Gain of Helical antenna is ~8dbi. Prodrone PRO 3.5 Turn Helical has very wide beam - 60 degrees. This is real beam width at highest gain. At shorter ranges beam width can archive 120 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 cheap chinese cables.
Semi-Rigid cable means that you can bend it and it will stay in that position. You can use this antennas on gogles.
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.
