Description
EasyEDA project for easy and quick build active RA0SMS Mini-Whip receiving antenna. Project includes schematic and PCB with SMA connectors. Version for mounting SMD components. ## Current development progress: [![Progress](https://img.shields.io/badge/Antenna%20Mini--Whip%20%28SMD%29-tested-green.svg)](https://github.com/IgrikXD/Easy-SDR) [![Progress](https://img.shields.io/badge/version-5.0.EE-blue.svg)](https://github.com/IgrikXD/Easy-SDR) [![Bug report](https://img.shields.io/badge/Google%20Form-Create%20bug%20report-red.svg)](https://docs.google.com/forms/d/e/1FAIpQLSeUFM1p15N_vk8X_blSnZp6jPlZe_qRhiRlmntscx6jF2yRqw/viewform?usp=sf_link) **Frequency range:** 10kHz - 30MHz; **Power:** DC 5 - 13 V, 100mA; **RF connector:** SMA; **Feed line:** 50 Ohm coaxial cable; **Used PCB Material:** FR-4; **PCB thickness:** 1.6 mm; **PCB copper weight:** 1 oz; [Easy-SDR project page at GitHub][1] Original schematic: [RA0SMS Mini Whip][2] Buy SDR receiver: [RTL-SDR.COM][3] ## List of changes: Version **5.0.EE**: the RF line width has been recalculated using [Saturn PCB Design V7.08](http://www.saturnpcb.com/pcb_toolkit/). At the moment, the resistance of the RF line is close to 50 Ohms. ## How to contact me? - E-mail: igor.nikolaevich.96@gmail.com - Telegram: https://t.me/igrikxd - LinkedIn: https://www.linkedin.com/in/igor-yatsevich/ [1]: https://github.com/IgrikXD/Easy-SDR [2]: http://www.ra0sms.ru/p/the-active-antenna-mini-whip-10-khz-30.html [3]: https://www.rtl-sdr.com/shop/
