Now we get great in-ear sound, vocals are getting tighter and I’ve even gotten the guitarist to use them. Makes a huge difference. 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 | #392 in Radio Antennas | | Brand | Sennheiser | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 49 Reviews | | Global Trade Identification Number | 00615104046450 | | Impedance | 140 ohm | | Item Type Name | Wireless Microphone System | | Item Weight | 10.24 ounces | | Manufacturer | Sennheiser | | Mfr Part Number | 004645 | | Model Number | 004645 | | Number of Channels | 1 | | Number of Items | 1 | | Number of Packs | 1 | | UPC | 615104046450 | | Unit Count | 1 Count | | Warranty Description | 2 years parts & labor. | ## Product Details - **Antenna:** Radio - **Brand:** Sennheiser - **Color:** Black - **Global Trade Identification Number:** 00615104046450 - **Impedance:** 140 ohm - **Manufacturer:** Sennheiser - **Number of Channels:** 1 - **Number of Packs:** 1 - **UPC:** 615104046450 - **Unit Count:** 1 Count ## Images ![Sennheiser Pro Audio A1031-U Wideband Passive Omnidirectional UHF Antenna for Evolution Series - Image 1](https://m.media-amazon.com/images/I/614cz-cYYuL.jpg) ![Sennheiser 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 ### ⭐⭐⭐⭐⭐ Overcome interference *by C***N on August 15, 2026* I haven’t taken this to a gig yet, but our practice space is next to a high-gain ground antenna, and since I started using this we’ve had none of the glitches and dropouts in our IEM system that used to make me question my IEM investment.
