2.4G 5G 5.8G Dual Band RP-TNC 6dBi Antenna Kit for Linksys WRT54GL WRT54G WRT54GS WAP54G WRT54G-TM Omni WiFi w/ RP-TNC connector Signal Booster for Cisco Linksys Router
Omnidirectional dipole antenna: Radiates signal with a beam of 360 degrees; also receives a signal from 360 degrees around it.

It is suitable and compliant for all the following applications:.

IoT wireless & M2M: Bluetooth, ZigBee, and ISM. Since it is vertically polarized, it is compatible with many machine-to-machine communication applications, remote monitoring, and telemetry applications.
2.4GHz WiFi applications: 802.11N, 802.11G, 802.11B.
Compatible with Bluetooth devices, Wireless Access Points & other wireless devices. As Bluetooth antenna: Send or receive signal to devices in all directions (360-degree horizontal beamwidth).
As client antenna: Connect to access points in any direction. Portable size: Easily fits in a laptop case..
.
Compatible with Wireless Access Points & cards that have RP-TNC antenna jacks: Cisco/Linksys Wireless Access Points have an RP-TNC (female) jack that is compatible with this antenna..
RP-TNC Connector Characteristics and Details:

This can be used to mount the connector (and thus the cable) on the wall of a network enclosure (to weatherproof the cable connection ) or mount the connector on a case, panel, or Printed Circuit Board (PCB).
Weatherproofing: Seal the hole where the female connector is mounted, by placing an O-ring between the wall of the enclosure and the bulkhead nut & washer on the female connector.
RP-TNC is a round screw-type connector, with nickel-plated brass.

Nickel-plated brass is the best plating alloy for corrosion resistance.
RP-TNC is similar to BNC except that whereas BNC has a slotted mating collar, RP-TNC has a screw-down type connector. RP-TNC's screw-down connector performs better than BNC in the microwave spectrum.
