Alpha Antenna Digital Mode MiniLoop Antennas are wideband magnetic loop antennas that can be deployed in two different physical arrangements to optimize efficiency. They provide coverage ranging from 0 to 1,500 miles (2,500 km) within the frequency range of 10 to 54 MHz, exhibiting the following functional characteristics:

• RX with low noise characteristics from 1.8MHz through 1GHz and higher frequencies.

• TX support without a tuner for Digital Modes from 10 to 54MHz.

Deployment and Usage

The Mini-Loop can be deployed in two ways using the hardware included. Deployment Option B, which is an expanded double loop configuration, provides the most efficiency. Option A is a single nested loop

• Deployable with quantum and/or fixed/spread-spectrum digital mode equipment.

• Missions that require digital Ground-wave and/or Skywave HF communications.

• Useful when an isolated solution is required that does not need a counterpoise.

Specifications:

Frequency Range

• Receive: 1.8MHz - 1GHz

• Transmit: 10 - 54MHz - Digital Modes, No tuner required

• Maximum Input Power Rating: 25W* - Digital Modes only.

* Including but not limited to the MIL-STD-188 M110a digital communications mode that is rated at 25 watts continuous with bursts of 100 watts digital for up to 1 minute using the MIL-STD Data Modem Terminal (MS-DMT) and Automated Message Terminal (AMT) software applications.

USAGE SCENARIOS

Where secrecy is paramount, communication through unseen methods plays a crucial role. Some of the usage scenarios of clandestine antennas include:

1. SCADA

• Context: Protecting infrastructure is key to providing continuity, integrity, and availability.

• Solution:

  • Clandestine Deployment: A small out-of-site antenna is significant to hiding communications capabilities are less likely to be thwarted.

1. Clandestine Communications in Cyber-Denied Environments:

• Context: In an era where internet-based communications are vulnerable to surveillance and attacks, intelligence operatives seek alternative methods.

• Scenario: Imagine a situation where an operative needs to communicate without exposing themselves to internet-based surveillance.

• Solution:

  • Physical Separation: Platforms physically separated from the internet can be used. These platforms are not susceptible to internet-based surveillance or attacks.

  • Radio Technology: Combine modern computer-based software with radio technology.

• Importance: Counterintelligence and law enforcement must adapt to these evolving communication methods.

• Countermeasures: Detect radio-based clandestine communications and secure evidence.

1. Operational Scenarios where concealment and minimizing visibility are critical:

• Inside a Parked Car:

  • Example: Monitoring a nearby building while parked outside.

    • Setup: Transceiver, receiver, and antennas positioned out of sight from windows.

  • Between Floors in an Office Building:

    • Example: Operating from the third floor to the first floor.

      • Setup: Transmitter, receiver, and antennas positioned out of sight carried out of site under clothing.

    • Out in the Open:

      • Example: Providing regional communications support while deployed in the field.

        • Setup: Transmitter, receiver, and antennas positioned out of sight inside a backpack.

Remember, clandestine antennas are designed to operate covertly, avoiding detection by adversaries. Their success lies in striking a balance between effective communication and maintaining secrecy with a right sized antenna.

All of these solutions are possible with the Alpha Antenna Digital Mode MiniLoop Antenna.
