It can be installed  as inverted L, Horizontal, Vertical or Slopper, so it present many advantages during the setup in portable operations.

A typical instalation for portable operations is to use a mast or rod and mount it as inverted “L”.

Thanks to its easy installation and light weight, it is an ideal antenna for portable operations as SOTA, Field Day, etc.
