At 39.2mm x 13.0mm in total size (including connectors!) this balun was designed to be light in weight and light on your wallet. Very low insertion loss of -1.3dB (typical), with a maximum input power of +28dBm. Designed for HF applications, but specifications are accurate to frequencies up to 90MHz+. Review: Tiny but effective bit of kit! - Great little item that appears to do exactly what it is supposed to. I have used it to match my long wire antenna to an SDR and all appears fine. Unsure of the technical details of the Balun, so I leave that to better informed individuals to provide... Overall very happy! Review: It arrived and it works! - This little balun seems to work perfectly OK, and was a stopgap purchase until I can find time to build a much larger Antenna Tuning Unit. Ideal for someone experimenting with SDR dongles. ## Features - 1:9 HF antenna balun for long wire antennas; includes excellent ESD protection on input. - Excellent specifications & low insertion loss.Only 39.2mm x 13.0mm and 5g! - Great match for attaching a long wire to the Ham It Up. - Only 39.2mm x 13.0mm and 5g! - Fully assembled, and easy to use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00R09WHT6 | | Best Sellers Rank | 66,011 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 343 in Network Antennas | | Guaranteed software updates until | unknown | | Item model number | Balun One Nine | | Manufacturer | NooElec | | Product Dimensions | 3.99 x 0.99 x 0.99 cm; 6 g | ## Product Details - **Antenna:** Radio - **Brand:** NooElec - **Colour:** ['Grey'] - **Impedance:** 50 Ohms - **Manufacturer:** NooElec - **Number of channels:** 1 - **Number of items:** 1 - **Product dimensions:** 40L x 10W x 10H millimetres - **UPC:** 616469145796 ## Images ![NooElec Balun One Nine - Tiny Low-Cost 1:9 HF Antenna Balun with Antenna Input Protection for Ham It Up, SDR and Many Other Applications! - Image 1](https://m.media-amazon.com/images/I/81J9WqJs7gL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tiny but effective bit of kit! *by P***S on 29 December 2017* Great little item that appears to do exactly what it is supposed to.
