## Description

Omnidirectional wideband passive UHF Antenna for Evolution Series

Review: Worked with my PSM 300 - I combined this with a pair of Shure PSM 300 units and they worked great.
Review: Great Signal gain indoors - This is being used in a church auditorium, where we have had a number of problems with signal quality. I placed the antenna in a distant part of the room where signal was dropping below 25 on the Sennheiser EW100 G3 receiver, and switched to this antenna, signal rose to a solid 40. Just what we needed.
