I believe we are having the same problem. We are having some major issues with interference with our new Mimosa tower. It is collocated with a 150mhz first responders repeater on a water tower. At first the equipment was causing desensing with their equipment. We were able to stop the desensing, but we are still causing a bunch of noise and limiting the range of their equipment. It seems to be worse at night. They have given us one week from today to get it resolved or be removed. I have tried contacting support, but they unfortunately were not very helpful.
We have the following equipment on the tower: (see image for placement https://1drv.ms/i/s!AluucxSLDl7Mh6Iw6h0JkV2cazF2mg)
4x A5c w/KP X4 17.6 dBi Antenna
1x B5c w/ antenna
WISP Switch WS-12-250-AC
We have done the following to clean it up as much as possible:
All devices are grounded
All devices are covered in TDK IFL12 RF Absorbing Sheets
All Devices are then covered in EMI Shielding Copper Foil Tape
All cables have ferrite rings on both ends
Using an RF Explorer, in the air around the devices we no longer see much noise in the 150Mhz range. But we do see a great deal of noise when we touch the shielding on the devices or the railing that they are mounted to.
We have tried isolating the device mounts from the tower using rubber, with the only ground source being the ac power coming up the tower. But that did not help.
Was anyone able to get this fully resolved? We have already ordered replacement equipment from another vendor, but we are hoping to get this working instead.
Anyone have any ideas on other things to try?
