The AN/PRC-158 (Army Navy / Portable Radio Communications) is a multi-channel manpack radio designed to provide advanced, secure, and flexible communication for modern battlefield operations. Part of the L3Harris Falcon IV family, it is engineered to bridge the gap between air and ground forces. Operational Role and Capabilities The radio is primarily used for tactical operations requiring simultaneous voice and high-speed data across multiple channels. Dual-Channel Operation : Unlike older single-channel radios, the PRC-158 features two independent channels, allowing operators to monitor and transmit on different frequencies or waveforms at once. Frequency Range : It covers the full 30–2500 MHz spectrum, supporting VHF, UHF, and satellite communications. Interoperability : It is designed to replace legacy systems like the AN/ARC-201D SINCGARS in aircraft like the Chinook, significantly expanding PACE (Primary, Alternate, Contingency, Emergency) planning capabilities. Standard Manual & Training Structure Official technical manuals (TMs) for this equipment are often restricted to military personnel, but a standard manual or handbook generally follows a specific instructional flow: System Description : Overview of components, including the receiver-transmitter (R/T) unit, antennas, and batteries. Installation : Guidelines for mounting the unit, whether in a manpack configuration or within vehicular docking stations (e.g., AN/VRC-T139). Operation : Procedures for power-on self-tests (POST), loading cryptographic keys (Fill), and selecting pre-programmed presets. Waveforms : Instructions on using specific networking waveforms such as TrellisWare TSM for mobile ad-hoc networking (MANET). Troubleshooting : Basic PMCS (Preventative Maintenance Checks and Services) to resolve power, signal, or antenna issues. Key Configurations Manpack : Portable configuration including the radio unit, a battery box, and flexible antennas for field use. Vehicular : Mounted in a vehicle rack that provides constant power and typically connects to high-gain external antennas for extended range .
The AN/PRC-158 Multi-channel Manpack (MCMP) is a software-defined radio (SDR) designed by L3Harris to provide simultaneous, dual-channel connectivity across a broad frequency range (30–2500 MHz). Its technical manual details a system that is 30% smaller than legacy manpacks while offering enhanced encryption and networking for forward-deployed forces. Key Technical Specifications The AN/PRC-158 is built for versatile communication across multiple domains: Channels: Two independent channels that can transmit and receive simultaneously. Frequency Range: 30 MHz to 2.5 GHz. Power Output: Narrowband: 10 W. SATCOM: 20 W. Wideband: 20 W peak / 10 W average. Waveforms Supported: Includes SINCGARS, HAVEQUICK I/II, VHF/UHF LOS, HPW, SRW, and MUOS-ready hardware for satellite communication on the move. Security: Sierra™ II-based Type 1 encryption, certified for TOP SECRET data and voice. Operational Configuration The user manual and technical guides outline the radio's physical and operational setup: Physical Footprint: It weighs approximately 12.7 lbs with a battery and measures 3.5" H x 7.36" W x 14.25" D. Power Requirements: Operates on 19–34 VDC and is compatible with standard military batteries such as the BB-2590/U . Interfaces: Features standard 6-pin audio connectors per channel and multiple data ports, including USB, Ethernet, and RS-232 . Controls: A primary function knob with positions for OFF, ON, LD (Load), and Z (Zeroize). System Integration & Maintenance Network Planning: The radio is managed through the Communications Planning Application (CPA) and is compatible with the Joint Enterprise Network Manager (JENM). Versatility: Beyond manpack use, it can be integrated into vehicular mounts (like the AN/VRC-124) or airborne platforms such as the CH-47 Chinook . Environmental Standards: It is tested to MIL-STD-810G , ensuring durability against shock, vibration, and immersion in up to 2 meters of salt water. For more specific procedures like zeroizing or advanced waveform loading, you can refer to official field manuals or the U.S. Army Smart Books . AN/PRC-158 Multi-channel Manpack (MCMP) - L3Harris
Technical Write-Up: AN/PRC-158 Manpack Radio 1. System Overview The AN/PRC-158 is a next-generation, multi-mission manpack radio designed for secure, reliable tactical communications. It is part of the U.S. military’s Handheld, Manpack, and Small Form Fit (HMS) program. Developed primarily by Thales Defense & Security, the AN/PRC-158 serves as a critical node in the tactical network, providing warfighters with Line-of-Sight (LOS) and Beyond-Line-of-Sight (BLOS) capabilities in a single, ruggedized chassis. Unlike its predecessors, the PRC-158 is designed to support the Mobile User Objective System (MUOS) waveform, which provides cellular-like coverage for troops in the field, significantly extending communication ranges without relying on tactical satellite relays that require precise pointing. 2. Technical Specifications The AN/PRC-158 improves upon earlier iterations (such as the PRC-148 or PRC-152) by incorporating wideband networking capabilities and modernized satellite connectivity.

Dimensions & Weight: Approximately 8.5 inches tall (without battery) and roughly 6-8 lbs depending on configuration. Security: Built-in Type-1 NSA-approved cryptography (AES-256 and legacy algorithms like KY-57/KY-58 compatibility).
3. Operational Capabilities Line-of-Sight (LOS) In LOS mode, the radio functions similarly to traditional combat net radios. It transmits VHF and UHF signals between units that have a clear path to one another. This is the standard mode for tactical voice communication within a platoon or company. Beyond-Line-of-Sight (BLOS) via MUOS The defining feature of the PRC-158 is its integrated MUOS capability. MUOS utilizes a constellation of geosynchronous satellites. Unlike legacy SATCOM which requires the user to point an antenna at a satellite (often requiring them to remain stationary), MUOS provides "on-the-move" (OTM) communication.
User Experience: The operator can communicate over thousands of kilometers using a standard whip antenna while moving, similar to using a cell phone. Antenna: Typically utilizes a dual-polarized whip antenna optimized for L-band uplink while maintaining V/UHF LOS capabilities. LCD screen icons (TX
Crossbanding The AN/PRC-158 can act as a gateway. It can receive a transmission on one waveform (e.g., SINCGARS VHF) and retransmit it on another (e.g., MUOS SATCOM). This allows dismounted troops to communicate with command elements over the horizon without specialized infrastructure. 4.
