One of the biggest myths in amateur radio has nothing to do with antennas... it's the coax connecting your radio to them.

Does coax really have to be 18 feet long? Can changing the length of your feedline lower your SWR? What exactly is velocity factor, and why does everyone seem to have a different answer?

This week on Brew & Activate, we're diving into another ham radio rabbit hole to separate physics from folklore. We'll explain velocity factor in plain English, explore why coax behaves the way it does, and connect the dots between transmission lines, SWR, resonance, impedance, and real-world station performance.

Whether you're building a portable POTA station, setting up your first HF antenna, or just trying to understand why your analyzer says one thing and your radio says another, this episode will hel ...
