3turn Death Ray Helical Antenna.
This is the 3turn death helical antenna by Hendrik.
Specifically designed and built for the DJI HD FPV goggles.
Designed with low dBm loss, high gain and wide beam width in focus.
Keeping the dBm loss at a minimum by eliminating unnecessary connectors and sharp bends in the coaxial cable and increasing the beam width with the angled design.
The beams of the antenna overlap in the -3dBm zone which means the signal is very strong even in between the beams.
The antennas are 3D printed and handmade in Sweden. The antenna’s front and back supports are made from solid PETG. The reflectors are made from double sided copper/fiberglass PCB board. The coils are made from 1.4mm solid copper wire.
The coaxial cable is semi rigid RG402 and the connectors are high quality gold plated RP-SMA 90degree connectors.
The antennas are LHCP to match the polarization of the DJI Air Unit antenna..
|Total beam width||174 degrees|
|3 dBm beam width||-100 degrees|
|Tower offset angle||40 degrees|
