The foundation of a reliable radio network is the RF Site Survey. The EST Customer Support engineer performs on-site measurements and analysis to determine factors needed to design the RF data communications system including RF signal levels between all nodes, co-channel emitter frequencies, their signal strengths, and RF data quality. Additional design input is given on antenna selection and location, feedline requirements, and lightning/power protection for each node, as well as specific installation requirements as dictated by the customer's application. After completion of the analysis, a formal Site Survey Report is prepared to document the above findings and the installation/hardware requirements for the site.
