Just curious if anyone might have any thoughts on any good 160 verticals.
 I saw the Gladiador in NCJ ...curious abt it.

Do these arrays operate on only one band,  that is spaced only for
160 or 80,  or do they phase properly on each of the low bands
with one physical set up?

No,  the Gladiators are monobanders,  optimized for efficiency and
bandwidth by band.

Other scores posted so far by Jimmy Floyd, K4ZAM for 160 performance
during the ARRL test,  and in the same catagory as W1XT with his Gladiator
TL160,  and in the 7 call district,  only two are in Arizona:

W1XT  was  23 by 18 multis on 160

KC7V    was  10 by 8 in Az,

N7IR     was     also 10  by  8,  but he was  QRP on 160! and in Az,

W7WHY   was  2  by  2,  but he is in Oregon state,

W7VV  was  2  by  2,  but he is in Washington state,

K7BG  was  16 by  12,  but he is in Montana.

Two other 7's,  but Hawaiian 7's also have posted scores:

NH7A on Maui  got  156  by  42 on 160

KH7R  on Oahu  got  283  by  51  on 160.

Maybe that almost nonbelievable Hawaiian soil conductivity really
does work!  And of course,  Jack,  KH6CC down on the Big Island
is a 160 band DX icon!!  Hard to believe that Hawaiian soil is
an order of magnitude higher conductivity because of
volcano rich mineral content than mainland soils,  see my
previous posts.
