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

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'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. Mike va3mw On Wed, Aug 30, 2017 at 8:20 PM, Bill Johnson wrote: > Brilliant Idea.

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. 73, Bill K9YEQ -Original Message- From: Dave Sublette [mailto:k...@arrl.net] Sent: Wednesday, August 30, 2017 6:59 PM To: Elecraft Reflector Cc: Bill Johnson Subject: Re: [Elecraft] KX2 owner discovers Heaven/P My son, K4TOO uses his drone to place a messenger line where he wants it to pull antennas up through trees.
