We start by explaining how antennas work, focusing on how they direct and reflect signals to gain strength without boosting the signal itself. We use a Nano VNA to measure the SWR and peak frequencies of these antennas, revealing their real-world performance. Through practical tests using Heltec V3 devices to measure RSSI changes, we compare the antennas' effectiveness in improving signal strength. Despite some tuning challenges, our results align with manufacturers' claims, highlighting the importance of choosing the right antenna for your needs, whether for connecting to a mesh network or simply enhancing your signal. This video serves as a straightforward guide for anyone looking to understand and optimize their antenna setup.
