Linear vs Circular Polarized Antennas

Linear antennas are simple, cheap, light, durable and work well enough. They do suffer from polarization and multi-path interference. These issues are mitigated with circular polarized antennas. On the sending side, circular polarized antennas send usable signals regardless of orientation. On the receiving side, they capture polarized signals and– when using matching circular polarized antennas– drop multi-path interference leading to a cleaner picture. In the above video from Neil DeLillo, you can see this difference in actual real-world use. Here’s the full article that explains the difference in detail. Basically, it’s weight/durability vs picture quality.

Fixing A Broken VTX

I burntoutmy VTX03 during a crash so I got and installed a VTX01 on my Tiny Whoop. But this afternoon, I was inspecting it when I noticed a burnt component. At first, I thought it was a capacitor. First step is to find out the part number. But the component was burnt beyond recognition. So I searched for photos that show the part and found this:
After some more digging, I found out that the burnt component is actually a resistor, a zero-ohm link. Link, that’s like connect, bridge. So I just simply bridgedthe terminals of the burnt resistor with a bit of solder.
And just like that the VTX03 lit up back to life!
