My Antenna Zepp, Double Zepp, or Dipole
Two independant wires separated by insulated spacers and usually having an impedance in the range of 400 to 600 Ohms
Reversible Parallel Slot Antenna
Low Profile Paired Verticals for HF a couple of years back and I decided to build one for the low end of 20 Meters
Simple wire dipoles and verticals
You can achieve the bang of a horizontal dipole at a one half wavelength height required for low angle DX performance
Sky-Hook for the Antenna Wire, DL6IP
The receiving antenna was a 122m long wire fixed to a Kluever Kite that served as a sky-hook. This law of physics is still true today

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
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
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
