    Smart Spider™ Antenna model UC-3004-581R is a lightweight, tactical, low observable, compact UHF Satcom-On-The-Move antenna system, enabling dismounted UHF Satcom while dynamically engaged in operations. The polarization of this antenna is Circular (CP), intended primarily for communications through satellites. Its radiating elements are flexible and are difficult to see at a distance, from any view angle. The Smart Spider™ Antenna can be stowed in a small pouch, and/or webbed onto a backpack. Compatible with UFO, MUOS and Legacy Satellites.

    Additional information on the UC-3004-581R Smart Spider™ Antenna, including customized variants and expanded features, is available per special request. Contact us at .
