    UHF SATCOM Antenna Description (Mini, Midi and Full sizes)

    UHF SATCOM Antenna model UC-3004-381 is a lightweight, tactical, compact Turnstile/X-Wing antenna system. The polarization of this antenna is Circular (CP), intended for communications via MUOS satellites (DAMA/IW/WCDMA). This antenna is approximately half the size of a normal X-Wing antenna (Basic size version). However, it offers comparable gain to its full size counterpart. Its Mini version's half size dimensions make it ideal for tactical applications, where low observability is important. It will also serve to spoof opposing forces and intelligence efforts. They will be believing traffic through the antenna is occurring at much higher frequencies, due to its small size.

    For applications where antenna size and/or observability is less critical, we offer two other Sizes (or Versions): Extended (Midi) and Full, with increased performance. The following photo shows all three sizes for comparison. Detailed specifications for each Size/Version is provided below. You may select the desired Size/Version through the "Version" dropdown menu at the top of this page.

    Three versions of the UC-3004-381 X-Wing Antenna we offer

    Important X-Wing Polarization Note:

    RHCP Region: Where the satellite should be when using a UC-3004-381R/RE/RF X-Wing Antenna

    The region opposite the RF connector has the specified polarization (Green, RHCP in the photo above). The polarization is opposite in the hemisphere below the green region. In the above image, the region below the antenna would be LHCP (Left Hand Circular Polarized). Thus, if you intend to use the antenna in an upside-down configuration, such as an UC-3004-381 + suction cup (ACC-0002) attached to the cockpit of an aircraft (RF connector normally pointing up to the sky), you will need to specify the polarization as LHCP. Contact us if in doubt.

    SATCOM Antenna Design Modularity and Implementation Philosophy

    The design of this Mini UHF X-Wing Antenna is modular. This enables you to use one antenna in multiple ways. For example, mount it on a vehicle, using the High Gain Mount, ACC-0005 and either a magnet (ACC-0003) or a suction cup (ACC-0002). For a more permanent installation, use the standard X-Wing bolt mount (ACC-0008, compatible with AV 2090, 4 hole pattern). After reaching your target area and you dismount the vehicle, you may remove the antenna (with or without the High Gain Mount). Then, attach it to your radio with a Coaxial Cable Assembly for portable use (click here for more cable choices).

    Additional Capabilities and Variants

    For a lighter, less observable version of this antenna, which will fit a 4" (10 cm) x 4" (10 cm) pouch, or the pockets of a trouser, see UC-3004-481 Tacsat Antenna. If you need on-foot (dismounted) satellite access for infantry/special operations, you might prefer our UC-3004-581 Smart Spider(TM) Antenna instead. It has a built-in LNA that kicks-in during DAMA/IW/IBS receive, to boost downlink signals, providing between +7 dBic to over +13 dBic effective RX gain, depending on the field radio used.

    Contact us for further information about the UC-3004-381 Antenna, or any of the cited options. This includes additional capabilities, expanded features and customized variants, which are available per special request. Call us to discuss your requirements at 954-345-5000.
