UC-3004-481 Data

Tacsat Antenna Description

Tacsat Antenna model UC-3004-481 is a lightweight, low observable, compact UHF Satcom antenna system. The polarization of this Tactical X-Wing is Circular, intended for communications via UHF MUOS satellites (DAMA/IW/WCDMA). When used on its high gain mount, it can be utilized with UFO and earlier satellites. Its radiating elements are flexible and difficult to see at a distance, from any view angle. The small Tacsat Antenna can be stowed in a very small pouch, or webbed onto a backpack.

UHF Line of Sight communications can be maintained with this antenna. When operated as an intra-team aerial, its circular polarization offers natural diversity, reducing the intensity of multipath. Variants for other operating frequencies may be requested as indicated below.

Key features of this tactical antenna

Small and Lightweight, stows in a typical trouser/jeans pocket, or a small pouch (4"/10 cm x 4"/10 cm)

Difficult to see/spot at a distance

Quick deployment (take out of pocket/pouch, connect to cable and you are ready to communicate)

Modular - one antenna can serve multiple purposes/platforms

Compatible with all the accessories of our UC-3004-381 Mini-UHF X-Wing antennas, which include High Gain Mount (ACC-0005)*, 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-0005 + ACC-0002), to attach to non-metal and metal, smooth surfaces Magnetic/Mag Mount (ACC-0005 + ACC-0003 or ACC-0001), to attach to ferrous metal surfaces Bolt-on, AV 2090-4 hole pattern compatible, direct Vehicle Mount (ACC-0005 + ACC-0008) Universal Antenna Ground Mount Stake (ACC-0013) Standard Camera Tripod (ACC-0005) Make your own bracket - all you need is a 1/4" (6.4 mm) hole

Antenna elements may be webbed onto a backpack for tactical, on-foot COTM (Communications-On-The-Move)

In its normal orientation (connector pointing towards the ground), the UC-3004-481R is RHC Polarized (Right Hand), flip it upside down (connector points to the sky) and polarization will change to LHCP (Left Hand)
