I did work a few stations in Europe on 80m with my Gap Titan.  But I sure
wouldn't recommend it.  You have to order the antenna for the 100kHz portion
of the band you wish to work also.  It is not adjustable on that band.  They
change a capacitor in the very top of the antenna for the portion you wish
to use.  Tuners are not recommended when using full power.  You can wipe out
the cap.

On other bands, it seemed to work well for a multiband-one feedline antenna.
Sometimes you can crush a pileup and sometimes they seem deaf to you.  Mine
worked best mounted near the ground.  When 12ft in the air it shifted
resonance on 40 & 80m and narrowed the bandwidth.  But worked better on 10,
12 & 15m during the low point in the sunspot cycle.
