Antennas : 2M
  • Squarooka Antenna - squared bazooka for 2 meters band - Sort of similar to the one of the 6m omni. Instead of using twin-lead, this design makes use of a more or less regular double bazooka antenna (coaxial dipole). Your attention shall be drawn to the available standart literature, such as Rothammel. In order to "compute" the dimension, Karl Rothammel mentioned that the total length of the dipole shall be 95% of the free-space wavelength. The short-circuit bridges (closing the folded dipole) are to be placed at a distance-fraction being equal to the velocity factor of the coax cable used, which will be 66% using RG-58 or RG174.

Antennas : Dipole
  • Folded dipole antennas: terminated vs un-terminated - As the name suggests, it is simply a dipole with the tips folded towards each other. In this case, a full-wave dipole. The span of a standard folded dipole is aprox 0,5 lambda. In this article the author investigate on differences between un-terminated vs terminated folded dipole antennas.
