I don't think that's where Larry and Bill (W3WH) got their launcher, but what they have is very similar. And yes, it is pressurized with a bicycle pump; I've used it a few times.
Slick. And if you're planning to put up a lot of wires in trees, very effective. Sure beats tying a string to a wrench, trying to toss the wrench over a tree limb, and then spending 2 hours trying to find the wrench...

Yes, that's the same video I posted here a while back. Maybe I should but a HamIsland logo on mine. ;)

Oh? Interesting.
The link I posted was to a video courtesy of Larry K3VX, filmed by his wife Tippi WA3JPP(SK). I think Larry & Bill had another one online, but I couldn't find it on short notice.

Here's a link that'll show you how to homebrew one.
The one I bought used that same slingshot, but the fishing reel is attached to the slingshot with hose clamps on one of those side rods. It's down in my car now, but I'll be able to take a pic to post tomorrow.

If it's a war on drugs, then free the POW's.
One tip I read somewhere, probably the ARRL Antenna book or a Handbook, was to NOT shoot for a particular branch in the tree. Shoot the weight over the entire tree. The attached line will find the branch it wants to be on by itself.
Works well, when it can be used. Can't always get where that's possible on some trees.
About pneumatic launchers....look like a lot of fun, but is it really cost-effective over a slingshot setup?

[AM'er OF mode on]Not at present, but that's only because I don't have the proper gear for it (I miss my HT-37 at times like this...)
HT-37? Proper AM rig? Ahem....a "proper" AM rig has lotsa heavy metal in it -- mod transformers are a requirement! And low-end audio frequencies are too. Hi end is up to the individual station and how much BW the op is willing to use.

Yes, shoot it over the whole tree, and it's best to NOT run wire into/through the tree. Use rope to support the wire in the air, but out of the tree. And it's easy to copy the design on the link I gave. The design on the video link is similar to the kit I bought...
But yea, to argue the semantics (if we must) theirs is a little different than mine.

This is just a test. Speaking of antennas, this is my home brew link coupled antenna tooner..........

This is a link to pics of the innards of my AM transmitter.........a 4-1000 modulated by a pair of 833's....

Looks line one damn FB tuner. I'm a total aficionado of that kind of tuner construction (been known as the Tuner of Death), but have considered making one that's switched and enclosed. Gave up on that project when I got a Matchbox.
That pic shows just how simple a really good tuner is - takes little time to construct. Finding the parts can be tricky, but they're out there & available and not all that expensive.
Super!
FWIW -- I didn't have a proper "link coupled coil." No problem. The Handbook circuit made the coil out of one piece of standard coil stock. Two cuts are made, making three coils. Two equal ones on the outside - that's the output side, and the inside coil (smaller) is the link. Worked fine.
