Antenna modeling discussions about What happens if… a dipole is bent horizontally, laterally, vertically. Zig-zag, meander, catenary curve. Effect of sag, elevation, radials. OCF off-center feed, harmonics. Includes 4NEC2 antenna models for each study.
The HB9CV is a well known two element antenna of a directional beam type with a forward gain of 4 to 5 dBd. This one is for two metres but it can be scaled, from the dimensions in the diagram, for other bands I have also made them for four and six metres
