Basics for 2.4g dipole antenna construction. I found it roughly doubles the number of Wifi networs I detect with max signal strength and it significantly increases camera frame rate.
**pic 1: **Parts needed. flush cutters, lighter, heatshrink tubing, solid core wire (guage doesnt matter much but should be stiff), old sma antenna from a laptop or the oem CC antenna, solder and soldering iron
pic 2: Desolder the SMA connector from the stock film antenna, scrape or burn off enamel on the copper wire and tin with solder
pic3: solder inner line of the SMA coax cable to one of the copper wires.
pic4: heatsjrink around soldered joint to insulate
pic5: solder second wire to outside of coax sma connector
pic6: heatshrink outside
pic7: bend poles apart tightly with pliers or similar 90 degrees
pic8: measure 30.5mm (quarter wave length) from the bend point and cut each side to length.
pic9: completed antenna
