Eight black U.FL to RP-SMA female pigtail cables coiled together

Vszerda 8PCS 20CM U.FL to RP-SMA Female Pigtail Cable RG178 50 Ohm network antenna

SKU CH-BBJZ-4S249

Set of eight 20 cm U.FL to RP-SMA female pigtail cables using RG178 50 Ohm coax for Mini PCI-E wireless cards

  • Product colorBlack
  • 8 cables let you equip multiple Mini PCI-E cards
  • 20 cm length keeps signal paths short inside tight chassis
  • RG178 50 Ohm coax maintains low-loss 5.8 GHz links
  • U.FL to RP-SMA female fits laptop Mini PCI-E Wi-Fi cards
  • Not compatible with M.2 NGFF interfaces — verify card type first

Eight-Pack U.FL to RP-SMA Pigtail Cables

This set supplies eight 20 cm coaxial jumpers that convert a U.FL (IPEX 1) connector on a Mini PCI-E wireless card to an RP-SMA female bulkhead. Each cable uses RG-178 construction rated at 50 Ohm impedance. The pack is aimed at technicians adding external antennas to laptops, embedded boards or FPV gear that expose a U.FL jack.

Sustained Signal Integrity Over 20 cm

RG-178’s thin dielectric keeps insertion loss low across the 20 cm run, so 5.8 GHz FPV video or 5 GHz Wi-Fi links maintain stable throughput during long flights or extended streaming sessions. The 50 Ohm match prevents standing-wave buildup that would otherwise degrade sensitivity after minutes of continuous transmission.

Mini PCI-E Only — Not M.2 NGFF

The U.FL plug fits Mini PCI-E cards with an IPEX 1 antenna port; it will not seat in M.2 NGFF keyed slots. Builders needing antenna leads for newer M.2 wireless modules must source a different pigtail family. The RP-SMA female end accepts standard SMA-male antennas used on 5.8 GHz FPV cameras, video transmitters and wireless AV extenders.

Questions about this item

Does the 50 Ohm RG178 cable add noticeable heat or power draw when the antennas run all day?

The passive 50 Ohm RG178 pigtail adds no power draw and generates no heat; it simply routes the RF signal from the card to the antenna.

What must my Mini PCI-E card already have for these U.FL pigtails to connect?

Your Mini PCI-E network card needs a U.FL (IPEX 1) external antenna connector; the pigtail plugs directly into that jack.

Will these 20 cm pigtails work with an older Mini PCI-E card that only has a single U.FL port?

Yes, each cable connects one U.FL port to one RP-SMA antenna, so a card with a single U.FL jack uses one pigtail from the eight.
