I saw someone asked this similar question but didn’t get a reply. Is it ok to use deflector in US to get extra distance with 5200?
Why use 5200 instead of 5700?
Because of FCC regulations no. But in other conuntries its ok.
5200 PTMP cannot use reflectors.
5200 PTP can use reflectors and/or dishes.
5.2 GHz Extended Range Backhaul Module w/ Reflector 10 Mbps
Antenna Gain = 7db
Reflector Gain = 18 db
EIRP = 30 db (1.3W)
LOS Distance: 10 miles
Rx Sensitivity: -86 dbm
5.2 GHz Extended Range Backhaul Module w/ Reflector 20 Mbps
Antenna Gain = 7db
Reflector Gain = 18 db
EIRP = 30 db (1.3W)
LOS Distance: 5 miles
Rx Sensitivity: -79 dbm
These are from PDF Spec Sheets from 2004. The most recent version of a BH that I have used in 5.2 GHz was a 10 Mbps with reflectors on both ends. It came with software version 7.x.x.?? which had an option to adjust the power output of the radio. I called Moto since I was not familiar with this setting. They asked me what it was set to. I told them. They said from the factory, the transmitter is set at the highest output power allowed by FCC law under the assumption that reflectors were being used.
I think the link ended up being around 3 miles in distance and the Rx level at the BHS was -46 db!!
