Description

MADE IN INDONESIA, special tuned for each Antenna. Helical Antenna has 2 modes, which called ‘Normal Mode’ (linearly polarized) & ‘Axial Mode’ (circularly polarized). The Axial Mode is the one we are using normally for FPV since it has benefit of circularly polarized radiation. Based on its own design, Helical has 180ohm impedance which is not matched with our FPV system with 50ohm impedance. Hence so called helical antenna tuning is the most important part to ensure the antenna matched with our FPV system and providing you most efficient antenna. We had tested 3 turn helical with our Cocktail omni antenna to get stable signal as further as 8-11km with wide signal coverage, perfect antenna for balance of wide signal coverage & range.

ORT 3 Turn Helical is designed to match with your circular transmitter antenna (matched best with our ORT Cocktail). This antenna has best axial ratio compare to el cheapo circular patch antenna with printed pcb out there. If you handle ‘hard’’ RF environment such as surrounding with building & tress or need better penetration thru obstacles or even just to matched with your diversity receiver and also light enough to mounted in your goggles this is your perfect matched. Strap one and get clearest video even on hardest RF environments.
