    Model UL-1501-B347 is a lossless* (efficient), passive broadband antenna suitable for general two-way communications at any frequency from 500 MHz to 3.0 GHz, without any need for tuning. Other applications of this antenna include omnidirectional broadband receiving, spectrum monitoring, scanners, and low dispersion jamming. Its 50 Watt handling capability allows its use as a single-port, multi-function antenna, enabling multiple, simultaneous communications/RF operations, through the use of adequate diplexers.

    Operation beyond 3 GHz is well supported by this design; however, variations in gain are to be expected, as with any large/travelling wave antenna. Operation below 500 MHz is supported in receive only applications, or at low power (under 5 Watts), with the aid of impedance matching. Gain drops rather rapidly below 300 MHz (as with any other antenna of comparable size). Contact Engineering for further support. Fixed mounting options are available.

    * NOTE: by "lossless", we imply that no resistor network (attenuator) is used to achieve broadband matching
