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.

Hand Tuned, 110~120 degree coverage with 15~20km clear ranges and beyond on 600mW Video Transmitter (depends on flying area noise, receiver sensitivity, and FPV setup)

Enameled Wire(anti-rust)

Original Low loss RG402 cable

High-quality acrylic, providing a premium look
