The T2FD (Terminated Tilted Folded Dipole), often just called a Terminated Folded Dipole, is a broadband wire antenna originally developed by the US Navy in the 1940s. In
Yesterday night there was a Western pass of International Space Station in my region starting at 2124 IST (UTC+530). I had kept my Moxon VHF/UHF Yagi pointed in
The Radioberry is an open-source, full-duplex High Frequency (HF) Software Defined Radio (SDR) transceiver designed to operate as a Raspberry Pi HAT (Hardware Attached on Top). Originally developed
A “Long John” antenna is a highly directional Yagi-Uda (beam) antenna characterized by an exceptionally long boom. Though originally an antenna from a specific manufacturer, the term is
At first glance, Amplitude Modulation (AM) seems like an archaic choice for modern aviation, especially given Frequency Modulation’s (FM) superior noise immunity. However, the aviation industry sticks to
These seedlings are growing wildly in search of light, indicating positive phototropism. My friend told me that he had seen Okra seedling growing wildly when magnets were placed
What makes a Log-Periodic Dipole Array (LPDA) special is its ability to maintain consistent electrical characteristics—impedance, VSWR, radiation pattern, and forward gain—over an exceptionally wide range of frequencies.
A phased array antenna uses two or more radiating elements driven by the same transmitter. By carefully controlling the timing (phase) of the RF signal reaching each element,
