Product details
GL-DY4021 combines a Ø10 × 108.5 mm body with an SMA male connector. When comparing it with a similar-looking rubber antenna, check the ordered frequency configuration and the connector contact rather than choosing by shape alone. The installation needs clearance around the equipment socket as well as room for the full antenna length.
The antenna is linearly polarized, so its operating orientation should be consistent with the intended link. Review the matching requirement at the actual working channels and test it on the equipment enclosure. The 2.5 dBi gain entry does not establish compatibility with a particular radio or predict range on its own. Confirm the exact model and interface before substituting it for another antenna in the same housing style.
