Egads- where I live the only “paperwork” for having a tree removed is a stack of Benjamins.
On a serious note, I have been planning some tree work anyway and ADS-B is the least important reason for that. Some are dangerously close to the house and a danger in high winds.
I am sorry for you. Run for council and change that stupid waste of time and public resources.
The antenna is still holding.

PS: Funny, I am out of country now, typing on my Kindle (annoying).
I had to google what a stack of Benjamins is.
I live in a tree lined heritage listed suburb where the rules are very well defined and rigorously enforced. The exceptions seem to be related to graft and/or corruption but the laws of slander prevent raising such a concern.

Yes, sorry to use US usage on that one. But yes, there are areas here where things are restricted, particularly in some cities and designated historic neighborhoods and so on. I happen to not live in a restricted area other than requiring building codes for construction, permits for certain types of repairs and such. Taking trees down carefully ( eg without dropping them through the roof of my home) is expensive.
This is LNA with two SPF5189?
Probably, I forgot where I had posted about that. The chips are partially erased, but I could guess what they are.
I have added the 5V stabilizer IC.
Young minds. Must be nice 
I have added a post on that thread about my actual chip (the first one, that I could decipher).
Well after 2 years, the nylon paracord rubbed and rubbed against the tree and eventually broke off. The antenna came full speed down, but no damage was done.
Back to work to trow the line over a branch. I guess I am not vet good at this, after numerous tries with different devices. Tried a small bow (arrows got stuck up there), a bottle of water swung on the rope (I kept missing the correct direction) and my old slingshot (rubber got old and was shooting sideways).
I managed to go half way up there and I declared “job done”. Oh, well, still higher than on the roof of the house.
It’s not perfectly straight, because the coax cable pulls it sideways. Maybe I’ll release a little bit the tension later, just didn’t want the cable to droop too much…
With a potential skyhook that high that’s only going to get higher, I think I’d be tempted to pay a professional to do something for me although I don’t know how high someone could practically climb that.
This is the most extreme antenna launcher and may, just may be excessive to your needs.
Search for Ham antenna launcher on youtube for more sedate versions.
(Note, this would probably be illegal in Victoria AU)

Definitely illegal in the UK without a firearms certificate (which you almost certainly won’t get for something like this). If it’s air powered with a muzzle energy over 12 ft lbs and a barrel over 16 inches, it’s classed as a firearm.
A longbow with over 100 ft lbs of energy is completely legal though…
I’m surprised at how low the pressure is there - I charge my revolver air cartridges up to anywhere between 250 and 300 bar!
The volume in a revolver cartridge is much smaller though, so you need a much higher pressure to store a similar amount of energy.
A tennis ball only has to be going just over 50mph to have more energy than is the limit for air weapons in the UK.
Oh yes, I appreciate that. I’m just surprised how little is required.
In my city limits you can’t discharge a fire weapon/device or a shoot a bow and arrow that has more that 20 lbs pull force. I have a toy compound bow (with some 20 lbs), but the arrows are too light, they got stuck in the branches…
That compressed air canon makes noise like a gun, so my neighbors might call the cops 
Granted I did a mission similar with 3/4" bolt nut tied to fishing line, fired it over the branch 25ft up with wrist slingshot - to pull up tree swing ropes 3/4" in dia, and it lasted a good 10-15 years before the treated rope finally gave out.
But for your mission which I see was a few years ago -
I’d call in the tree trimmer that can go up on very high bucket lift a good 50- 60 ft up, and he’ll need to do some trimming regardless, now have him mount the 20ft steel
fencing pipe used at top of commercial chainlink fencing,
as one member mentioned earlier.
These new trimmer lifts are very cool, self propelled all wheel steer and drive with huge out riggers for stable out reach.
Hope it all went well.
Cheers
Yeah, that would be nice, but, at the rate of $290/day for the 35’ one or $390 for the 50’ one, is a little too steep for just this hobby.
