Description
Enjoy a more comfortable and versatile FPV experience with our Pagoda 2.1 antenna featuring a longer cable (~140mm). Say goodbye to video dropouts caused by your head blocking the signal from the transmitter and fly freely behind you.
The Pagoda antenna is a circularly polarized omnidirectional antenna originally designed by Maarten Baert. Our Pagoda 2.1 antenna features slight modifications to the holes to fit better with RG402 cable and provide stronger solder points.
This next-generation antenna boasts an impressive axial ratio of 1.3 and a high efficiency of 95%, making it a top-performing circularly polarized antenna.
The Pagoda 2.1 antenna offers several benefits, including a good omnidirectional radiation pattern, a good axial ratio, and its reasonably small and durable design. It's also lightweight and can be used as both a transmitting and receiving antenna.
You can trust the quality of our antennas because each one undergoes multiple tests and checks on a spectrum analyzer during production. Additionally, all antennas in your order are carefully tuned to work together within the same frequency range.
Why choose Prodrone Pro Pagoda 2.1?
- Quality soldering
- Each antenna is checked on a spectrum analyzer.
Checking the antenna's characteristics is crucial because manufacturing antennas for 5.8GHz requires tight tolerances. Even a tiny change in dimensions or geometry (as small as 0.1mm) can affect the antenna's resonance point, or center frequency. In the chart below, you can see how different antennas assembled in our precision assembly jig (more precise than the original one designed by Maarten) can exhibit different characteristics.
With a working frequency of 5.8GHz, a gain of 1.1dBi, and a vSWR lower than 1.3, our Pagoda 2.1 antenna is an excellent choice for an omnidirectional antenna. It has a maximum power input of 50W and is available with either an SMA or RP-SMA connector. Plus, you can choose between right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP) to suit your needs.
Radiation pattern of Pagoda-2.1 antenna
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.
