1.5M – Vehicle Mount DSNG Satellite Broadcast Antenna

The Eutelsat Characterised 1.5M DSNG Antenna

Holkirk RM150: The Eutelsat Characterised DSNG Antenna

The Holkirk RM150 is a state-of-the-art DSNG antenna that has been fully characterised by Eutelsat, ensuring it meets the highest standards for satellite news gathering. With its 1.5m high-gain carbon fibre reflector, the RM150 offers exceptional performance in the most demanding DSNG environments.

With excellent attention to mechanical detail and high performing materials selection, the RM series of Antennas will provide many years of continuous service in the harshest of applications.

Versatile

The versatile power-payload of the RM antenna series has been designed to take low power SSPAs or high power TWTs in single thread or 1:1 redundant configuration with power levels up to 400W.

Auto-Acquire

The Satellite Acquisition Controller uses industry standard position transducers and a sophisticated pattern recognition algorithm to confirm and refine its heading information using visible satellites. The controller is mounted on the antenna structure with a separate power supply and control panel in a rack mount unit for mounting within the equipment area. Fast acquisition is less than 3 minutes.

Ease of Use

The system is simple to install, set up and use. Following relocation of the antenna, the system will reliably and accurately locate and lock on to the designated traffic satellite, typically in less than 3 minutes from stowed.

Compact
The RM150 antenna is an ultra-compact roof mount system which encompasses the drive control, positioning hardware and BUC/HPA into the aerodynamic antenna enclosure, making the system a robust standalone sub-assembly ready to install onto almost any vehicle.

Versatile
The versatile power-payload of the RM antenna series has been designed to take low power SSPAs or high power TWTs in a single thread, or 1:1 redundant configurations with power levels up to 400W.

Auto-Acquire
The main reflector is manufactured from high quality carbon fiber. The Satellite Acquisition Controller uses industry standard position transducers and a sophisticated pattern recognition algorithm, to confirm and refine its heading information using visible satellites. The controller is mounted on the antenna structure with a separate power supply and control panel, in a rack mount unit for mounting within the equipment area.

Ease of Use
The system is simple to install, set up and use. Following relocation of the antenna, the system will reliably and accurately locate and lock on to the designated traffic satellite, typically in less than 3 minutes from stowed.

The AIM MOBILE antenna controller is an integral part of the RM150, designed to make satellite acquisition seamless and user-friendly.

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
Customizable: Engineers can alter acquisition data as needed
Compatibility: Can be used on a range of Holkirk products with auto-pointing capabilities

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.
