UHF Extension for Pro-Model TV Antenna



The Channel Master Pro-Model UHF Extension is a modular antenna add-on designed to increase the UHF signal reception capability of the Channel Master Pro-Model TV Antenna (CM-1776). The Pro-Model UHF Extension is designed to work exclusively with the Channel Master Pro-Model TV Antenna. (UHF Extension will not work with any other antenna or as a stand alone UHF TV antenna).                   
- Patented (U.S. Patent No. 11,532,885)

The Channel Master Pro-Model UHF Extension is one of two optional add-on antenna sections that will enhance the signal reception capability of the patent-pending Pro-Model TV antenna. The Pro-Model UHF Extension is intended to improve the UHF signal reception and range by increasing UHF signal strength and signal quality putting it on the same UHF playing field as our longest range, large outdoor TV antenna models including the CM-3020, CM-5020 and the CM-4228HD.

The Pro-Model UHF Extension includes the necessary hardware to easily attach the extension to the Pro-Model antenna. Just like the Pro-Model itself, the extensions are well-constructed and maintain a sleek design that elegantly presents itself in commercial and high-end residential environments.

As with all Channel Master products, the quality of materials and product craftsmanship is our highest priority. The Pro-Model is assembled and packaged at Channel Master's Chandler, Arizona corporate headquarters. The antenna boom and elements are made from high-quality 6061 and 6063 aluminum and extruded, cut and drilled in the United States.

Love Channel Master

My favorite TV tower is 20 miles away and pointed away from me. I get great reception with Channel Master antennas

Tom Martin
Great Customer Support

Associate recommended the Pro-Model UHF/VHF TV Antenna with the UHF Extension and TV Antenna PreAmp 1. Installation was straight forward and very laid out. System works as advertised. The People at Channel Master are very helpful and interested in customer satisfaction.

Randy Simoneaux
Best antenna

I live 35 miles from the tv stations, I'm also in a low spot. This antenna works great so I ordered the extender to make it more efficient on bad days, it didn't disappoint. Can't go wrong with Channel Master.

Great quality and construction

The added antenna has boosted my reception to almost all channels. I'm in Jupiter and most of the channels are 25 to 45 miles away. There is one channel that still is a little pixelley at times but not as bad as before. Bounce. All in all, the reception is much better.

Problems with UHF signal now fixed.

I purchased the UHF extension to help with a UHF digitizing screen on all my UHF channels. My problem has completely gone away the picture is perfect with no digitizing screen .
