Long Range Wireless RF Transmitter Controls 15 Receivers (One-to-Many System)

I need a system with 1 Transmitter and 15 Receivers.

The 15 Receivers will be “remote receivers” and will be located in 15 separate locations.

This 1 Transmitter will control all 15 remote Receivers (buttons 1 through15 on the Transmitter).

Range = 300m-500m

Voltage = 12VDC

Ampere = 1.0 – 5.0 Amps

We’d like to recommend you “One-to-Many System”. It includes a 15-button transmitter(CV-15) and 15 long range receivers(S1UB-DC12-ANT2). They can work together and their working distance is 2000M with external extended antenna. The maximum working current is 10 ampere. Each receiver is 1 channel, which can connect to one device. Control Lights, Motors, Fans, electrically operated Doors / Locks / Windows / Blinds / Cars or Other Appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. There are 3 working modes for each receiver. They are toggle, momentary and latched.
