Measuring and Tuning Trap Using the NanoVNA
Hello to all multi-band antenna builders! Today I will show you how to easily and accurately measure and tune traps using the indispensable NanoVNA. The trap is the heart of a multi-band antenna, and its proper tuning is essential to the entire operation. I will share my method for getting the ideal parameters and achieving excellent SWR on all bands.
What you will see in the video:
I will show you what a trap is and how it works in an antenna.
We will prepare the trap for measurements together.
I will guide you through the step-by-step tuning of the trap using the NanoVNA.
We will measure the resonant frequency and Q of the trap.
Practical tips for achieving the best results.
