George, KJ6VU, is a principle in the Pack-Tenna venture and a good
friend. I don't have one but I've seen it. It's a fairly slick package
for field work and it does not need an ATU which might put another 0.1
watt into the radiation resistance instead of heat in the ATU.

PackTenna <http://packtenna.com/> has a end fed half wave antenna with
a 50:1 transformer called the PackTenna Mini:
"This compact wire antenna is ideal for SOTA activations, camping,
backpacking, and travel. The PackTenna Mini End-Fed Half Wave Antenna
combines a 50:1 UNUN, winder and antenna wire in a compact unit that
is quick to set up and take down. The antenna comes with 40' of 26 AWG
copper clad steel wire with a great "silky" jacket to minimize wire
tangle. You can cut the wire to any band from 20 meters and up in
frequency. You can add additional wire for lower frequency bands as
well. This is a single band antenna and does *not* require a tuner."

As others pointed out, to get any real benefit from the EFHW it needs
to be a real half wave or very close to it, necessitating a
transformer to shift the impedance into range of the ATU or a
purpose-built matching network (tuner). Shifting the length from a
half wave simply turns the wire into a "random wire".
