So, I need to conduct an RF survey of a ground site. The survey’s purpose is to determine if there is any QRM in the area of a ground site receiving UHF radio signals for GNSS with RTK radios.
What is QRM? It’s an amateur radio shorthand for man made noise encountered when trying to receive a signal. That’s what we are looking for here. Any noise, man made or natural (QRN) interference.
The antenna is cut for 450 MHz.
