Portable UHF SATCOM Short Dipole Antenna Description
Leadtime: 2 weeks ARO
This UHF SATCOM Short Dipole Antenna was designed for applications where a simple lightweight, very rugged, compact UHF antenna is needed. This product can mount directly onto the connector of a radio set, strapped to equipment, or embedded into non-metallic structures (for advice on embedding or permanent integration into equipment, contact us). Three connector versions are offered to accommodate the various portable radios existing in the field: N, BNC (PRC-117 connector) and TNC (PRC-148 or MBTR connector). Alternatively, you may strap the UL-3001-340S to your backpack (as far away from your body, minimizing the SAR* for your safety, and any metallic surfaces as practicable). Velcro type straps, such as our ACC-00010, allow for quick deployment and stow. The two Revisions of the UL-3001-340S antenna differ by their bandwidth. Revision A is the latest implementation, which was broadbanded to accommodate both legacy and new waveform MUOS payloads.
This antenna provides a DC short circuit to help protect radio electronics connected to it from electrostatic discharge (Rev A also isolates the center pin from the DC shunted ESD currents). At its UHF passband of 243-320 MHz, the nominal impedance is 50 ohm, with a maximum VSWR of 3.
* SAR = Specific Absorption Rate, which refers to the amount of emitted radio energy absorbed by human tissue near an antenna
