Two black dual-band SMA male WiFi antennas with hinged bases

BFKK

BFKK Dual Band WiFi Antenna 3dBi SMA Male 2-Pack

SKU CH-HFA9-3EE2X

Dual-band 2.4 GHz and 5.8 GHz SMA male antennas supplied as a pair for IP cameras, DVRs, vehicle backup monitors and industrial wireless gear

Color SMA Male Antenna 2-Pack

  • Dual-band coverage from 2.4 GHz to 5.8 GHz for flexible wireless links
  • Two SMA male antennas included so both transmitter and receiver can be upgraded
  • Works with IP security cameras and wireless video recorders for clearer surveillance footage
  • Compatible with truck rear-view and backup cameras to strengthen mobile video signals
  • Suitable for 5.8 GHz FPV drone gear and wireless AV extenders for low-latency video

Dual Band WiFi Antenna 3dBi SMA Male

This dual band antenna kit covers 2.4 GHz from 2400 to 2485 MHz and 5 GHz from 5150 to 5850 MHz. It fits SMA male connectors on IP security cameras, wireless DVR recorders and truck rear view monitors. The pair also works with 5.8 GHz FPV drone controllers and industrial IoT gateways.

Passive operation with no power draw

These antennas add no active components to the signal chain, so they draw zero power and produce no noise. They simply replace the stock whip on compatible equipment to extend range or improve reception in obstructed areas.

Replaces short stock whips on SMA devices

The upgrade is worthwhile when the factory antenna cannot reach a distant access point or suffers multipath interference. Buyers who need MIMO spatial streams or connector types other than SMA male should look elsewhere.

Questions about this item

How do I install the SMA male antennas on my camera or router, and what is the common mistake?

Screw each SMA male connector clockwise onto the female SMA port of the camera, router, or monitor until snug; the common mistake is cross-threading or leaving the connection loose, which degrades the 2.4 and 5.8 GHz signal.

What maintenance or replacement will these antennas need over time?

No active maintenance is required; inspect the SMA threads and rubber housing periodically for corrosion or physical damage, and replace an antenna only if the connector is stripped or the element is cracked.

What is the first limit that appears when these antennas run continuously in a surveillance or FPV setup?

The practical limit is the fixed 3 dBi gain and the 2400-2485 MHz and 5150-5850 MHz band edges; beyond those frequencies the antennas cannot radiate, and sustained high-power transmission may overheat the small element.
