Internal WiFi antenna pair

This 1-pair HighZer0 Electronics antenna set upgrades or replaces weak, damaged, or missing internal WiFi antennas in motherboards, desktops, laptops, routers, embedded systems, and SFF builds. Each antenna uses a 30cm low-loss RF1.13 coax cable with an FPC/PCB radiator and pre-attached double-sided adhesive pad for secure, concealed placement inside tight spaces.

MHF4 IPEX4 4th Gen U.FL fit

Connectors match MHF4, IPEX4, and 4th Generation U.FL ports found on M.2 / NGFF wireless cards such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW, and 7265NGW. The 30cm flexible cables route cleanly inside cases, laptop lids, or enclosures, freeing builds from external antenna posts and bulky add-ons while supporting hidden internal routing.

2.5dBi omnidirectional gain

Antennas cover 2.4GHz, 5GHz, 5.8GHz, and 6GHz WiFi and Bluetooth bands with 2.5dBi max gain, vertical polarization, 50 Ohm impedance, 2W max input power, and SWR under 2 for stable reception. Lightweight FPC/PCB radiators and RF1.13 cable keep insertion loss low in normal operation without adding active cooling or noise.

Questions about this item

What is the maximum input power the RFANT11Z+M4 antenna can handle before performance drops?

The antenna is rated for a maximum input power of 2W, which is the limit that appears first under sustained high-power transmission.

How much heat or noise does the antenna generate during continuous all-day operation?

As a passive component with no active electronics, the antenna produces no noise and negligible heat during continuous use.

Which wireless card connectors must my hardware already have for this antenna pair to work?

Your M.2 or NGFF WiFi card must use MHF4, IPEX4, or 4th Generation U.FL antenna ports, as found on models such as AX200, AX210, AX211, BE200, BE202, 9260NGW, 9560NGW, 8265NGW, or 7265NGW.
