The SureLock is a foolproof way to locate over-the-air (OTA) TV signals no matter where you are. If your antenna can get the signal, the SureLock can find it!

Since the transition of free over-the-air (OTA) TV programming from analog signals to digital signals in 2009, pointing your directional TV antenna – from an RV, travel trailer or even a second home – has become difficult and often time consuming. Unless your antenna is pointed directly at the TV tower, it is impossible to find channels when doing a channel scan. The SureLock ensures you are pointing in the right direction for a successful channel scan.

SureLock Design & Features

The SureLock is designed to ease your frustrations by simplifying the process of finding and locking onto an OTA TV signal from your directional antenna. Here’s how it works: The meter connects to any TV antenna output, or it can be installed in-line between your antenna and TV. When you rotate your antenna, the SureLock provides real-time LED feedback indicating signal strength, so you know the exact moment you lock onto a signal – no more guessing! It also has a variable sensitivity adjustment to work both near and far from the TV towers.
