Yes, the Vivaldi antenna is absolutely used in amateur radio, though you will primarily find it in microwave, UHF, and wideband SDR (Software Defined Radio) applications rather than
How long-distance flights communicate with Air Traffic Control (ATC) depends entirely on where the aircraft is. Because radio waves have physical limitations, the aviation industry uses a layered
The J-Pole antenna is a popular, practical, and highly efficient omnidirectional antenna. At its core, it is an end-fed half-wave dipole that uses a clever impedance-matching trick to
My amateur radio friends VU24DX and VU2CPL are using automated lightning detection and antenna disconnection systems. An automated lightning detection and antenna disconnection system is a critical line
The random wire antenna is considered a powerhouse for portable operations—like Parks on the Air (POTA), Summits on the Air (SOTA), or general field deployments—because it perfectly balances
The Carolina Windom is a popular, multi-band wire antenna that takes the traditional Off-Center Fed Dipole (OCFD) and gives it a specific twist: it intentionally uses a section
In satellite communications, the terms LNA, LNB, LNC, and LND represent different configurations of the front-end RF (Radio Frequency) hardware mounted directly at the focal point of a
At its core, antenna polarization refers to the physical orientation of the radio wave’s electric field as it travels through space. When an alternating current is applied to
A Delta Loop is one of the most effective and forgiving multi-band wire antennas you can build. While a standard half-wave dipole is notoriously stubborn when you try
Duct propagation, often referred to as tropospheric ducting, is a fascinating atmospheric phenomenon that allows VHF, UHF, and microwave radio signals to travel vastly beyond their normal line-of-sight
