The arborist throw line is an invaluable field radio kit tool

Two days ago, I activated Parc national des Grands-Jardins (VE-0499)–a stunning national park here in the Charlevoix region of Québec, Canada.

As soon as we drove up to the activation site I had researched in advance, I surveyed the picnic area and mentally noted the best spot to deploy an end-fed half-wave using my trusty arborist throw line.

With the throw line’s assistance, I had an antenna deployed within a couple of minutes max.

It hit me then just how invaluable a tool the arborist throw line has become for the types of park and summit activations I do.

Pre-Throw Line Activations

During NPOTA (National Parks On The Air) in 2016, I wasn’t aware of arborist throw lines and had been using some high test monofilament fishing line attached to a weight.

The fishing line was strong enough to support my QRP antennas and I could typically reuse the same length of line for 2-3 activations. Eventually, the line stretches and weakens thus it must be cut off and discarded.

Never again

I’m a big Leave No Trace kind of guy, so am embarrassed to admit that during one activation, my fishing line snagged high up in a tree and left a bundle of broken monofilament in a spot where I could not retrieve it. This was deep in a forest and although I doubt anyone will ever see it, I know it’s there. It bugs me to this day and if I ever sort out a way to remove it, I certainly will.

This occurrence was one of the catalysts for purchasing my first arborist throw line kit.

That throw line kit absolutely revolutionized my antenna deployments by:

  • increasing the speed deployment,
  • increasing accuracy,
  • allowing me to re-use the same line hundreds of times,
  • and being orders of magnitude more reliable and stronger than fishing line.

It changed everything and I’ve never looked back.

Since that first throw line kit (which I’ve lent to a newly-minted active ham), I’ve built four more throw line kits.

Compact Weaver Throw Bag

In early 2021, I purchased a second throw line and 12oz weight (identical to my first) for backpacking along with this compact Weaver Leather throw line storage bag (affiliate links).

I was searching for a more SOTA-friendly/backpack-able solution than the arborist throw line cube.

I was very skeptical about how easily this bag would work in the field. One of the reasons my throw line storage cube works so well is because the opening is large allowing the line to deploy without tangling. Packing up is fast because the line can be flaked back into the cube in a matter of seconds. Continue reading The arborist throw line is an invaluable field radio kit tool

How to pack a compact Arborist Throw Line Storage Bag

Since last year, I’ve become a bit of an arborist throw line evangelist.  Arborist throw lines have made my wire antenna deployments so quick and easy compared with using monofilament fishing line or more complicated systems.

Since purchasing this arborist throw line last year, I’ve never looked back. The throw line never gets caught in tree branches, it’s reusable hundreds of times, and with it I can easily snag branches 50’+ above the ground to hang my wire antennas.

When I purchased my first arborist throw line, I also purchased this folding throw line packing cube:

It has a huge opening, is stable on the ground, and makes for an incredibly quick deployment and pack-up.

While the cube folds into a compact triangle, it’s a little too bulky for backpacks I use during SOTA and other trailside activations.

A smaller throw line storage bag

A few months ago, I purchased a second throw line for backpacking and this compact Weaver Leather throw line storage bag (note: Amazon affiliate link).

If I’m being honest, I was very skeptical about how easily this bag would work in the field. One of the reasons my throw line storage cube works so well is the opening is large allowing the line to deploy without tangling. Packing up is so fast because the line can be flaked back into the cube in a matter of seconds.

Before purchasing, I was afraid the compact throw line bag might get tangled when being stored in such a small stuff sack. I was really concerned packing the line in the storage bag might take too much time.

I purchased the the throw line bag and a new throw line from Weaver.

At home, I did a full break-in of the new throw line (attaching it to a tree, stretching it to full length, then pulling it for enough tension that some of the bend “memory” is removed). Then I attempted to simply stuff the line in my throw bag–it took ages, because the whole idea of a throw line is that it doesn’t easily tangle. The line wanted to “spring” from the bag as I tried stuffing it in.

A much better way: The “Figure 8” stuffing method

After a field activation this spring, I received a game-changing tip from one of my subscribers and I hope they step up to take credit! (Update: it was NW3S!–thank you!).

When stuffing the line back in the bag, wind it on your hand using the figure 8 method. I wind almost all of my lighter-weight cables and antenna wires in a figure 8 so that they deploy without getting tangled. I’ve been doing this for years and it works brilliantly.

I’d never thought about using this method on the arborist throw line. I was amazed with how effectively it worked.

Video demo

I made a short video (thank you for requesting this, Scott!) to better demonstrate how I pack my throw line storage bag now:

This method works amazingly well and I can usually pack the entire line within one or two minutes.

Again, I’m incredibly grateful to the subscriber who first suggested this method!
