Evercom’s GSM antenna category includes base-station, Yagi, wall-mount, window-clip, patch, on-glass, marine, trucker, portable, NMO, roof and magnetic formats. These groups address different mechanical installations. The exact GSM/UMTS bands, gain, connector and cable configuration must be confirmed for the selected model and target network.
Confirm that the intended market and operator still support the required cellular service, then provide the modem bands and installation type. Compare frequency range, antenna pattern, polarization, gain, impedance, connector, cable length, mounting surface, ground-plane requirement and environmental exposure. For vehicle or outdoor use, also review vibration, sealing, cable routing and service access.
List the modem-supported bands, target country and operator rather than using only a general GSM label. Common allocations vary by market, and network availability may change, so the antenna and service plan should be checked together.
The mounting surface determines available ground plane, orientation, cable path and weather exposure. Select the mechanical format first, then verify that the exact RF model covers the required bands and connector configuration.
