Siretta DELTA43/x/SMAM/S/S/17 Whip Omni-Directional Antenna with SMA Connector, ISM Band

This Siretta DELTA43/x/SMAM/S/S/17 antenna is a Compact direct-mount whip designed for ISM band radio links operating across the 400–480 MHz range. It attaches directly via an SMA male connector and provides omnidirectional coverage with a swivel knuckle for adjustable orientation. The device is specified for typical deployments where a small form factor and configurable alignment aid signal reception in remote reading and Terminal applications.

• 2.5 dBi Peak gain improves link margin and reception range
• 50 ohm impedance minimises mismatch loss for RF systems
• VSWR greater than or equal to 1.5:1 reduces reflected power and enhances efficiency
• Vertical polarisation aligns with common handheld receivers
• 50 W maximum input power supports moderate transmitter outputs

• Suitable for smart water meter remote-reading systems
• Ideal for Terminal devices requiring ISM connectivity
• Used with industrial telemetry and monitoring equipment
• Can be used for handheld receiver-linked data collection
• Suitable for OEM devices needing direct-attach antennas

It operates reliably between -20°C and +65°C.

It provides omnidirectional radiation for uniform azimuth coverage.

It weighs 40 g and is supplied as a whip with a swivel knuckle.

It uses an SMA male connector and a direct-connect mounting method.
