Vector Network Analyzer ( VNA) - 4 - Testing a 'Lora' antenna

With my Vector Network Analyzer i decided to test a LoRa antenna that i had still in a part box as i was never successful in using it.
In my region the Frequency for Lora is 868MHz (and so is my Lora hardware).
However using  my VNA i found out relative easy that this antenna would be more successful in the 433 MHz region and would not be very useful at 868 MHz ! 

 VNA measurement
This explained why i never had any good results using this antenna !
I expect this antenna was listed a LoRa antenna when i did buy it, however not for my region.
