Ham and Shortwave Radio
Articles about antennas-
Shortwave listening antennas are used to receive radio signals in the shortwave radio frequency range, which lies between 3 and 30 MHz. These antennas are typically designed to be highly sensitive and directional, in order to maximize the strength of the received signal. Some common types of shortwave listening antennas include loop antennas, which consist of a loop of wire or tubing that is oriented in a circle or oval shape; long-wire antennas, which consist of a long wire suspended horizontally or vertically; and beam antennas, which consist of multiple elements arranged in a specific pattern to provide directional gain. Shortwave listening antennas can be purchased commercially, or they can be built by the user.
Here is a lost-cost solution to a common problem for shortwave listeners and ham radio operators. How to share one antenna among several radios (for listening only). A shortwave antenna splitter is needed. You can find HF splitters online, but they are not cheap. Let me show you how to save a few dollars. Note: … Read more
I use a Par End-Fedz antenna at my QTH, in particular, the EF-20. Par Electronics calls these antennas ‘dipoles’. They are nothing of the sort. Just because an antenna is a half-wavelength long, does not make it a dipole. Here’s what they say- “The Par End-Fedz are a full length half wave dipoles, but with … Read more
New video: Earchi.org S9 Antenna rocks! The earchi.org antenna is a type of antenna designed for amateur radio use. It is also known as the End-Fed Half-Wave (EFHW) antenna, and it was first developed by Steve Yates (AA5TB) in the early 2000s. The earchi.org antenna is a simple and lightweight antenna that can be easily … Read more
The ELAD ASA-15 is an antenna splitter designed for use in radio communication systems. It allows multiple radio receivers to share a single antenna without interfering with each other or degrading the quality of the received signals. The ASA-15 is designed to work with antennas that have a coaxial feedline, and it has four output … Read more
Now that I have my WiNRADiO G31 SDR up and running, my next concern is getting a decent antenna connected to it. I currently have a random length of wire connected to it, which is about 25 feet long. It’s not that high up either. The roof of my house is higher, so it’s not … Read more
