Military Specification Standards for Two Way Radios

Articles

To achieve standardization in the products used by the military and other government organizations, the U.S. Department of Defense (DoD) established rigorous standards known as Military Standards (MIL-STD) or Military Specifications (MIL-SPEC). These standards ensure that products, including two-way radios, meet stringent criteria for performance, durability, and reliability in demanding environments.

What Are Military Standards (MIL-STD/MIL-SPEC)?

Military standards are comprehensive guidelines developed by the DoD to ensure products meet specific requirements for defense-related operations. These standards are designed to guarantee that products are:

Commonality: Ensuring products can be used interchangeably across different military branches and units.
Reliability: Products must perform consistently under extreme conditions.
Compatibility: Products should work seamlessly with existing systems and equipment.
Durability: Products must withstand harsh environments and rough handling.

Two-way radios that meet MIL-STD requirements are tested against a range of environmental and operational conditions, including:

Vibration: Radios must endure constant vibrations without performance degradation, simulating the conditions found in military vehicles or aircraft.
Rain: Radios must remain functional in heavy rain, ensuring clear communication in adverse weather.
Salt Air: Radios must resist corrosion when exposed to salt-laden air, typical in coastal or marine environments.
Sand/Dust: Radios must function in sandy or dusty conditions, such as deserts, without internal components being compromised.
Shock (Dropping): Radios must survive drops from certain heights, simulating accidental falls during use.
Humidity: Radios must operate effectively in high-humidity environments, preventing moisture from interfering with electronic components.
Temperature Extremes: Radios must function in extreme hot or cold conditions, reflecting the diverse climates in which military personnel operate.

MURS Radios and Military Use

Multi-Use Radio Service (MURS) radios are a type of two-way radio that operates on specific VHF frequencies and is notable for not requiring an FCC license for use. Interestingly, MURS radios can be used by military personnel without the need to file a DD1494 (frequency allocation and assignment request), making them a flexible and accessible option for certain military communications.

The Importance of IP Ratings

In addition to MIL-STD, you may encounter radios with an Ingress Protection (IP) rating. The IP rating system is an international standard that indicates how well a product's enclosure protects against intrusion from foreign objects like dust and moisture.

An IP rating consists of two digits:

The first digit (0-6): Indicates protection against solid particles, such as dust. A higher number signifies better protection.
The second digit (0-9): Indicates protection against liquids, such as water. A higher number indicates better resistance.

For example, a radio with an IP55 rating offers:

Dust Protection (5): The device is protected against the amount of dust that could interfere with its operation, though it is not completely dust-tight.
Water Protection (5): The device is protected against low-pressure water jets from any direction, such as water sprayed from a nozzle.

Why Choose MIL-STD and IP-Rated Radios?

Purchasing a two-way radio that meets MIL-STD or has a high IP rating ensures you are investing in a product designed for rigorous use. These radios are built to withstand the challenging environments typical of military, industrial, and outdoor applications. Whether facing extreme weather, rough handling, or exposure to dust and moisture, MIL-STD and IP-rated radios provide reliable communication when you need it most.

Maximize the Potential of Your Current Radios

Two-way radios are excellent for mobility, but sometimes fixed communication devices are a more reliable choice. With fixed devices, you eliminate the risk of them being misplaced or unavailable when emergency communication is needed most.

You can enhance your communication setup with two options: wireless call boxes and base station intercoms. Both can be easily integrated with your existing radios. Just provide us with your radio's frequency and privacy code, and we'll program these devices to work seamlessly with your system. Privacy codes, also known as tone codes, interference eliminator codes, or color codes (depending on the manufacturer), ensure your radio only activates when the correct code is transmitted, preventing unwanted noise.

Wireless Call Boxes - A wireless call box functions as a two-way radio enclosed in a waterproof housing, suitable for indoor and outdoor use, even in wet conditions. Mounted on a wall or surface, they are always ready for communication and can’t be misplaced.

Desktop or Wall-Mounted Base Station Intercoms - These intercoms are designed for indoor environments. They can be placed on a desk or mounted on a wall, providing the same functionality as a mobile two-way radio but with the added benefit of always being powered and ready to use.

Other Devices - In addition to two-way radios, various UHF-compatible devices can enhance communication capabilities. One popular option is the Wireless PA receiver, which captures radio transmissions and broadcasts them through an amplified horn speaker for wider coverage. Wireless doorbells and customer service callboxes are also available, further extending the functionality and versatility of two-way radios in various environments.
