Very well constructed antenna that has given excellent results on a trimag mount on top of my car. Whilst sat in a non-optimal position (no clear line of sight to the horizon with terrain on all sides and buildings fairly close), I'm comfortably getting into repeaters 15+ miles away and have had one simplex contact at about 10 miles (all with 5w).
VSWR not going above 1.2 across 2m and 70cm bands. Very happy with this.
