Wideband passive antenna for sound bags

The BETSO BOWTIE is a compact passive wideband antenna designed for use on a sound bag. Its 470-700 MHz operating range, horizontal omnidirectional pattern and built-in 700 MHz low-pass filter help maintain reliable reception in crowded RF environments.

The sealed IP65 construction uses CNC-machined anodised aluminium and glass-reinforced epoxy laminate. Each BOWTIE is supplied as a working kit with bag antenna holder plus short BNC-BNC and BNC-SMA right-angle cables.
