The main function of the standard firmware is to measure antenna performance.
Rugged and durable, effectively shields electromagnetic interference and ensures measurement accuracy.
With an independent 2.8-inch LCD display, it is a DIY product that provides perfect vector network measurement functions.
Small and portable, flexible and convenient operation.
Easy to use, this project aims to provide a small but useful tool for RF enthusiasts.
