Now don’t be dissing dowsing... I have made many believers. One subdivision/industrial park I developed had a 100 year old underground aqueduct that feeds RioTinto’s copper mill running through it. Critical infrastructure for Rio Tinto but they cannot find it if called for a locate. They just say it is out in that field and we better not hit it.
I used my favorite type of brass rods and found it, found the center of it (it is about 4’ wide and 6 feet deep concrete rectangular ditch with an arched top). When we used the vacuum excavator, my mark was top dead center. I marked it at about a half dozen locations and was always spot on. I have no clue how it works but I have always had great success with it.

I think we walk away from about 50% of the 900 MHz installs we go to. If we can’t find a spot where we get an actual peak while aligning the antenna, but rather just the same weak signal everywhere we point the antenna, we know that we’re just picking up scattered signal off the trees and it’s not going to be fast or reliable, even if it does actually register and pass data. We definitely have RTK and smartgrid interference in 900 MHz, but my theory is when we are just getting a scattered signal from our AP, we are also getting scattered signal from other 900 MHz WISPs in the area and can’t aim the antenna to differentiate between the APs at different azimuths. And GPS timing does not help when an SM is seeing several APs. OK, just my theory. Maybe since we mostly do LOS we don’t understand the NLOS magic tricks, like maybe we need to be sacrificing livestock at every install or chanting magic incantations. Or maybe like dousing for water, you need to be a true believer.

It's our worst case test site. We have a LOT of customers on 900 FSK. Old abandoned 75 foot cable TV tower, so it's not even above the trees. But we're getting customers off of 900 which is the most important thing. Getting 30Mbps to a customer that could get only 1Mbps before is an improvement to say the least. I didn't think it'd be viable given the height limitation and tree density, but it's working rather well. We're going to swap out the MTI antenna for a KP and see what we get.
