[Elecraft] {OT} Alexloop Walkham Antenna

[Chip Stratton]

On some SOTA activations I will start off running my KX3 at 1 watt with my
AlexLoop to try to reduce the initial pile-up to a more manageable level.
Sometimes it works, and sometime it doesn't seem to matter, there is still
a pile-up!

The most important thing when using the AlexLoop is to be able to see the
SWR change continuously as you tune it. If your transmitter has a good SWR
indication you should be fine.

I suspect you would be pleased with its performance even at 1-2 watts.
