“Cool Making” Helical Antenna – 16 Dbi – Updated!

Today I have received an antenna under the brand name – “Cool Making”. I have purchased it from eBay a few weeks ago for £38, which is nothing compared to Fpvlr which sell a comparative antenna for £117 with lower dbi rating (which in reality means nothing) .

On eBay, they sell several variants of the antenna in either black or white and for DJI Mavic, Phantom 3 Adv/Pro, Inspire 1 and for Phantom 4 Pro.

The build quality looks quite good and according to my measurements, it should fit perfectly to my modified GL300A controller.

They promise the range of over 7km range unboosted. My previous best distance was 2.6 km using Alpha directional antennas (could have gone more but I chickened out having never flown that far. PS: I’m flying in the UK so the CE limitations apply in my case)

If you’re wondering where the reflector is, it’s embedded within plastic casing and is made from aluminium. Unfortunately I couldn’t open the antenna without breaking it to take the pictures of the internals.

Overall the build quality is surprisingly good for the Chinese clone of the more expensive options.

I will wake up very early tomorrow to perform the same test I did for alpha patch antennas. I will fly the same route and altitude as I did before. If I get close to 4km I will be very happy and I will stop searching for new antennas. I never fly that far, always within VLOS, but I hope that the video quality will improve

On paper, these offer 16 Dbi so they should take my drone much farther and I hope the battery will be the limiting factor.
