I wrapped about 1710m of 0.50 mm diametrp painted wire in a one meter octoloop

Loop 4 m octagonal perimeter 14 MHz
On my list of new antennas to experiment with is a magnetic loop with a broadband current amplifier in lieu of the usual resonating components

Antenne a telaio
Framed antennas We all had a disappointment when we tried to connect one of those vintage frame antennas to a home radio

Draw a 36-inch diameter circle on your garage floor. Lay a yard stick across the circle with one edge on the center


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

A simple SWR Meter is to be used at HF

A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
