Next, a directional antenna (a planar array antenna with a gain of 15 dBi for 2.4 …
2.5 GHz) was tested. The SWR is only good at very ends of this frequency range, mostly
having very high values (more then 2). This indicates a poor quality of the antenna and/
or the cable.
In the third experiment (see the screenshot below), yet another antenna was connected
to the tester: a 17 dBi, parabolic reflector and a log-periodic feed.
It looks like this antenna has never been tested at the factory: the SWR curve looks
fully random.
