Build an HF Ham Radio Dipole Antenna

 

It is easy to build, construct and erect a wire dipole antenna for the HF band 40 metres,  using a few simple components at a minimal cost and get great results. 

 

•  Dipole arm length (inverted V 120 °) in meters: 9.993
•  Frequency in KHz: 7100
  

•  ..the dipole resonates very well at 21.5 Mhz
