Product Description
Siretta ALPHA40/2.5M/SMAM/S/S/29 T-Bar omni-directional multi-band antenna is engineered for advanced wireless communication, suitable for GSM, GPRS, 2G, 3G, and 4G mobile networks, as well as Bluetooth and WiFi modules. With adhesive mounting pads designed to maintain an air gap, the antenna delivers stable signal transmission and is well-adapted for integration into communication equipment, terminals, gateways and IoT devices.
The antenna’s balanced dipole construction and T-Bar form factor allow for easy installation and ensure uniform gain across multiple frequency bands. Maximum gain reaches 2 dBi at 2600 MHz (4G), while performance remains excellent at lower bands, with 1 dBi at 3G frequencies (2100 MHz) and 0.5 dBi at 700 - 824 MHz.
Its 2.5 meter PRO100 low loss cable ensures flexible mounting and signal integrity, and the direct SMA male connector simplifies integration onto device bodies or enclosures. The wide 699 MHz to 6 GHz frequency compatibility makes this antenna ideal for industrial wireless applications, commercial gateways, telemetry, remote monitoring, and automation systems.
Internal mounting further strengthens reliability in challenging environments. The T-Bar form is compact (155 x 30 x 4.5 mm), making it suitable for space-constrained electronics requiring robust antenna solutions.
Reliable omni-directional coverage for mobility and device flexibility. Multi-band support for simultaneous connection to voice, data, and IoT networks. Balanced dipole architecture ensures consistent gain and low interference.
Designed to comply with EU standards for electronic components. High-quality manufacturing with proven Siretta brand reliability.
