¶ General Description
The Tango 25 is a miniature dual-band Wi-Fi antenna designed for reliable 2.4 GHz and 5 GHz connectivity. Delivering gain between 4—6 dBi and efficiency of 70%, it combines strong RF capability with a compact 22 mm diameter design, making it well suited to Wi-Fi routers, gateways, wireless access points and other space-constrained networking equipment.
Its dual-band capability makes the Tango 25 particularly suitable for industrial IoT gateways, smart building systems, remote monitoring equipment and wireless control applications where dependable local network connectivity is required. Its compact design also makes it a practical choice for integration into equipment where a larger external antenna would be unsuitable.
The antenna features a durable ABS housing, IP65 rating and secure through-hole screw mounting, making it suitable for indoor and protected outdoor installations. It is supplied as standard with a 100 mm cable and reverse-polarity SMA male connector, with alternative cable lengths and connector options available for volume orders.
