Mostly 3D Printed Discone Antenna - MCAD - Render - 6

I have designed and built this mostly 3D printed discone antenna mainly because I needed a wideband antenna for my SDR ( Software Defined Radio) to receive signals from my own RF projects (like LoRa) and to receive other signals ( Ham Radio, Airband etc.).…
