DIY Special – High Gain Antenna Kit 2.4GHZ and 5.8GHz – for Q500 /4K, ST-10 /+

  • This Antenna kit contains all you need to get 4000FT  on your Q500 or other model aircraft using directional 2.4 and 5.8 GHz antennas.
  • Circular polarization improves signal reception and reduces dropouts.
  • The antenna radiates a beam which concentrates the transmitter power into a cone directed at the aircraft.

  • Here’s a bargain no builder can pass up! These high quality, high gain antennas were made to work with the Yuneec Q500/4K drones and sold for $129, and indeed we still sell them for that purpose, as the Q500 is a classic and good looking aircraft, so if you have one you should have this setup as well.
  • Anyway, the kit is made up of two antennas, one 2.4GHz and one 5.8GHz, very high gain and directional.
  • This means better range in free space than the usual panel type antennas.
  • The line of sight range is about 4000FT.
  • They are very rugged and precision made, and there is almost no limit to their uses in 2.4 and 5.8 RC modeling.

The Physical details:


  • One each 2.4 and 5.8 high gain helical antennas with ground planes (reflectors) that double the gain.
  • Both mounted on a rugged thermoplastic plate.
    • The plastic plate may be cut to remove the antennas or mount them in a different way.
  • Each antenna has a 6.625″ length of RG-58/U and Gold plated SMA connector.
  • You also get two SMA-to-U.FL cables.
    • The U.FL connectors are what plug into the actual radios inside the drone remote controls, and the SMA jacks connect to the SMAs on the antenna cables.
    • The U.FL cables are 4.5″ and 9″ long, and the connectors are Gold plated as well.
  • A couple of wire ties are also included – are part of the kit.

All the TECH details are below:

This kit is designed for all Yuneec quadcopters using the ST-10 and ST-10+ controller for ranges of 4,000 ft unboosted and 8,000-12,000ft boosted (with optional 1 5.8ghz amplifier and 1 2.4ghz amplifier, not included at this price).
What is included in this kit:

1 u.fl to rp-sma female cable (rg-178 coax) 9cm long (for 2.4ghz rc control antenna)

1 u.fl to rp-sma female cable (rg-178) 20 cm long for 5.8GHz wi-fi antenna (video)

1  2.4GHz Half Sphere helix 9dBi LHCP (to extend rc range)

1 5.8GHz  LHCP 4.25 turns 5.8ghz helix antenna (to extend wi-fi/video range)
