Cool Making antenna – update

So today I tried the new antenna, gosh it is so convenient to use, very small footprint and very light.

Now to the important things. I managed slightly over 3km (remember we have CE over here in the UK) which is my all-time record!

Flight Overview

I could have gone farther but as I predicted the battery let me down. Actually, the winds were also very strong.

I was below the return to home mark few times during the flight, making the flight ever so interesting.

So the final judgement on the antenna: 4/5

Here is the link I bought it from: https://www.ebay.co.uk/itm/16DBI-2-4-5-8GHz-Extended-Range-Antenna-Wifi-Signal-Booster-For-DJI-Series-Drone/162612783776?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D2%26asc%3D49138%26meid%3Db78f97acb53e4ff78db4ba1ce32b3043%26pid%3D100005%26rk%3D3%26rkt%3D12%26sd%3D232604156093%26itm%3D162612783776&_trksid=p2047675.c100005.m1851

Hope it helps!

Don’t buy these Chinese patch antennas!

My constant pursuit of finding the best antenna for the drone got me to buy a bunch of these antennas. Initially I did not understand why the drone would lose its signal even before 300 metres.

Well I have decided to disassemble the antenna and the reason why is staring you in the face. Its made from tin foil and a bunch of wires

Bear in mind that I paid around £15 for each. If I remember correctly the antenna is rated as 8 dbi for 2.4ghz and 11 for 5.4ghz.

Stay clear of this junk

“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.
