This set includes:
- tuned 3.5 turn helical RX antenna - RG402 semi-rigid cable
- 2 pieces of PRO Pagoda 2.1 antenna with cases
- 1 piece spare case to Pagoda-2.1 antenna
Prodrone Pro 3.5 Turn helical antenna
Gain of Helical antenna is ~8dBi and this is real gain.
Prodrone PRO 3.5 Turn Helical has very wide beam - 60 degrees. This is real beam width at highest gain.
At shorter ranges beam width can archive 120 degrees.
All PRO Helical antenna series have a semi-rigid cable. We are using high quality RG402 cables (mainly made by Belden or Suhner). We are not using cheap Chinese cables.
Semi-Rigid cable means that you can bend it and it will stay in that position. You can use this antennas on gogles.
This means that antenna can be pointed in any direction and there is no need for using any adapters.
Cables that we are using have very low attenuation, so you'll be able to fly even further.

Prodrone Pro Pagoda antenna
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
Why to choose Prodrone Antennas ?
- Quality materials
- Quality soldering
- Each antenna is checked on spectrum analyzer.
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 theier characteristics (resonation point - center frequency).
Below is example. Pagoda Antennas assembled in our assembly jigs and specially developed tools, 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.
