✅Gizont 40cm 915mHz VNA sweep

The Gizont 167mm is a very good (slightly wider band) antenna. This is likely an impedance matched 5/8-wave or a colinear (multi-element). They say it is a 10 dBi but is is more likely a 5dBi by lenght...
The bigger Gizont 40cm
-24dB of return loss is pretty good
It is much wider band the the 167cm, it is a good one.

(Calibrated for a span of 100MHz, but displays a span of 200MHz, so good enough)
