PRO Helical antenna 12 turn 5.8 GHz 14dbi v2
Gain of Helical antenna is ~14dBi and this is real gain.
Great antenna for very long FPV.
Prodrone PRO 12 Turn Helical has beam ~30 degrees. This is real beam width at highest gain.
At shorter range beam width can archive over 50-60 degrees.
All PRO Helical antenna series have a semi-rigid cable.
We are using high quality RG402 cables (mainly made by Belden or Suhner). We are not using cheapest cables.
Semi-Rigid cable means that you can bend it and it will stay in that position. You can use this antennas on goggles.
This means that antenna can be pointed in any direction and there is no need for using any adapters.
Cables that we are using have very low attenuation, so you'll be able to fly even further.
Each antenna that we made is hand assembled, tuned and checked on VNA.
Every antenna has small label with tuned frequency (frequency range on which best performes).
Every order with more than one antenna (5.8Ghz) is processed individually. All antennas in that order will be tuned for same frequency range.
