RCmall 5.8GHz Triple Feed Patch Antenna High Gain 9.4dBi Directional Circularly Polarized LHCP RHCP Antenna with 50ohm SMA Load Terminator for FPV Racing Drone Eachine EC800D

• The Triple Feed Patch antenna is a directional circularly polarized antenna..
• Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz..
• Good axial ratio, not just directly perpendicular to the patch but also off-center..

Foxeer Pagoda PRO 5.8G FPV Antenna SMA Pagoda Antenna RHCP 150mm Omnidirectional Antenna for Long Range FPV Racing Drone Quadcopeter TX/RX Black

• Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz.    Additionally, most array....
• Exceptionally good axial ratio, not just directly perpendicular to the patch but also off-center..
• High gain, though not as high as the theoretical gain of an array with 7 ?lements.    This is because maximizing the gain would result in high....
• Very low sidelobes, almost all energy is concentrated in the main lobe.    This increases the width of the main lobe, at the expense of some gain..
