80 MI Range Antenna

Well Designed Antenna. CM4228HD

August 22, 2024,
Antenna: CM4228HD
Well designed antenna. Eight, phased, broadband dipoles to give a theoretical gain of 12 dB. I used a 1.5 EMT pipe with an outside diameter of 1.75 inches all mounted on tall 4x4 mast, 25 feet above ground.

Amplifier: CM7777HD
A Channel Master Amplifier CM7777HD was mounted and connected on the mast a few inched from the antenna balun and set to 13 dB gain.

The reception from TV stations approximately 55 ~ 60 miles distance is exceptionally and outstanding. All stations in my local are approximately in the same direction, so no rotator required. Receiving both High VHF and UHF.
I highly recommend this combination of antenna and amplifier.

Great product

Well packaged box. Instructions were clear and simple. Installation was easy. Boot for end of coax cable must be put on before the connector is in place. This new antenna replaced a deep-fringe yagi antenna. This antenna's broader reception pattern made new stations come in that were previously not in the narrow pattern of the old antenna. Very pleased thus far. Only been in use a few hours but happy.

Great antenna!

After installing this antenna We even noticed that the digital quality of picture was more defined. Getting 35 channels here in the Mountains of Virginia and are receiving stations now well over 100 miles away. Most of our channels are 70 or so miles away so its really a great antenna! I installed it appx. 35 ft high.

Great antenna

Great quality and last a long time. About 80 miles from stations, installed and receive 34 channels. No booster and 20ft off the ground.

Easily picking up stations 70-90 miles from home, antenna is 20ft off ground with booster

There is no school like the old school! I hate paying monthly bills, and this is a great way to get rid of a cable bill. Was using mud flap style antenna and generally getting in about 42 channels (about 30-50 miles from location). Putting this antenna outside at about 20ft high with booster I'm now getting 83 channels (70-90 miles from location). And the channels are very stable at that distance. I rotated the antenna several times and did channel scans, once I found the best overall spot I bolted it in place. Very happy with this purchase.
