The Delta 21 is a dedicated 433MHz ISM band antenna which combines good performance with a small size, enabling its use with many of today’s remote control systems and 433MHz alarm systems. Terminated with an SMA male connector, it is ideally suited to applications requiring a simple, cable free set up, such as alarm panel equipment and garage or gate remote controls and radio systems including TETRA. The knuckle design allows the antenna to be positioned to take best advantage of the incoming signal. Allowing straight, 45° and 90° positions along with 360° rotation. The omni directional, radiating element is capped with a black high-grade rubber mould. Dedicated ISM Antenna
