NEWS: Emax Pagoda-2 antenna

[Drone News]

As you may know, Pagoda’s antenna is novel type of circular antenna as can by cloverleaf and mushroom models. A new model from Emax is introduced: https://www.banggood.com/2-PCS-Emax-Pagoda-2-5_8G-50mm80mm-5cm8cm-LHCPRHCP-WhiteRed-FPV-Antenna-SMA-p-1152417.html

The main advantage of pagoda antenna is the rejection rate of the dual circular polarization waves. For example, if you have a RHCP pagoda antenna, LHCP signals will be deeply rejected and won’t interfere too much with RHCP waveforms and by consequence will decrease statics and increase the FPV range. You have to know for example that first of all a RHCP cleaverleaf antenna emits part of its power with LHCP and second point each diffraction point can potentially transform a RHCP wave into a LHCP one. On the reception antenna, at the end a part of the RHCP signal is then corrupted by a non-negligeable LCHP signal level. Ideally if at emmission, the LHCP can be decreased as maximum and at reception LHCP can be rejected…. the general RX sensitivity will be even better. This Emax bundle offers 2 antennaes with either 5cm or 8cm of length and the two choices of polarization.
