4 Aligment for best performance
Out of the box (without any special alignments) the sweetspot of the antenna is
somewhere within the 11m band (e.g. 26.490Mhz) and it has already a acceptable
SWR.within the 11m band. As you know the SWR is depending on various parameters
such as the way the antenna cable is routed or bend, the humidity and a few more
environmental aspects and of course the frequency used. So, for 11m HF, even a value
of about 3 is not top notch, but acceptable. However, the antenna may be aligned for
even better SWR.
In order to align the antenna for best performance you will need either an antenna
analyzer or a SWR meter. The measuring device should be capable of measuring SWR
within the 11m (27MHz) band.
