2.14.3 Antenna checklist
Antenna termination should provide 50 Ω characteristic impedance with V.S.W.R at least less than 3:1
(recommended 2:1) on operating bands in deployment geographical area.
Follow the recommendations of the antenna producer for correct antenna installation and deployment (PCB
layout and matching circuitry).
Ensure compliance with any regulatory agency RF radiation requirement, as reported in section 4.2.2 for United
States and in section 4.3.1 for Canada.
Ensure high isolation between the cellular antenna and any other antennas or transmitters present on the end
device.
