Bob, > no matter what I do it will never work the first time
LOL, but actually you hit the nail on the head on that comment. No one can conculsively predict an unknown environment. The odds are 50/50 one will guess right. In my mind thats the biggest advantage of Dual Pol sectors for towers, "insurance". Pay an extra $300 bucks upfront, and guarantee that you dont have to pay $2000 later to re-climb the tower, and replace antenna, to correct a wrong guess. We also find it hard to teswt the results from remote potential CPE locations, while climbers are on the tower. Just not enough time. So much easier to do field survey testing the nxt day, and at that time select the polarity that is best.
