Window feed-through for 4x4 MIMO 5G / 4G Antenna - 50cm, SMA Male / Female
The JARFT J2250-SMA 4x4 MIMO 5G/LTE window feed-through is the perfect solution for connecting a 4x4 MIMO 5G or LTE outdoor antenna to your indoor router or access point without the need for drilling. With a length of 50 cm and an ultra-flat design, the window cable can be easily routed through or laid inside a window frame without damaging or affecting the frame, window, or locking mechanism.

Equipped with four SMA plugs and four SMA sockets, the feed-through ensures a secure and low-loss connection between the antenna cable of your 4x4 MIMO 5G/LTE antenna and the antenna cable or directly to the antenna ports of the router or access point.

This SMA window feed-through is also available in a simpler version as well as for 2x2 MIMO in our range. Additionally, we offer this feed-through for use with WiFi antennas.
