Two black RP-SMA male WiFi antennas with magnetic bases and 6.5 ft cables

KEHIPI

KEHIPI 2.4/5.8 GHz dual-band RP-SMA WiFi antenna 2-pack with IPEX MHF4 cable 9.8 in

SKU CH-EA9X-3TA58

Dual-band 2.4 and 5.8 GHz RP-SMA antennas with 9.8-inch IPEX MHF4 cables add 6 dBi omnidirectional gain to M.2 NGFF cards and routers

Option RP-SMA Antenna+m.2 ngff card cables

  • Dual-band 2.4 and 5.8 GHz coverage extends Wi-Fi 6 range
  • 6 dBi gain boosts signal strength for routers and PCIe cards
  • Omnidirectional pattern receives from every direction without aiming
  • Magnetic base plus screw slots allow metal or wall mounting
  • 5 ft IPEX MHF4 cables give flexible antenna placement

Dual-band RP-SMA antenna kit

The KEHIPI 2-pack supplies two omnidirectional antennas with dual RP-SMA male connectors and integrated magnetic bases. They cover the 2.4 GHz and 5.8 GHz bands with a stated 6 dBi gain and 50 ohm impedance. Each unit includes a 200 cm IPEX MHF4 to RP-SMA female pigtail plus a 9.8 inch cable for flexible placement. The set targets desktop PCs with M.2 NGFF cards, routers, USB adapters and FPV gear.

Practical limits of the RP-SMA interface

RP-SMA uses a reverse-polarity centre pin, so the antenna plugs only mate with matching RP-SMA jacks; standard SMA ports will not connect without an adapter. The 6.5 ft extension cables add insertion loss that grows with frequency, which can reduce the effective gain at 5.8 GHz compared with a direct mount. Omnidirectional radiation spreads energy horizontally, so vertical obstacles such as metal shelves or thick walls still attenuate the signal despite the 6 dBi rating.

Check your existing setup before ordering

Verify that your network card, router or FPV receiver exposes RP-SMA female ports; count the available jacks to confirm two antennas can be fitted simultaneously. Ensure the IPEX MHF4 pigtail matches the on-board connector on your M.2 module, as some cards use MHF1 or U.FL instead. Confirm there is a ferrous surface or wall area for the magnetic base or screw slots if you plan to position the antennas away from the chassis.

Questions about this item

One pack says 6.5 ft cable and the other 9.8 in — which length should I choose for a desktop PC?

The 9.8 in IPEX MHF4 pigtail connects the M.2 card to the bulkhead; the 6.5 ft RP-SMA extension then runs from the bulkhead to the magnetic-base antenna, so both lengths are used together.

The box states 6 dBi gain — what does that deliver on a typical Wi-Fi 6 router?

6 dBi focuses energy horizontally, boosting range on the same floor while reducing coverage directly above and below the antenna.

My card has an MHF4 socket — will the RP-SMA male plugs on these antennas mate directly?

No, the antennas terminate in RP-SMA male; the included 9.8 in pigtail converts MHF4 to RP-SMA female so the two can connect.
