The HG2458RD-SM from HyperLink is a high performance tri-band rubber-duck antenna that operates from 2.4 GHz to 2.5 GHz, 4.9 GHz to 5.3 GHz and 5.7 GHz to 5.8 GHz. The tri-band design of this antenna helps reduce interference and noise as it rejects out-of-band signals between the three bands. This omnidirectional rubber-duck antenna provides a gain of 3 dBi and can handle up to 50 Watts of power. It measures 7.79" in length and 0.51" in diameter and features a tilt-and-swivel SMA male connector which allows it to be used vertically, at a right angle, or any angle in-between. This antenna is suitable as a replacement RF antenna for many wireless access points and routers that are equipped with similar antennas.
