Two black RP-SMA male WiFi antennas with 12 inch u.fl cables

KEHIPI

KEHIPI Dual Band WiFi Antenna 2.4GHz 5.8GHz 3dBi RP-SMA Male 2-Pack + 12 inch u.fl Cable

SKU CH-B9SA-3NXJ4

Dual-band 2.4 GHz and 5.8 GHz antennas with 3 dBi gain, RP-SMA male connectors and two 12-inch u.fl cables for routers or PCIe cards

Option Antenna for Mini Pcie Card

  • Dual-band coverage from 2.4 GHz to 5.8 GHz for wider compatibility
  • 3 dBi gain boosts signal strength on routers and adapters
  • RP-SMA male plug fits female sockets on PCIe cards and industrial gear
  • Omni-directional pattern sends signal evenly in all directions
  • Includes two 12-inch U.FL cables for flexible internal routing

Dual-band 3 dBi antennas

This dual-band antenna set covers 2.4 GHz (2400-2485 MHz) and 5.8 GHz (5150-5850 MHz) with 3 dBi gain. Each unit uses an SMA male connector and includes a 12 inch u.fl to RP-SMA cable. The omni-directional pattern suits routers, PCIe network cards and industrial IoT gateways.

Suits SMA-female ports only

Builders with SMA female jacks on routers, mini PCIe adapters or FPV video gear can attach these directly. The package also supports 2.4 GHz Bluetooth audio devices. Buyers needing N-type, TNC or reverse-polarity SMA connectors should look at something else because the plug geometry will not mate.

3 dBi gain decides range

The 3 dBi figure determines how much signal focus the antenna adds over a bare connector. Higher-gain units would narrow the vertical beam, while lower-gain models radiate more broadly. Check your link budget and mounting height to confirm this gain level matches the coverage you need.

Questions about this item

How do I install the RP-SMA male antennas onto my device, and what is the common mistake?

Screw each SMA male plug into a matching SMA female jack until finger-tight; the common mistake is forcing an RP-SMA connector onto a standard SMA jack, which have opposite pin arrangements.

What maintenance or replacement will the antennas and u.fl cables need over time?

Inspect the 12-inch u.fl cables for kinks or loose crimps and check the antenna housings for cracks; replace any cable or antenna showing physical damage or degraded VSWR.

What is the first performance limit reached under sustained high-power transmission?

The VSWR limit of < 2.0 is the first constraint; exceeding it causes reflected power and heating, so keep transmit power within the antenna's 50-ohm design envelope.
