Antenna with longer cable (~140mm)
With that antenna mounted on your goggles you can fly freely behind you without worry that your head will block signal from TX :)
The Pagoda antenna is an omnidirectional circularly polarized antenna . This antenna was originally designed by Maarten Baert.
We done small modification of holes, to fit it better to RG402 cable and make solder points stronger. So we called it Pagoda 2.1
This is next generation circularly polarized antennas with great axial ratio (1.3), high efficiency which is 95%
Main advantages of Pagoda 2.1 antenna:
- Good omnidirectional radiation pattern.
- Good axial ratio.
- Reasonably small.
- Light weight
- Can be used as TX and RX antenna
Radiation pattern of Pagoda-2.1 antenna
Why choose Prodrone Pro Pagoda 2.1 ?
1. Quality soldering
2. Each antenna is checked on spectrum analyser.
Why checking antenna is so important ?
Manufacturing antennas for 5.8Ghz need very tight tolerances. Even small change of dimensions, geometry (even so small ad 0.1mm) will change their characteristics (resonation point - centre frequency).
Below is example. Antennas assembled in our assembly jig, which is more precise than original one designed by Maarten. You see how they differs their characteristics.
Buying our antennas you will know how use them properly - on which frequency they will have best performance.
