¶ General Description
The Tango 73 is a high-performance, ultra-wideband antenna designed for reliable connectivity across the 700–960 MHz and 1700–6000 MHz frequencies, supporting 5G NR, 4G LTE, 3G UMTS, 2G quad-band GSM, dual-band Wi-Fi, LTE Cat M, NB-IoT, LoRa and ISM bands including 868 MHz, 915 MHz, and 5.8 GHz.
Despite its miniature form factor of less than 50 mm diameter, the Tango 73 delivers omnidirectional coverage with 2—4 dBi gain, providing stable, high-bandwidth RF performance for industrial IoT, routers, gateways, telematics, and next-generation wireless applications.
Its compact IP68-rated puck design offers durable anti-theft and tamper-proof protection, while the through-hole mounting enables discreet, low-profile installation in demanding indoor and outdoor environments. The antenna is supplied with an SMA Male connector as standard, with alternative connector options available from Siretta.
¶ Key Features

- Supports 5G NR / 4G LTE / 3G UMTS / 2G Quad-band GSM
- Supports Dual-band Wifi 2.4 GHz and 5 GHz
- Covers LTE Cat M, NB-IoT, LoRa, IEEE 802.15.4 and ISM 868 MHz / 915 MHz / 5.8 GHz bands
- High bandwidth and 2—4 dBi gain
- Durable and compact puck design (anti-theft and anti-vandalism)
¶ Typical Applications
-
Public-facing IoT devices (kiosks, EV chargers, vending machines, smart parcel lockers)
-
Smart utility and industrial monitoring systems
-
Transportation, telematics, and fleet management
-
Industrial routers, gateways, and edge devices
