What this antenna pair is for

This HighZer0 Electronics RFANT12Z+M4 kit replaces weak, damaged, or missing internal WiFi antennas in laptops, desktops, motherboards, routers, embedded systems, and small form factor builds. It suits any M.2 or NGFF wireless card that uses MHF4, IPEX4, or 4th Generation U.FL antenna ports. The adhesive-backed pads let you conceal the 20cm cables inside tight chassis or laptop lids without external posts.

Connector compatibility decides fit

These antennas connect only to MHF4, IPEX4, and 4th Generation U.FL ports found on cards such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW, and 7265NGW. They will not fit MHF1, IPEX1, or 1st Generation U.FL connectors used by many mini-PCIe or Half-Mini PCIe HMW cards. Verify the connector size and card style before ordering.

Thermals noise and power in normal use

The antenna pair is entirely passive, so it generates no heat, produces no noise, and draws no power from the system. It handles up to 2W maximum input power with a 50 Ohm nominal impedance and SWR below 2 across 2.4GHz, 5GHz, 5.8GHz, and 6GHz bands. The low-loss RF1.13 cable preserves signal quality without adding thermal load.

Questions about this item

What does the 2.5 dBi gain mean for signal strength inside my laptop or desktop?

The 2.5 dBi omnidirectional gain provides a modest boost to reception across 2.4 GHz, 5 GHz, 5.8 GHz and 6 GHz bands, helping to stabilise Wi-Fi and Bluetooth links in tight internal spaces without needing external posts.

Which connector standard does this pair use, and what cards does it fit?

The cables terminate in MHF4 / IPEX4 / 4th Gen U.FL plugs, matching M.2 / NGFF Wi-Fi cards such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW and 7265NGW.

How much room do I need to route the 20 cm cables and stick the pads down?

Each antenna has a 20 cm low-loss RF1.13 coax and a pre-applied double-sided adhesive pad, so you only need enough clearance to peel, place and route the thin flexible cable inside the chassis or laptop lid.
