ORT 6 Turn Helical Antenna “Long Range Master” (10dBi Gain)
The helical design has a 180ohm impedance which is not matched with ORT's FPV system with 50ohm impedance. Hence so-called helical tuning is the most important part to ensure the antenna match with ORT's FPV system to provide you with the most efficient directional antenna. A perfect balance between beamwidth vs range.
ORT designed the Helical 6 turn to get a perfect balance between performances of beam width (signal coverage) versus range. Covering 100~120 degree of beam width with an effective range of 10~20km and beyond with 600mW video transmitter hence the called of Long Range Master given. ORT recommend using this with our ORT cocktail Omni antenna to get the best performance.
