Product details

GL-DY403-4G is a short external antenna built around a Ø10.5 × 53.7 mm housing. Compare that physical envelope with the available space around the equipment connector, including nearby sockets and moving covers. The SMA male connection must match the equipment contact as well as the connector shell.

Check the working channels against the model-specific frequency information and test data rather than assuming compatibility from the 4G model suffix. The linear polarization should guide antenna orientation in the completed installation. Use the test table and plots below when reviewing matching, then evaluate the antenna on the actual enclosure. Its 2.5 dBi gain entry does not replace that integration check or establish a particular communication range.
