I would appreciate experience-based opinions on the quality,
durability, effectiveness, and convenience of Yaesu's ATAS-100
and ATAS-120 auto-tune multiband antenna system.

I haven't used them, but I've examined an ATAS-100 directly. I was thinking
of buying it.
Looks pretty "inexpensive" relative to the other screwdrivers out there.
I didn't think it would hold up in use.
I have the 847.

So far, I haven't found my price/performance point.


There is also a third-party controller from W4RT which claims
to make any "screwdriver" type antenna compatible with the
ATAS functions in the Yaesu FT-847, 857, and 897 ...

Yaesu has an interesting system. Two voltages, one voltage says "go up" and
the other one says "go down". It's not complicated to decode
