Solving the Mystery of a Shorter Antenna - End Effect & Velocity Factor
Are you wondering why your antenna is shorter than it should be? In this video, we'll explore the concepts of end effect, velocity factor, and height above ground and how these affect the electrical length of an antenna.
First, we'll explain how end-effect shortens the electrical length of your antenna and how it can be compensated by adjusting the length of the radiator. We'll also discuss how velocity factor affects the propagation speed of electromagnetic waves and how it can vary depending on the type of coating or material.
Then, we'll dive into why height above ground affects the tune of an antenna.
Whether you're a beginner or an experienced ham radio operator, this video will provide valuable insights why adjustiung your antenna can be slightlly "weird" sometimes! Stay tuned and let's dive into the world of antennas!
