UC-3004-581R Data

Smart Spider Antenna Description

Smart Spider™ Antenna model UC-3004-581R is a lightweight, tactical, low observable, compact UHF Satcom-On-The-Move Active X-Wing antenna system. It enables dismounted UHF Satcom, while dynamically engaged in operations. In other words, this SOTM Antenna enables infantry & special operations without a pause.

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.

Key features of this SOTM Antenna

Small and Lightweight, can be stowed in a small pouch (6" x 6" x 2" or 15 cm x 15 cm x 5 cm)

Difficult to see/spot at a distance

One button and automatic-ON operation (press and forget)

Self-powered (a 4 hour charge will typically support continuous operation for up to 10 days)

Auto Two-mode internal charger (RF Quiet/Voltage tolerant) supports charging from 5-16 V sources, observes USB-2 charging limits when powered from a standard USB port

Built-in solar cell extends operation lifetime

Compatible with the following accessories: High Gain Mount (ACC-0581), doubles the gain (adds 3 dB) when installed on a metal surface larger than 28"/70 cm x 28"/70 cm, or on the ground Suction Cup Mount (ACC-0002), to attach to non-metal and metal, smooth surfaces Magnetic/Mag Mount (ACC-0003-581 or ACC-0001-581), to attach to ferrous metal surfaces Bolt-on, AV 2090, 4 hole pattern compatible, direct Vehicle Mount (ACC-0008) Universal Antenna Ground Mount Stake (ACC-0013) Standard Camera Tripod Make your own bracket - all you need is a 1/4" (6.4 mm) hole

Antenna elements may be webbed onto a backpack for Infantry, on-foot SOTM (Satcom-On-The-Move)

In its normal orientation (solar cell/display at top), the UC-3004-581R is RHC Polarized (Right Hand)

May be transported on passenger aircraft, or shipped via common carrier without any special UN markings

Waterproof to 3 m (6 ft)
