Radio for Preparedness 101: HF Antennas

I'll apologize in advance.....HF antennas can be complicated. You'd think a piece of wire would be simple, but it isn't. Today we'll be looking at various types of antennas, and we'll discuss what you might want to consider for your HF radio kit. We'll discuss resonant vs. non-resonant antennas, as well as bandwidth. We'll talk about mono-band vs. multi-band antennas. We'll also discuss whether you should buy an antenna, or consider building it yourself. Other things discussed will be height above ground, how to get the antenna in the air, orientation and polarization, directional vs. omni-directional antennas, coax, and power considerations. Finally we'll head into the shack to discuss antenna analyzers, SWR, impedance, and length calculations. There's a LOT to learn about HF antennas, and this is just a basic primer. If you have any questions, feel free to leave them in the comments below. As always, thanks for watching, and 73! Antenna Length Calculator: https://www.westmountainradio.com/ant...
