Siretta DELTA 12 Series Antenna, 130mm Length, 3dBi Gain - DELTA12B/x/SMAM/S/S/17

This Siretta DELTA12B/x/SMAM/S/S/17 antenna is a Compact terminal-mount whip designed for ISM band radio systems operating around 863–870 MHz. It uses a 1/4-wave radiating element in a flexible rubber whip format and connects via an SMA male interface. The design suits space-constrained installations and mobile sensor nodes requiring an omni‑directional radiation pattern.

Features and Benefits:

• 3dBi gain improves link margin for low‑power radios
• Omni‑directional directivity ensures uniform coverage in all directions
• 1/4-wave radiating element reduces tuning complexity for ISM bands
• SMA male connector enables secure RF connection to terminals
• Rubber whip construction provides mechanical flexibility for installations

Applications

• Suitable for LoRa sensor terminals in urban deployments
• Ideal for industrial ISM wireless telemetry equipment
• Used with remote monitoring devices requiring Compact aerials
• Can be used for short‑range asset‑tracking radio nodes

What temperature range can it operate within?

It is rated to function between -30 °C and +75 °C.

What impedance and VSWR characteristics does it present?

The antenna has 50 ohm impedance and a VSWR below 3.0:1 across its band.

Which frequency span does it cover for ISM applications?

It operates across 863–870 MHz supporting the 868/869 MHz ISM allocations.

What mechanical mounting method is used for Terminal installations?

A direct terminal‑mount arrangement is provided for secure attachment.
