Abstract: A broadband bow-tie shaped HF antenna placed above a conducting ground plane with a very low height (around 1 meter) is presented in this paper. Through a simple analysis of a horizontal ...

It had always seemed logical to the writer that when ferrite rods first appeared in broadcast receivers, the technique ought to be usable for transmtssion antennas.

To understand that complexity, just imagine a surface vessel and a submarine side by side and look at the antennas embarked on both of them. The surface vessel gets its radiocommunication antennas ...

Modern ham radio operators often face restrictions on antennas. This has made small antennas more popular, despite some limitations. [Tech Minds] reviews the GA-450 indoor active HF loop antenna and ...
