Many hams have questions like these:
- How do I know if my dipole/vertical antenna is too short or too long?
- What is its resonance frequency?
- How does putting a balun in front of the antenna change it?
- Why do some antennas at some frequencies don’t tune properly?
- How much loss do I introduce by inserting anything like a balun in front of the antenna?
- How do I measure the value of a capacitor or inductor?
You can do these and more with a nano VNA (and you might wonder what do the initials VNA stand for and what do the words mean). Come to the nano VNA workshop on Saturday October 4, 2025 at 10am at the W2ZQ shack, learn these and more.
