    A broadband, rugged, mobile radio antenna designed to service two contiguous TETRA UHF Bands used in EMS (Emergency Medical Services), Law Enforcement, Government and Civil services, and featuring a DC grounded radiating element. With modest dimensions of 1.5"/4 cm (OD) x 4"/10 cm (height), this antenna radiates with a typical peak omnidirectional gain of +4 dBil, when mounted on a large metal surface of at least 16"/40 cm radius. Internally, the radiating element is DC grounded to help protect the transceiver from nearby, but not direct ElectroStatic Discharge (ESD).

    The UL-4050-334 was designed for dual band TETRA antenna applications in Europe. The US version of this wideband antenna is our model UL-4500-334, which covers the spectrum of 430-470 MHz.

    NOTES:
    • Requires a ground plane (normally mounts on a metal body)
    • Its large bandwidth allows this antenna to be used for the surveillance of signals ranging from 200 MHz to 1 GHz
    • Specifications and prices are subject to change without notice
    • Patent Pending
    • CAUTION: In the market, there are many sources of uncontrolled NMO mounts and cable assemblies. Although we have found that most "low cost" NMO connectors available can perform well, their cable assemblies tested poorly, particularly above 700 MHz, due to a low degree of "RF care" when connecting the coaxial cable to the NMO connector. Observed carelessness results in the accidental addition of a stray series inductance, with a reactance comparable to the 50 ohm input impedance, generally worsening the match seen by the transceiver connected at the other end. However, most cable assemblies acquired and measured, performed reasonably at the lower UHF frequencies (400-512 MHz).
