SHERLO 4-CH TX C-HOP 1500m

This Sherlo 4-channel transmitter is the extreme-range option of the family, reaching roughly 1500m to a matching long-range receiver. Four independently learnable code-hopping channels control gates, pumps, sirens and equipment across farms, panhandles and industrial yards where ordinary remotes cannot reach. It transmits on the range's 403/433MHz platform with the same rolling-code security as the keyring models. The practical answer when the receiver is three properties away from the button.
