WARNING! BEFORE YOU POWER UP YOUR HELTEC V4, WATCH THIS VIDEO FIRST. The default antenna that was included in the Heltec V4 is not good. It has a high SWR that can damage your LORA RF module. Check the antenna with your nano VNA before using it to your project and BEFORE you apply power to your Heltec V4. #heltec #meshtastic #hamradio #hamradiooperator #lora
