Choose the ultra-lightweight FlyfishRC Osprey RHCP 5.8G antenna for clear FPV signal!
Get the perfect combination of light weight and high quality for your drone. The FlyfishRC Osprey RHCP 5.8G antenna is designed specifically for installation on compact FPV drones, where every gram counts. Its weight is only 2.1 grams, which does not disturb the alignment of the micro-copter. High radiation efficiency of 99% and low VSWR of 1.2 guarantee maximum power transmission on air. This is an ideal solution for building lightweight racing drones and mini-quicks.
-
Ultralight weight 2.1 grams. Does not weigh down the structure and is ideal for micro-drones.
-
High radiation efficiency 99%. Maximum transmission of video transmitter power on the air.
-
Low VSWR 1.2. Guarantees excellent matching with the transmitter and minimal losses.
-
High quality RG141 cable. Resilient and reliable coaxial cable for flexible installation.
-
Compact head with a diameter of 14.1 mm. Easily fits into the limited space of micro-frames.
Operating principle and design features
The FlyfishRC Osprey RHCP 5.8G antenna operates in the popular 5.8 GHz FPV band. Right hand circular polarization (RHCP) effectively suppresses multipath interference caused by signal reflections from the ground and obstacles. The high radiation efficiency of 99% means that almost all of the video transmitter's energy is converted into radio waves rather than being dissipated as heat.
A low VSWR (standing wave ratio) of 1.2 ensures perfect matching with the VTX output stage. The compact 14.1mm antenna head and flexible RG141 coaxial cable make it easy to fit the antenna into the tightest bays of micro-drones, while the ipex/UFL connector provides a reliable connection to the video transmitter board.
