The spacing between the radiating elements of the antenna and the panel is critical. You might find a particular spacing that could even give gain in some circumstances. It needs to be adjusted for lowest loss.

On a particular structure, the tower owner added panels in front of our equipment to great detriment.. Looking for an alternative product that won’t crap on our parade. We performed testing today at 5.8 Ghz.. Here is a table of before and after signals for 5 customers we took measurements from Before / After / Delta HC -56.0 / -57.4 = 1.4 RO -63.7 / -65.2 = 1.5 WB -58.7 / -60.5 = 1.8 SF -59.9 / -61.8 = 1.9 GG -60.7 / -62.5 = 1.8 As you can see the average attenuation of the panel was measured to be -1.68dB (a 20% reduction in signal level).. This is similar to the vendor provided attenuation number of 1.31dB for straight on and -2.66dB for 45 degree [cid:[email protected]] 45 degree angle: [cid:[email protected]] [cid:[email protected]] -Peter
