Robert,
I've found that the KX3 ATU loads up a 58' endfed wire just fine on all
bands, but it can't load up everything. The 67' endfed wire I have
(which, in theory, is very tough to load up) could be loaded up on 20
with the K1 ATU. The KX3 ATU can not handle it.
So, for your loop, depending on the size, you may or may not have
trouble depending on the length. For a closed loop I believe you want to
avoid odd multiples of half wave lengths. If the possible length you
have is pretty inflexible and the KX3 ATU can't handle it you can try
inserting an insulator half way around making it an open loop.
73,
Niel - W0VLZ
