The 4221HD is optimized for distant "near-fringe" reception of HDTV. Its space-efficient design is suitable for roof and attic installations.

The 4221HD is classified as a Medium-sized 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 explaining how to choose and install an antenna for HDTV.

Features

Overview: The Channel Master 4221HD antenna is designed for UHF frequencies only (channels 14-69), both digital and analog. It can be mounted on a roof, on a wall, to a chimney, or in an attic.

Mounting Brackets: The mounting brackets and the U-bolt are used to mount the antenna to a mast. The outer diameter of the mast should be approximately 1-1/4 inches.

Turning Radius: If using a rotor on the antenna mast, make sure a 12-1/4" turning radius around the antenna is clear of obstruction.

Grounding: The antenna and mast should be properly grounded. Grounding provides lightning protection for the antenna and your TV set.

Note: No grounding hardware is provided with the antenna.

Connections: The balun is built-in (attached at the factory) and has a female F-type connector. The included waterproof rubber weather boot should be installed over the cable connection to guard against corrosion. A twist-on threaded F-connector is also included.

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

Operating Range: The rated range of the 4221HD is 45 miles, but the distance is approximate, actual performance depends on too many variables to predict accurately.

Gain: The average gain across the UHF frequency range is 10.2 dB.

Antenna

Written By el, Remo VA on Saturday, February 11, 2012

I used it with my camper on a recent trip to Fla. The camper's Delta amplified antenna only recieved one channel in the state park campground. I mounted the 4221HD antenna on a 12' pool cleaning pole and attached it to the side of the camper and it recieved over 25 channels. I saved the box and fold up the antenna for transport, it is a little big but I just throw the box on the bed during transport. Set up only takes about 5 minutes. The reason for the four star rating, when I first opened the box, the pop rivet holding one end element was not securing the element to the frame. I just drilled out and replaced the pop 3/16 pop rivet, no problem for me but for others you would have to return and replace the antenna.

Pros:

Great reception. Could not have watched the Super Bowl without it while camping. Ordered one day and on my door step the next day before the trip with free shipping, that was great service. Free shipping with the the other online A site usually takes about two weeks for me to recieve an item.

Cons:

Channel Master needs to inspect their antennas closer for defects prior to packing and shipping.
