Installation & Setup

antenna installation and setup

The installation process is relatively simple since the Channel Master Antennas CM-4228HD is pre-assembled.

You can start installing this antenna by following the instructions in the user’s handbook, but here, in this Channel Master Antenna review, you will see a quick rundown of the steps.

Step #1: Fold The Two Sections

Begin by folding out the antenna’s two front parts. To avoid overstretching the phasing strap, fold the right and left parts simultaneously.

Make sure to align the front pieces to the reflector array and level. Don’t forget to tighten the wing nuts.

Step #2: Mount the U-Bolts

Screw the U-bolts to the antenna that comes with it.

Step #3: Mount the Antenna

Install the antenna on the mast. The mast, however, is not included in the package.

Step #4: Link The Antenna

Link the antenna’s port using a coaxial cable (not included). To safeguard the connector, it’s best to clamp the cable to the mast with a cable tie. If you’re utilizing a pole, it’s best to use guy wires if it’s longer than 12 feet. If installing it outside, you should also line the antenna using a coaxial grounding block or a lightning arrester.

Proper Positioning Of The Antenna

The Channel Master CM-4228HD can receive broadcasts from Television networks 180 degrees apart from you.

You should adequately position the antenna’s front towards the TV broadcast towers for optimal coverage. Take note that the side of the transmitter with X-shaped parts is the front.

To position the antenna, first determine the location of the nearest television broadcast tower(s) in the vicinity. To achieve optimal transmission and stability, use a level tool. This is also to verify the vertical section of the J-mount is appropriately parallel to the ground.

Face the front of the antenna between the towers if you want to pick up signals from two distinct towers. You can position them up to 180 degrees apart.

Consider the following factors for the optimum signal reception:

  • Position the antenna as high as possible. As much as possible, ensure a clear route between the antenna and the TV broadcasters. Neighboring buildings, forests, and other tall structures can influence the effectiveness of your antenna. (1)
  • If you’re putting the antenna indoors, place it near a window on the side of the house towards the TV transmitter, presuming you have adequate space.
  • Maintain the antenna as far away from potential interference sources as feasible, such as air conditioners, hairdryers, household appliances, etc.
  • Retain the antenna away from any items that could create electrical disturbance in general. (3)

Frequencies, Transmission Capacity, and Signal Reception


As previously stated, the Channel Master AntennasCM-4228HD is a multi-directional antenna that can pick up signals from a 180-degree receiving angle; however, you must still face the HDTV antenna in the direction where the TV transmission tower.

Of course, our Channel Master Antenna review won’t be complete without the pros and cons section.

  • It supports uncompressed 1080i and 1080p HDTV transmissions and provides improved video and audio quality.

Video Walkthrough


Is it feasible for me to do the antenna installation myself?

Unless you are afraid of heights, you can assemble this antenna. In most circumstances, if you want to install this antenna outside, you’ll need to climb up and down onto your roof.

The installation process is pretty straightforward, and you should have no trouble doing so alone.

Is there a preamplifier included with the antenna?

Since this antenna does not come with a preamplifier, you may need to purchase one separately if you have the following issues:

– The length of your coaxial wire exceeds 50 feet.
– To split the signal into many TVs, you’ll need to use a splitter.

Using a preamplifier is also recommended if:

– The closest TV broadcast tower is more than 20 miles away.
– You are installing the antenna on the rooftop. Sometimes, high walls disrupt the signals.

Is it necessary to connect the antenna to a converter box?

You’ll need to purchase a digital converter box if your TV can’t pick up digital signals. Mainly, if not all, TVs produced after 2007 can acquire digital signals; therefore, if you bought your TV before 2007, you’ll most likely need a converter box.

Is it necessary to use a signal amplifier or router in tandem with the antenna?

The appropriate response will vary depending on where you live. You’ll need an amplifier if you’re too far from the TV broadcast tower (more than 80 miles for this antenna) or if there are several obstacles in your area.

However, remember that the amplifier enhances noise, so only use one if necessary.

Wrapping Up

The Channel Master CM-4228HD is an excellent outdoor antenna that may also be used on the roof or indoors.

It has a fascinating multi-directional structure that can pick up signals from two antennas separated by up to 180 degrees, even though you still have to point the HDTV antenna to the area of the TV transmission tower.

According to our tests, it has a network transmission range of up to 80 miles and is fairly reliable. It comes pre-assembled and is rather simple to set up; nevertheless, it does not include a mast, which you should purchase separately.

The antenna can’t obtain low VHF signals (it can receive high VHF), which is a minor drawback because it’s primarily built as a UHF antenna. It is also not the most affordable option, though it provides excellent value for money.

Overall, if you’re looking for a multi-directional outdoor antenna, the Channel Master CM-4228HD is an excellent choice.
