A repeater is an automated radio station, usually situated at a high elevation, designed to receive a signal and simultaneously retransmit it at a higher power. Its primary
In the antenna world, the terms “radials” and “counterpoise” are often used interchangeably because they both serve the exact same electrical purpose: providing a return path for RF
Neither antenna is universally “better” — the right choice depends entirely on your available physical space, the number of tall supports you have, and your operating goals (DX
Standing Wave Ratio (SWR) is essentially the report card for how well your transmitter, feedline, and antenna system are matched. In amateur radio, achieving a good SWR is
EIRP (Effective Isotropic Radiated Power) is the total power that a theoretical, perfect omnidirectional antenna (an “isotropic” radiator) would need to emit in all directions to match the
Effective antenna aperture (often called effective area and denoted as Ae) is a measure of how successfully an antenna captures radio frequency (RF) energy from a passing electromagnetic
Live Streaming Trial of ARISS (Cross-Band Repeater on Amateur Radio on International Space Station) Pass, followed by Hambel Belgaum Net from 0708 IST, 7 June 2026 (4:27). Initial
The Loop on Ground (LoG), popularized by KK5JY, is an exceptional receive-only antenna for the lower HF bands (particularly 160m, 80m, and 40m). It seems counterintuitive to lay
Designed in the 1970s by G2BCX, the Slim Jim (Slim J-Integrated Matching) is essentially a vertically polarized, end-fed folded dipole. It is a favorite among amateur radio operators
While both the standard horizontal dipole and the inverted V are half-wave wire antennas, physically dropping the ends to form the “V” shape changes how the RF energy
