Internal Wi-Fi Antenna Kit

This HighZer0 Electronics kit contains one pair of 40cm internal antenna cables with MHF4 connectors. They suit laptops, desktops, motherboards, routers and embedded systems using M.2 wireless cards. The flexible FPC radiators have adhesive backing for concealed routing inside tight enclosures.

Upgraders With M.2 Cards Only

Builders repairing missing or damaged internal antennas on AX200, AX210, BE200 or similar M.2 adapters will find the correct 4th Gen U.FL fit here. Anyone with mini-PCIe Half-Mini cards using MHF1 or 1st Gen U.FL ports must choose a different cable set.

Connector Generation Is Decisive

The cables terminate in MHF4, IPEX4 and 4th Generation U.FL plugs that match 4, 200, 210, 211, 7265, 8265, 9260 and 9560 series M.2 cards. They will not seat on the smaller MHF1 connectors found on older mini-PCIe wireless adapters.

Questions about this item

What connector size does this antenna cable use to fit an M.2 WiFi card?

The cable ends are MHF4, IPEX4 and 4th Gen U.FL plugs that match the antenna ports on M.2 NGFF cards such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW and 7265NGW.

How is the antenna pad secured inside a laptop or desktop case during installation?

Each pad has a pre-attached double-sided adhesive; peel the liner and press the pad onto a clean, flat surface inside the chassis or lid to lock placement and conceal the wire.

When should the antenna pair be replaced or checked for wear?

Inspect the RF1.13 coax and adhesive pads if WiFi or Bluetooth range drops, after a chassis impact, or whenever the device is reopened for service; replace the pair if the cable sheath is kinked, the connector feels loose, or the pad no longer holds.
