NEW DJI O3 Range & Penetration | Improve FPV Drone Signal Testing | DIY & TrueRC High Gain Antennas

In this video were testing my latest FPV Long-Range High-Penetration DIY antenna setups. I'm using DJI here, but this would work well on Analog, HDZero, and WalkSnail systems as well.

How do you improve FPV Range & Penetration? Do you need expense antennas? Let's find out!

• "Free" Version Recycled Parts List:
- 35mm of Solid Copper Wire, thicker is better
- Coax Cable with SMA connector, can use an old antenna
- Metal Lid from a Pasta Sauce Can, or similar. Aluminum isn't recommended because it's very difficult to solder...
- Plastic/Wooden Tube to wrap copper around, about 15mm diameter.
º Or you can 3D print parts if you have a printer

• "Cheap" Version Parts List:
- 35mm of Solid Copper Wire, thicker is better
- RG405 Coax Cable with SMA connectors
º I ordered "Uxcell SMA Male to SMA Male RG405 Coax Cable" which was $10 and enough to make 4 antennas
- Copper Plate, or Blank Circuit Board
º I ordered "Copperlab 2-5/8 Inch Round Circle Disc Copper" f0r $15 and it's enough to make 12 antennas
- Plastic/Wooden Tube to wrap copper around, about 15mm diameter.
º Or you can 3D print parts if you have a

* Note: You can mix and match the above versions and substitute parts as needed. Something I mention in the video is these antennas don't have to be perfect to function very well.

• Basic Tools:
- Soldering Iron and Solder (with flux core ideally)
- Pair of pliers
- Ruler or Tape Measure
- Optional: 3D printer
