KING SureLock <br>(SL1000)

KING SureLock

The KING SureLock is a foolproof way to locate over-the-air 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 KING SureLock ensures you are pointing in the right direction for a successful channel scan.
