QFH-Antenna-Kit for L-band (1.6 – 1.7 GHz)

Matthias, DD1US, April 28 th 2021, Rev 1.0 For some measurements at antenna feeds for the L-band weather satellite downlinks, I needed a test antenna. As I like QFH antennas and found an offer on Ebay for less than 7 Euros including shipping from China, I decided to try it. The QFH antenna kit is advertised as: Feature: - High quality and professional - Not easy to break, stable performance and long service life - Interface: SMA female - PCB size: about 80×22.5mm - Weight: about 10g Package: - 1x Kit 1.6GHz 1.7GHz L-Band QFH antenna

As can be seen on the picture above the kit consists of a small PCB, an SMA-Jack and a piece of silver coated copper wire with a diameter of 1.2mm. After some searching on the Internet I found out that the design was originally posted by “sam210723” at OSH-Park.
