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. ## Features - Suitable for use with a UHF receiver in closed rooms - Can be used as a transmitting device - Suitable for use with EM 3031-U, EM 3032-U, EM 3532-U, EM 1046-U, EM 1031-U, and all stationary evolution wireless receivers - Country of origin is Germany ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0010CIIJM | | Antenna | Radio | | AntennaDescription | Radio | | Best Sellers Rank | #442 in Radio Antennas | | Brand | Sennheiser | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 43 Reviews | | Global Trade Identification Number | 00615104046450 | | Item Type Name | Wireless Microphone System | | Item Weight | 6.4 ounces | | Manufacturer | Sennheiser | | Mfr Part Number | 004645 | | Model Number | 004645 | | Number of Channels | 1 | | Number of Items | 1 | | UPC | 615104046450 | | Unit Count | 1.0 Count | | Warranty Description | 2 years parts & labor. | ## Product Details - **Antenna:** Radio - **Brand:** Sennheiser - **Color:** Black - **Global Trade Identification Number:** 00615104046450 - **Manufacturer:** Sennheiser - **Number of Channels:** 1 - **Number of Items:** 1 - **UPC:** 615104046450 ## Images ![Pro Audio A1031-U Wideband Passive Omnidirectional UHF Antenna for Evolution Series - Image 1](https://m.media-amazon.com/images/I/61tkXQ2NCeL.jpg) ![Pro Audio A1031-U Wideband Passive Omnidirectional UHF Antenna for Evolution Series - Image 2](https://m.media-amazon.com/images/I/51netGS5P8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked with my PSM 300 *by A***R on July 31, 2024* I combined this with a pair of Shure PSM 300 units and they worked great. ### ⭐⭐⭐⭐⭐ Great Signal gain indoors *by R***S on December 12, 2016* This is being used in a church auditorium, where we have had a number of problems with signal quality.
