I was curious if anyone has found or attempted to make RF sheilds to put behind sector antennas? With the 2.4ghz noise floor continuing to rise and for tower sites with multiple sectors without the ability to use all three non-overlapping channels, I could see a need for this.
I have a site with 3 sectors and each radio see's the others as -5 to -20 because of the strong back lobes. I can be a mile away from the tower and pickup signal on all three sectors (90 degree). The one with the main lobe in that area is always stronger but that just tells me that the sectors that are servicing users in the other direction is picking up noise from behind it that it shouldn't even be seeing.
Anyone have any thoughts on this?
