Small Garden Multi Band HF Antenna 80m / 40m / 30m / 20m / 17m /15m / 12m

This HF multi band antenna for small gardens that works well on 80 meters Main bands (@~50 ohm) are 80m / 40m / 30m / 20 / 17m / 15m / 12m

A 14 meters ( 46 ft ) multi band antenna for small gardens that works well on 80 meters Main bands (@~50 ohm) are 80m / 40m / 20/ 30m / 17m / 15m / 12m


Evolving from a simple end-fed Marconi for 80m, this antenna design was created by Mike G7FEK (reproduced with consent ).The idea was to use the opposing harmonic
relationships of two ¼ wave elements so that they could be fed on odd harmonics without mutual coupling. This principle has been
used with nested dipole antennas and other specialist multi-band antennas such as the Cobweb, but because of interaction and coupling issues, it’s rarely implemented on end fed wire antennas. With this version of the antenna, interaction between elements
and top resonance have been turned to our advantage allowing for excellent multi-band working, while maintaining a useful radiation pattern and efficiency on almost all Amateur Radio bands.
Low radiation angle of 30 to 40 degrees on 80m .Low VSWR is achievable on most bands and, with careful installation, up to four bands can be used without ATU. Radiation resistance is in the range 25 to 200 ohms on all bands, ensuring high radiation efficiency, even with moderate earthing arrangements. Unlike the Windom or G5RV, the fundamental bands can be resonated independently.
