Using a quadcopter to hang an antenna

A few weeks ago several folks here were discussing the hanging of an
antenna line with a quadcopter and were wondering what's available to allow
a quad to drop a line over a tall tree or other structure.

https://ae5x.blogspot.com/2017/10/using-quadcopter-to-hang-antenna-line.html

I just finished putting my 80m dipole up at the 90-foot level and took a
few photos of what I use to do it. The key to the whole thing is the
payload release device since a quad cannot descend with the line still
attached.

Re: Using a quadcopter to hang an antenna

There's a good article in Nov QST on the very subject.

I use my 7 lb payload hex copter with a payload release and a round one
pound fishing weight......great fun.

In reply to this post by John Harper

Oh, it can descend with the line attached, just not gracefully.
Reminds me of when a Marine Corps Major asked if he could test fire a
Stinger missile over the Potomac River, to which my boss replied.
Maybe....once.

In reply to this post by John Harper

Interesting.
I have a 5 servo 8ft Helicopter, been flying them for years, but I've always used an old 12ft fishing beach caster with 30lb line and 5oz fishing weight..
I can zip it over a 100ft tree, tie on a light line, reel the fishing line back in then you can haul up the dipole end.
Takes a few minutes to set a full 160m dipole between 2 suitable trees for Field day.
Look out for one at your next boot / flea market sale!!

Re: Using a quadcopter to hang an antenna

In reply to this post by John Harper

I checked out a few youtube videos, especially "drone fishing" ones, and
a less expensive drone with a kinda T-shaped wire (a very flat "hook"
parallel to the ground) could work very nicely.

The release mechanism is cool, and certainly the "GPS Hold" function is
neat, but they add cost.

The trees I want to use won't support a climber very high.

Re: Using a quadcopter to hang an antenna

In reply to this post by John Harper

Hi all

It doesn't have to cost $800.

A couple of years ago I bought a Chinese quadcopter, complete with video
camera, 2GB micro-SD card, card-reader, spare propellers, 2.4GHz remote
controller, and including shipping - all for $68. But I think the price has
come down now. The total "diameter" of the thing is only 35cm or so. The
quadcopter at time of purchase, had various optional attachments you could
choose, not just the video camera. There were things that fired little
darts and stuff like that. So basically there is a spare channel which is
operated by a button on the remote control, no need for an additional radio
transmitter. Of course it doesn't have things like GPS hovering and you
don't want to fly it in any kind of wind, any at all.

I have a plan to hoist a wire over my next door neighbour's tree. My
previous attempt to THROW it over the tree by standing on my rooftop did
manage to land in the middle of the tree but was hardly OVER it, and in
hindsight trying to throw it while balancing on the roof didn't seem like
it would increase my life expectancy any. A storm took down the wire. And
the quadcopter seems a better solution.

A few weeks back, I did go out one morning early, before the sea breeze
started up. I was all ready to give it a go, but I discovered that the
fishing line I have is a little too short. Then I remembered how one
earlier attempt at throwing fishing line into the tree from the roof had
resulted in a lot of tangled up line which had to be thrown away. Now I
have bought some more line and yet to get around to a retry.

Even that tiny cheap quadcopter had plenty of power to lift the fishing
line to around twice the tree height (I guess about 60 feet), and it had
still enough power to lift the plastic reel that the end of the line was
tired to.

Re: Using a quadcopter to hang an antenna

In reply to this post by Ken Chandler

My problem when I miss is getting the weight to go back up without tangling or coming right back at me. I made a Pipe cannon using bicycle pump compressed air with a sprinkler valve opening with two 9v batts. The same issue watch out for the weight. I use a pair of caps on smaller pipe, but that can still be an issue. Now to find a use quad copter.

Re: Using a quadcopter to hang an antenna

I did this years ago and even had it published in QST. It was at least 4-5
years ago.

It was a basic Quad copter, a simple Wii flight controller and a dedicated
servo that pulled a pin out of a block to release the weight.

It worked very well. I should get the pick back on my QRZ page.

I bet I had less than $100 invested.

Re: Using a quadcopter to hang an antenna

In reply to this post by John Harper

GA,

I have used CSV19 from:

http://www.antennalaunchers.com/antlaunching.html

Best way to use it is: one club-member has it and use it,

but service is available for all members.

This way the antenna will be launched OVER THE TREE.

All styles have been tried: army launch, sling-shots, shotgus etc.

This has been absolutely number one up to now.

Hydrocopter is promising if used properly.

Re: Using a quadcopter to hang an antenna

I built my own and chose the spiderwire fishing line. Works great. The
fishing line is hard as heck to see but super strong. Goes over 100ft
trees with no effort.

Re: Using a quadcopter to hang an antenna

I don't have photos but my launcher is similar but the sprinkler valve is on the end and the "shooting" tube is on the end... not so compact. The overall length is 40" + and it is easy to aim. The issue is how much air to use. My air cavity is much shorter and I can do 70Lbs. with a bicycle pump. I can do 90+ lbs. and agree with the spider wire.
