Wire skelleton structure with 8 vertical wires.
Dimensions for a bandwith
starting from 7MHz
Standard scheme for cabel connection to the wires and metal center mast.
For 80m and 160m I use this vertical with a ground loading coil.
7 MHz - Dimensions, only the center mast is from fibre glass.
Each single pole aerial lives only by its mirroring ground.
The substitution on the flat roof is my 12m x 50m wire net.
Vertical radiation pattern
in ratio of antenna height
to working frequency.
