Foghorn affects on Radar and DGPS

We are mounting a High Power Automated Foghorn on a tower within 3 meters from a 10cm ,3cm Radar and DGPS. Has anyone heard of any problems associated with mounted a high powered horn close to radar and gps? Or has regs restricting it ?


a similar experience…ET’s once installed a gps antenna with a pre-amp directly in line to the radar array on a vessel I worked…gps functioned erractically…when we checked the manual this was specifically not recommended in the installation directions…ended up replacing the antenna and relocating it well above the arrays when we got to Panama…concluded if it can be avoided it is best not to mount anything electronic within the radar arrays.
