5.7 120 degree sectors

does anybody use 5.7ghz 120 degree v-pol sector antennas? if so how well does it work out and what are the best antennas to use for this?

I use Pacific Wireless or Stella Doradus 120° sector antennas on 5.4 Ghz.
They have 15-16 db gain and perform well.

are those null fill antennas?

I tend to stick with the Last Mile Gear equipment. Its all certified and performs very well. Its worth the extra money everytime!
