Connector      : SMA 


MADE IN INDONESIAspecial 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 owndesign, 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 antennaWe 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 antennawith 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.

Saran penggunaan :

1. Perbedaan helical dengan patch antenna, Helical menggunakan element khusus dan dituning dengan alat profesional khusus di setiap antennanya untuk memastikan mendapatkan “match” atau efisiensi(axial ratio) tinggi sehingga memiliki cakupan sinyal yang lebar dan penetrasi yang baik dibanding Patch yang hanya menggunakan PCB.

2.  Helical 5 turn sangat kami sarankan dipasang pada Diversity monitor maupun receiver seperti TrueD, Realacc, Holybro, Eachine dan dipasangkan dengan ORT Cocktail dan Goggles edt sehingga diversity bekerja dengan maksimal untuk memilih sinyal terbaik dari 2 antenna yang berbeda.

3. Helical 3 turn sangat baik digunakan untuk quad race dalam penetrasi pepohonan maupun medium/long range pesawat. Helical 3 turn memiliki kabel pendek dan lebih ringan dibanding helical 5 turn untuk digunakan di goggles.
