U.FL/IPEX to N-Female Pigtail Cable — RG178 LoRa Antenna Pigtail for Heltec, WisBlock & MeshCore Builds

The missing link between your dev board and a proper outdoor antenna. This U.FL (IPEX/MHF1) to N-Female pigtail cable connects any LoRa board with an IPEX antenna connector — like the Heltec WiFi LoRa 32 V3/V4, Wireless Tracker V2, WisBlock starter kits, and Seeed XIAO boards — to N-type antennas, mounting hardware, and outdoor enclosures. If you're building a solar Meshtastic or MeshCore node, mounting a board inside a weatherproof enclosure, or connecting to a McGill outdoor antenna, this is the cable you need. Key Features U.FL (IPEX/MHF1) male connector — snaps onto the IPEX socket on Heltec, WisBlock, Seeed XIAO, RAK4631, and most LoRa development boards N-Female bulkhead connector — with O-ring seal and locking nut. Mounts directly through enclosure walls (IP66/IP67 compatible) for a clean, professional finish RG178 coaxial cable — flexible, thin (1.83 mm diameter), and low-loss for short interconnect runs at 868 MHz 20 cm length — the right length for routing inside a typical enclosure without excess slack 50Ω impedance — matches all standard LoRa radio modules and antennas Frequency range: DC – 6 GHz (perfect for 868 MHz EU868 LoRa) What This Cable Lets You Do Most LoRa development boards ship with a small stock antenna that screws directly onto the IPEX connector. That works for testing — but for any serious build, you want: An external antenna — either a flexible whip on the outside of an enclosure, or a proper outdoor antenna on a pole A weatherproof mount — by passing the antenna connection through the enclosure wall with a sealed N-Female bulkhead A larger tuned antenna — like the McGill 3, 6, or 9 dBi outdoor antennas (all with N-Female connectors) This pigtail makes all three possible. Connect the U.FL side to your board, route the cable through your enclosure, screw the N-Female bulkhead into the wall, and connect your external antenna outside.
