[Elecraft] HF Stealth Loops

[W1GO (Joe)]

Prefer the W4OP loop due to ruggedness and remote tune feature. Yes, its heavier but how many of us actually hike to the top of a big mountain?  

What would be great, however, would be a mag loop that the KX2 or KX3 could remotely tuned from the rig.  I’d pay for that ...

> A magloop inside a backpack next to the human body probably won't work because the loop is detuned by the human, and that tuning varies with the distance.  If you are walking, tuning would be difficult because the pack will jiggle, varying the distance--unless you could glide motionless over the ground (or water).  I suspect Wayne could do this, but probably not in public.  Even when you use a magloop on a tripod, you have to tune it using an offset so it is in the right place when you step away.  This quickly becomes intuitive once you know how much, and which way, to turn the tuning capacitor.

> The advantage of magloops is their small size, quick setup, and needing neither a counterpoise nor more height above ground than one loop diameter.  If you go to a public park and want to talk to a ranger, setting up a magloop will materialize one as if by magic.  Magloops are terrific chick magnets, kid magnets, and will get you in heated arguments with people who have never used one.
