HighZer0 Electronics RFANT17Z+M4 MHF4 Patch Antenna Pair 50cm

Internal MHF4 WiFi Antenna Pair

This HighZer0 Electronics antenna pair replaces weak, damaged, or missing internal WiFi antennas in laptops, desktops, motherboards, routers, embedded systems, and small form factor builds. It connects to M.2 or NGFF wireless cards such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW, and 7265NGW that use MHF4, IPEX4, or 4th Generation U.FL connectors. The set suits builders who prefer clean, hidden antenna wires over external posts or bulky add-ons.

Peel-and-Stick Placement Inside Tight Chassis

Each 50cm cable uses a flexible FPC/PCB radiator with a pre-applied double-sided adhesive pad. Peel the backing and press the pad onto a suitable surface inside the case, laptop lid, or enclosure to lock placement, conceal wiring, and route the low-loss RF1.13 coax through confined spaces. The connector fits only MHF4, IPEX4, or 4th Gen U.FL ports; it will not mate with MHF1, IPEX1, or 1st Gen U.FL connectors found on many mini-PCIe or Half-Mini PCIe cards. Verify the connector size and existing antenna end before ordering to avoid a mismatch.

2.5dBi Gain Across 2.4GHz, 5GHz, 5.8GHz.

The omnidirectional, vertically polarised antennas present a 50 Ohm impedance with SWR below 2 and handle up to 2W input power. They deliver 2.5dBi maximum gain for stable WiFi and Bluetooth reception across the 2.4GHz, 5GHz, 5.8GHz, and 6GHz frequency ranges. Performance is limited by the short 50cm cable length and the compact patch design; builders needing longer runs, higher gain, or external mounting for challenging RF environments should consider alternative antenna solutions.
