    SmartSpider® Antenna Description

    Smart Spider® Antenna model UC-3004-581R is a Patented, lightweight, tactical, low observable, compact UHF Satcom-On-The-Move Active X-Wing antenna system. It enables dismounted UHF Satcom and IBS/CIB reception, while dynamically engaged in operations. In other words, this SOTM Antenna enables infantry & special operations without a pause. The Smart Spider® is a great tool for the collection of UHF Satcom Integrated Broadcast Service (IBS), Common Interactive Broadcast (CIB) signals for Infantry and expeditionary forces.

    The polarization of this antenna is Circular (CP), intended primarily for communications through UHF MUOS, UFO and Legacy Satellites. It spans the spectrum from 243 MHz to 320 MHz (243-320 MHz) for DAMA/IW and 300 to 320 MHz/360 MHz to 380 MHz (300-320/360-380 MHz) for WCDMA. 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 webbed onto a backpack.

    A Satcom-On-The-Move Active X-Wing

    The Smart Spider® contains an embedded Low Noise Amplifier that provides additional sensitivity and gain needed to close the link, while remaining omnidirectional. Its Intelligent Antenna features and internal, redundant rechargeable batteries provide the needed power for up to 10 days of continuous operation on a single 4-hour charge. It automatically switches between transmit and receive operation for full two-way DAMA/IW use, without any user intervention. Two-way WCDMA operation is supported in passive mode only.

    Upcoming Smart Spider™ Plus and Additional Capabilities

    Smart Spider™ Plus: We are currently augmenting the UC-3004-581R UHF Satcom antenna to add L-/S-/C-/X-/Ku-band cross-band capabilities to existing and legacy field radios, useable in mounted and dismounted configurations. The Solar Cell is being removed to add this new functionality. Contact us for additional information. The release of these new capabilities is based on interest or need.

    Additional Capabilities: Further information about the UC-3004-581R Smart Spider™ Antenna, including additional capabilities, expanded features and customized variants is available per special request. Call us at 954-345-5000, or email us at .
