for in terms of the number of channels brought in.

Crutchfield Customer Review (What's this?)

For the price, this is a nice product. I get the same # of over the air stations as my non amplified antennae but with a lot less interference and pixilation - even during Changes in weather . I especially like the clamp that fixes the antenna to the TV. I make far Fewer adjustments with this antenna and it is a little bit nicer looking than the flat white non amplified antennae that I was using. With the amplified antenna, I was also hoping to get another station or two - but that did not happen. I am satisfied with the better quality if the stations I do receive.



Should have done this long ago!

LisaB from San Mateo, CA on 6/20/2013

Crutchfield Customer Review (What's this?)

I wasn't sure that an antenna would really work, but this one does! It was VERY simple to set up, and using one of the available channel locators on line, I found out the exact location to point it for the best signal (I lined up the antenna using my smart phone's compass app and it is perfect!). Because I have a nice 46" LED "Smart" TV, I wasn't watching my cable any more. Now, with this investment I can tell my cable company "bye-bye!" I have 65 stations (I think over half HD), including the 3 major networks in HD and public television. I don't need anything else and I am thrilled to be able to have one less bill to pay. Even if you have multiple televisions in your home, the investment to buy several would definitely be worth it.

Pros: It works! It is inexpensive. Simple to set up. This one is very small and easily attached to the side of my set using the included bracket.

Cons: Power cable could be a little longer. I would've preferred to "hide" the device (even though it is not unattractive), in the tv cabinet, but it doesn't pick up the signal as well.
