1.5M Vehicle Mounted Tri-Band Satellite Antenna for  Military and Government

Multi-Band Antenna System

Unparalleled Performance in secure communication environments The Holkirk DRM150 is a cutting-edge, multi-band antenna system meticulously designed for the demanding requirements for secure multi-network communication, the DRM150 is your reliable partner for communications in any corner of the globe. 

Next Generation Land Terminals

Holkirk Next Generation Land Terminals leverage the unique strengths of Multi-band operation to create a hybrid architecture aimed at enhancing connectivity and communication resilience.

By switching between X, Ku and Ka-band frequencies, the systems can optimise data transmission based on real-time conditions, delivering reliable, high-speed communication services across diverse environments. Furthermore, these terminals integrate cutting-edge technologies like advanced auto frequency band detection and adaptive RF parameter selection to ensure your modem is always set to the correct receive configuration.

Another impressive capability of the Holkirk terminals is their non-Geostationary inclined orbit tracking function. This feature is integrated across the entire range, enabling the terminals to track satellites in inclined orbits.

Simple ‘no-tools’ change over between operational frequency ensures quick and effective band selection with minimal down time and effort in the field.

These features ensures seamless coverage and robust performance, positioning Holkirk Next Generation Land Terminals as a formidable player in the next-gen SATCOM landscape.

COMPACT
The DRM antenna is an ultra-compact tri-band system which encompasses the drive control, positioning hardware and beacon receiver into the fully sealed and aerodynamic antenna enclosure, making the system a robust standalone sub-assembly ready to install onto almost any vehicle.

VERSATILE
The multi-band operation has been designed for effortless change over in the field. The feed, BUC and waveguide for each band is mounted on a simple and quick interchange cartridge which means the only connections you need to make are power, L-Band and control.

EASE OF USE
There are no tools required to change the band of operation. All satellite acquisition commands are performed via the simple and easy to use antenna controller unit. The DRM system is equipped with a GPS receiver, electronics compass and levelling inclinometers.

The AIM MOBILE antenna controller is an integral part of the DRM150, designed to make satellite acquisition seamless and user-friendly. The AIM MOBILE will automatically sense the frequency of the selected feed frequency and adjust all the satellite acquisition parameters to allow fast and simple search and lock of any satellite network

Controller Highlights

  • User-friendly interface: Guides users through the acquisition process with step-by-step graphics
  • Versatile: Suitable for users with varying levels of training
  • Customisable: Engineers can alter acquisition data as needed
  • Compatibility: Can be used on a range of Holkirk products with auto-pointing capabilities
  • Inclined orbit tracking with toastrack or TLE data
  • Satellite roaming with full OpenAMIP compatability

 

 The AIM MOBILE controller is a testament to Holkirk’s commitment to innovation, providing a fully mobile ACU that simplifies the acquisition process for all users.
