Not ,the same downtilt angle, same percentage as the old one. The previous antenna was a Tranzeo 16db w/6 degree vertical, the Teletronics 19db has a 8 degree vertical actually larger VB then the 16db at 6. They are both at .3 degrees downtilt. The only reason I mention the VSWR is because the teletronics VSWR is 1.1:4, vs 1.5 on the Tranzeo. The Teletronics is down about 6db on the CPE side for all the clients on the test sector, on the AP side it's the same. I tested multiple tilt's as well, between 0-1 degree was the best on the CPE side.
