Actually, the equipment can be modified to accept an omni-directional aerial.
The small issues about the ANO regarding endangering an aircraft in flight - well, the device which uses a net is also technically in contravention.
In the wider world (ie Turkey and more lawless and corrupt countries like the US) this is not an issue. If government agencies are interested, I'm sure that the equipment can be modified to fit the current regulations, or that ammendments can be made. There is already a device manufactured in the US which is effective to 300 metres.
Once the units are out of my hands I don't care what happens to them. I live in Taiwan, and the sale is through third parties anyway. No prison food for me. It's not illegal to manufacture or sell them here.
To answer your question about jamming GPS at ground level - if you are directly beneath the drone, then it is not effective. However, from an angle, it works like a dream.
In any case, the whole design is mainly a proof of concept showing that the technology is there and can be utilized if required.
I'm a pilot turned engineer and my company specializes in developing and maintaining aircraft systems, railway asset protection, calibration equipment and signalling systems.
This jamming device is just a side project, the development of which will probably lead to other things, although to date, 68 units have already been sold.

I think drone control is frequency hopping 2.4ghz so any jammer would also be jamming wifi, cordless phones and other devices also legally able to use 2.4ghz. And if you jam GPS frequencies again plenty of other legitimate users with GPS in their phones and cars would be upset! Even a basic drone if jammed should default to either fly Return to Home or fly autonomously via preset waypoints. Of course if GPS was also jammed it would then fly I would guess on a default heading such as North or could just be random pattern. If you jammed it and it then crashed and hit someone or a plane then who would be responsible? Hope you have good insurance cover!
But it's a really nice sexy gun-shaped thing with a designer matt-black finish and some seriously cool-looking antenna-shaped pods and a smart black backpack - presumably the backpack can also take it's designers schoolbooks and sandwiches, so it's good VFM.
Still no patent number then. Perhaps the backpack has pockets for the puppet to keep his socks in...

The 'i' newspaper in UK has a report headlined ‘Concerning’ increase in near-misses between aircraft and drones, with much of it sourced from Freedom of Information requests.
There's also a list of 16 incidents since 2014 where there was a "serious risk of collision".

So this was last week when the HoftS arrived in Southampton:
The DJI P4 took off from the old wharf south of Ocean Village Marina under FPV which is exactly 3 nm from the runway threshold of runway 02 at EGHI on the extended centreline.
So he flew for over a mile under the hood which is BLOS (beyond line of sight) = illegal as no observer and looks to be well over 400 AGL in some of the frames judging by height of cruise vessel which is 210 ft high
If there is any Flybe jockeys seeing this they will not be very impressed as this is EXACTLY in the final descent profile which starts at 5.6D from the airfield.

Eagles, again
The Dutch are exploring the use of trained eagles to snatch drones out of the sky.

This would be highly illegal under US Federal Law and FCC regulation and possibly others besides, and it should be everywhere. Jamming of radio signals is not something that should ever be done in peacetime or by civilians, cut and dry.

British drone-freezing ray gets US airports trial - BBC News
A UK-developed system capable of jamming signals to small drones is to be trialled by the US aviation authority.
Seems to me though that it depends what the drone is programmed to do when it loses control signal, could be quite unpredictable. If its 'hover'it doesnt help much. If 'land' possibly. If 'RTB' then bonus, it goes back to the perp.
And to answer chromonkey - The key point is directional. Firing a tight beam up into the sky, would be very unlikely to affect anyone. And exceptions can and are made to FCC and other regulations for specific cases. I suggest that downing a dangerous drone, in the hands of federal authorities (police, security) would get passed.

Of course you'd better hope that this drone doesn't have antenna-diversity, and that the jammer's antennas are made of that special unobtainium alloy that eliminated side-lobes, or that the operator has the courtesy to only operate it in places where the drone death-ray can get a clean shot at it without impinging on any aircraft, offices, hospitals, schools, homes etc who might suffer problems from being subjected to illegal high-powered jamming signals in the 2.4GHz band.
Well, my company has just patented a directional jamming device which jams GPS, video link and control input

The DJI drones have geo fencing in the software. If won't fly if its in restricted airspace or it may limit the altitude to stay out of the lower tiers if its above you.
DJI have this locked down pretty well so can't see an issue in that video for that reason.

First autonomour passenger-carrying drone begins testing
https://www.theguardian.com/technolo...g-ehang-nevada
"Tom Wilczek, Goed’s aerospace and defence specialist said: “The State of Nevada, through NIAS, will help guide Ehang through the Federal Aviation Authority (FAA) regulatory process with the ultimate goal of achieving safe flight.”"
A new beginning?
