    • 15 meter adapter*
    • 12 meter adapter*

Loose Items in L.L.Bean pack

Note: The 20 meter EFHW wire has a connector in the middle of the length.  By unplugging this connector and removing the half of the wire at the “far” end (i.e., away from the transformer and feedpoint) and replacing it with one of these adapters, the wire is then reconfigured to be an EFHW for 17, 15, or 12 meters.

Other Items as Appropriate (most items not for hikes of any great distance)


My experience from years of traveling for both pleasure and business has shown that I always overpack and take too much “stuff”, and POTA is no exception.  However, I have made an attempt to modularize my POTA gear so that I can lighten my load depending on what type of activation I have planned and how far I will be going from my parking spot.  If you will spend some time scrolling through my blog, you’ll find examples of most of the following:

If I’m going to a location where I’m planning on operating at or not too far from my truck, I’ll take everything on this list to give me maximum flexibility as to how I set up.  Probably the most extreme setup involves erecting my 12 meter Spiderbeam mast on my heavy duty towing-style bicycle rack and deploying a wire antenna as an end-fed vertical or as a sloper.

At the opposite end of the spectrum, if I’m going to be doing a pedestrian mobile (/PM) activation then all I need is my KX2 bag, my Maxpedition Gear Cocoon Pouch, probably my Sony ICD-UX570 Digital Voice Recorder (unless I can manage to log on paper somehow), and (optional) my battery bag with shoulder strap.

If I know that I’ll be doing a wire antenna activation using a tree for support then I can wear my L.L.Bean day pack, but omit the Maxpedition Beefy Pocket Organizer and the Maxpedition Gear Cocoon Pouch.  In that case I’ll likely wear my battery bag with shoulder strap.  I may put the KX2 bag in the pack or carry it by its handle.

And, if I know that I’m going to be doing an AX1/AXE1/AX2 picnic table activation then I can omit Stuff sacks #1,# 2, and #3, but otherwise wear my day pack and battery bag as described above.

Of course, there are always variations, such as using the camera tripod, AXT1, and RG174 coax to set up at a picnic table, but allow the AX1/AXE1/AX2 antenna to be more in the clear (such as operating from a picnic shelter).

I’ve also done what you might call “pedestrian stationary”, deploying the KX2 HT-style and hand-held, but sitting in my backpacking chair.  Or deploying a wire antenna (EFHW or “random”), but sitting in the backpacking chair with the rig balanced on my leg.  By traveling with “everything” but packing in a modular fashion, there are any number of variations on how I can set up for an activation.
