Custom cable solutions for anything SC4200 or SC4400 radios need: primary-port ethernet in variable lengths, UXV and MPU5 bridges, EUD and Nett Warrior leads, 2590 and vehicle power, battery eliminators, an IP67 hand mic, and an austere solar kit are some of our common items. Built by Protocable in Auburn, Washington and shipped globally.
Silvus is focused on making the best radio they can, and they have deep experience and talent supporting them. Protocable's field experience complements the radio technology by giving users streamlined and durable kitting solutions.
Radios are regularly limited by their accessory suites. We build robust options for hard use, with operator needs driving the design.
Primary port to RJ-45, UXV and MPU5. Auxiliary port to USB-C and Nett Warrior. Modular power from a single or dual 2590, a vehicle cigarette socket, an AC/DC supply, a battery eliminator or a solar scavenger. When a unit standardizes on Silvus, the whole accessory list comes from this page.
The cables below are listed most-fielded first, straight from our shipment history.
Braided, PUR-jacketed, US-manufactured cable across all builds. Overmolded aluminum 2590 terminations with tie-down loops on the power side.
ODU primary and auxiliary plugs, Switchcraft EN3 modular power, Nett Warrior, UXV and 2590: Standardized around the family of accessories most commonly fielded, no adapters in the loop.
In-house manufacturing means a prototype becomes a unit-wide buy without a distributor's queue.
The fourteen most common part numbers, ordered by the quantity units have actually taken delivery of. Blue markers are the Silvus side of each cable, gold markers are the other end.









Every cable terminates in the connector the equipment already uses. Overmolds are color-coded where two ends could be confused, and strain relief comes straight out of the connector body.







Power the radio while the battery charges. Solar in, vehicle in, or supply in; StreamCaster out, without a break.
