Terminal Armament, one of our resellers of RTL-SDR V3 dongles in the USA has created a companion product called the SDR Special Tool Kit (SDR-STK) which is a tactical ruggedized enclosure for two RTL-SDR V3 dongles. The SDR-STK consists of a two port USB hub enclosed in a water-resistant housing, and a rugged screw on USB-A cable. Two SMA connectors protrude out the top. The design is open source with designs and software due to be released on their GitHub in time.

The SDR-STK is estimated to ship within 5-7 weeks, and is available for pre-order via the Terminal Armament website.

The RTL-SDR dongle has long been the standard for an entry-level software defined radio. And while we do love it, the USB dongle form-factor is simply not suited for rigorous outdoor use. This is why we've developed the SDR-STK.

The SDR-STK is a ruggedized two-port USB hub specifically designed to fit two standard RTL-SDR dongles, and provide a durable, water-resistant housing. Having two dongles also grants capabilities not available with just one; these go beyond simply increasing the bandwidth. With one receiver acting as a tuner, you can have the second one preforming other tasks such as wide-band scanning, listening to a trunked radio control channel, or simply receiving other information such as ADS-B packets.

The SDR-STK isn't just a one-off hardware product. In the coming weeks while the pre-order is active, we will be releasing various software utilities for the SDR-STK on our GitHub, as well as the PCB schematic files. We're firm believers in Open-Source hardware software, and we hope to use this launch to kickstart several other communication related products and projects such as better Android SDR applications, and other SIGINT tools.

The SDR-STK includes itself, and a custom 1.5 foot USB Type A Male cable. Antennas and RTL-SDR's are not included unless specified or ordered in conjunction with the SDR-STK.
