Re: [Elecraft] Drone antenna launch Field portable! Changed topic.

[Terry Schieler]

I have been using a Blade CX2 RC helicopter to fly antenna wires up above tree 
tops for quite a few years now.  I had added an LED nav light kit to the CX2 
(red, green plus white landing light) and it runs off a simple on/off toggle on 
the transmitter.  I installed a small servo on the belly of the chopper that 
uses the servo arm to pull a piano-wire pin out of a U-shaped block of balsa 
wood.  The fish line antenna leader is hooked over the piano wire.  I installed 
a "Y" adapter to the navigation light circuit on the chopper and used it to 
fully activate the add-on (parallel) servo, which released the antenna lead-in 
line when it was properly hovering above the target tree.  So, when I flipped 
the nav light toggle to ON, the hook wire pulled back and released the fish 
line.  Took some experimenting with weights on the leader line to plow through 
some of the dense branches, but finally got it pretty consistent.  This started 
years before the word "drone" was common in R/C.  

Plain old radio-controlled helicopter (remember those?)

John,

Do use a separate receiver in order to activate the release or is there an 
extra slot on the drone receiver?

I'm assuming your using a bind - n - fly drone.  If it's home brew with your 
own receiver then it probably has a spare slot that you can program a switch to?

John,

Just re-read your email, does the Phantom have an extra receiver slot?

I have a Chroma that's a few years old which would have plenty of lift 
for a wire antenna, I need to check to see if it has an extra receiver slot.

I'll make a video of it in antenna-installation action once we dry 
out a bit more from Harvey. Cheap and works quite well, tree height 
is not an issue.

I've been doing this for 5 or 6 about  years now.  Even QST published the
picture of me doing it.  We also used it for Field day.

It is a great idea.  The release is just a $3 servo that pulls a pin to
drop the weight.  You just need to be high enough to have enough inertia to
pull the drop line through the tree leaves.

For quick and dirty QRP work, I still use a water bottle on a string.

Brilliant Idea.  What drone does he use as I would do the same in the future.  
How does the release work.  I would use with my KX2 while portable, out of the 
car.

My son, K4TOO uses his drone to place a messenger line where he wants it to 
pull antennas up through trees.  He has a remote release that makes it a very 
accurate operation.  He used it on Field Day this year and also to string 
hidden antennas up at his home QTH.
