but I've received good reception before only to have it break up and pixelate and go back to good reception

it improved reception somewhat

If you live in the city or where there are cell towersall about this works to clean up you TV reception

Much better reception

NO random outages, just PURE reception on ALL channels

Along with the Channel Master signal amplifier,it improves reception 99%.

We have had a really good antenna system with a CM-7777 amplifier ever since the digital transition, but slowly over time the reception got worse and worse and finally just stopped working

I love this filter because it will help fix poor receptions on your TV set.

I live within a 1/2 mile of a cell tower and installing this helped improve my reception for my OTA channels noticeably.

I would say it is only useful in urban settings with lots of cell traffic, or the occasional countryside setting close to a cell tower; otherwise, it'll hurt your reception more than help it
