Kabelmeister Coaxial HF Window Feed-through Cable SMA Male to SMA Male, 0.2 m, 50 Ohm, Transparent

This Kabelmeister coaxial HF window feed-through cable delivers a flawless 50-ohm signal path through walls and window frames, with a frequency range up to 6 GHz and gold-plated SMA connectors ensuring minimal loss. Engineered for professional installations, it eliminates the need for drilling while maintaining excellent RF performance.

Overview

The Kabelmeister FD-S20MM is a precision-engineered coaxial cable designed for feeding high-frequency signals through windows, doors, or other thin barriers. Its flat, transparent FEP jacket is nearly invisible when installed, and the pre-attached SMA male connectors on both ends allow for immediate connection to antennas, routers, or measuring equipment. With an impedance of 50 ohms and a length of just 0.2 meters, it is ideal for short, low-loss patching in tight spaces.

What stands out

• No-drilling installation: the flat profile slips easily into window or door frames, preserving building integrity.
• Broad frequency support from DC to 6 GHz, covering WLAN, LTE, GSM, DVB-T2, and amateur radio bands.
• Gold-plated SMA contacts for corrosion resistance and reliable signal transfer.
• Transparent FEP jacket: durable, flexible, and discreet.
