Stream of Consciousness

Silvus Technologies will start accepting orders for the company’s new StreamCaster Lite 4200 in early April.

Silvus Technologies has given Armada more details of its new tactical radios and waveform enhancements.

On 6th January the company unveiled new tactical radio and waveform products in the guise of its StreamCaster Lite 4200 (SL4200) transceiver.

New ten watt/W and 20W versions of its existing StreamCaster 4200 (SC4200) and StreamCaster 4400 (SC4400) radios were also revealed. These latter two radios each have several frequency options across wavebands of 400 megahertz/MHz to 5.875 gigahertz. Both are outfitted with the company’s Mobile Networked Multiple In/Multiple Out (MN-MIMO) waveform.

Silvus is expanding the MN-MIMO waveform to encompass new capabilities like spectrum monitoring and interference avoidance/cancellation.


Silvus stated in a press releases that the SL4200 is the “smallest and lightest radio Silvus has ever offered;” optimising the radio for size, weight and power constrained applications. The SL4200 is available in S-band (2.2GHz to 2.5GHz), Federal C1 band (4.4GHz to 4.94GHz) with an L-band variant under development.

Weighing a mere 105 grams (0.23 pounds), the SL4200 consumes 4.8W to 17W of power. The MN-MINO waveform is installed, along with DES56 and optional AES-256 encryption. Data rates of 20 megabits-per-second are achievable with the radio which has channel bandwidths of 125MHz, 2.5MHz or five megahertz. Jimi Henderson, Silvus’ vice president of sales told Armada that the SL4200 is “brand new and we will start accepting orders from 1st April.”

Mr. Henderson continued that the new spectrum monitoring feature “allows every radio in the network to continuously monitor up to six channels across the bands the radio supports.” This means that “if the operator identifies a cleaner channel than the one the network is currently operating on, they can move the entire network with a single click or tap.” These waveform enhancements are available as options for the existing SC4200 and SC440 radios.
