Ground wave propagation plays a crucial role in radio communications, especially at lower frequencies. It refers to radio signals that travel along the surface of the Earth rather than reflecting…
When choosing Indoor vs. Outdoor Antennas, it is a critical decision for amateur radio operators. Each type offers unique advantages and limitations, depending on location, operating style, and regulatory restrictions.…
The Radioddity RA-UV713 Antenna Kit provides handheld radio users with a practical way to improve their signal performance. This 20-inch dual-band antenna is designed for both VHF and UHF frequencies,…
NVIS antennas (near Vertical Incidence Skywave), describes a method of radio communication that focuses signals nearly straight up toward the ionosphere. The signals then reflect back down over a wide…
Parks on the Air (POTA) has become one of the most exciting ways to enjoy amateur radio. picking the best POTA antennas that balance performance, weight, and ease of setup.…
Understanding Resistance in Wire Antennas In wire antennas, Resistance and Reactance are importance factors to consider. Resistance refers to the part of impedance that dissipates energy as heat or radiates…
VHF/UHF handheld antennas play a critical role in the performance of VHF and UHF radios. These compact antennas must efficiently radiate and receive RF energy while operating without a traditional…
VHF/UHF Antenna Placement in EV (electric vehicles) presents unique challenges. Unlike traditional gas-powered vehicles, installing transceivers in EVs generate more internal electrical noise, have limited metallic body panels, and carry…
Baluns, ununs, and chokes play a critical role in antenna systems, particularly when ensuring efficient power transfer and minimizing interference. Though simple in appearance, these components influence everything from feedline…
