ANT-20287EB56

Antennas RF Overview

The ANT-20287EB56 is a wideband cellular whip antenna manufactured by Adam Tech, designed for 2G, 3G, and 4G applications. It operates across two frequency ranges: 698MHz to 960MHz and 1.71GHz to 2.17GHz, with center frequencies at 829MHz and 1.94GHz. The unit features an SMA male connector for installation and supports a maximum power rating of 25 W. Key electrical parameters include gains ranging from -4.5dBi to 4dBi, VSWR values of 5 and 10, and return loss specifications of -1.5dB and -3.5dB. The physical dimensions are 8mm in width and 51.50mm in height.

Antennas RF Procurement Notes

Verify the specific gain and VSWR requirements against the datasheet, as these parameters vary across the supported frequency bands. Confirm that the SMA male connector interface matches the host device's jack. Ensure the 25 W power handling capacity exceeds the transmitter output levels in the intended application environment to prevent component damage.

Antennas RF Selection Notes

Select this model when a wideband solution covering both sub-1GHz and GHz-range cellular bands is required. The compact 51.50mm height makes it suitable for space-constrained installations compared to longer external antennas. Consider the impedance matching and connector type compatibility with the base station or module being integrated into the system design.
