Astor IV Dual Pods

Astor dual wing pods and radomes originate from the AN/ALQ-503 pod which is modified and built ITAR free in Sweden.

The Pod shell flies on many civil and military aircraft. The Astor IV pods should hang in two pylons as far out on each wing as possible in order to optimize antenna coverage and use Rx Overlook and gain isolation for side/back lobe jamming with parallel receive and transmit.

The pod is ram air cooled and does not require any special cooling during flight and continuous operation. When stationary the complete system is capable of running continuously with additional ground cooling equipment. 

The inside of the pods is modified to allow Astor modular LRUs to be carried on and under a sliding shock absorbing tray. The tray has an additional internal channelized ram air flow for more effective cooling where needed. Shock absorbing dampers are mounted on and under the tray to minimize vibrations for the LRUs.

Astor Radomes:


All radomes fulfill ER-953-B insertion loss by using the latest modern radome material with Low Dielectric Epoxy / Quartz Fabrics.

The cyanate ester prepreg resin system used is unique in the industry in that it is able to achieve an extremely high level of cure conversion. This level of conversion provides optimal mechanical properties, high radiation resistance, low moisture absorption, and low outgassing while retaining unparalleled toughness, stress-free temperature, and long out time. The resin system excels in its ability to resist micro-cracking, even when subjected to thermal cycling and high levels of radiation exposure.

  • High radiation resistance
  • Low micro-cracking even under severe thermal cycling
  • Low moisture absorption
  • Low dielectric constant and dissipation factors
  • Low stress-free cure temperature with high level of cure
  • Outstanding mechanical properties
