The Best Antenna Is the One Nobody Sees (Shadow Slot Antenna Build)

Updates (Bonus: you get a PDF Plan for the low power shadow slot when you sign up): https://mailchi.mp/vfcomms/shadow-slot Build video    • This Antenna Shouldn’t Work… But It Does (...   Links to past slot videos:    • Slot antennas   I wanted vertical polarization without the mast, the ground plane, or the "look" of a traditional radio antenna. This led me to experimenting with slot antennas. In this video, I dive into the physics of how a slot antenna works as a magnetic radiator, why precision in geometry matters for high-Q antennas, and the lessons learned from using different materials. We see what happens when you push too much power through thin conductive tape (spoiler: it gets hot!) and how moving to Aluminum Composite Panel (ACP) solves the heat and stability issues. Whether you're looking for a stealthy dashboard mount or a lightweight solution for QRP and SOTA, the slot antenna is a predictable and efficient alternative. In this video: The problem with traditional antennas and ground planes. How a slot antenna creates an electric field across a gap. Testing cheap materials vs. precision aluminum. High-power testing (and what happens when things catch fire). Tips for building your own with Faraday tape or cloth. I need your help! How would you mount this to the roof of a car, especially on non-magnetic surfaces? Let me know your ideas in the comments. 73, Ben (VE6SFX)
