DIY Antennas, QRP, SDR & Ham Radio Projects from VU3DXR
This tag features technical guides on building and tuning wideband HF antennas like the T2FD and Terminated Folded Dipole variations. Learn about the critical role of non-inductive resistors and 16:1 or 9:1 baluns in achieving low SWR across multiple bands without a tuner, perfect for stealthy or space-constrained amateur radio setups.
This article explains a terminated mini loop antenna designed for small spaces, combining loop geometry with resistive termination to achieve directional reception and reduced noise. It covers construction using wire, a terminating resistor, and a matching transformer, delivering wideband HF performance without a tuner for compact installations.
Terminated End Fed V Antenna (TEFV) – It Is a travelling wave antenna, which has a constant current distribution along its length.
