[Antennas] " G5RV " TYPE ANTENNA / "CUSHCRAFT MA5V"ANTENNA QUESTIONS

[Pat W]

The G5RV optimum performance occurs when the coax
length is zero!

 Contrary to some misleading opinions, there is NO
magic coax length, other than zero.  Beware that the
longer the coax, the greater is the loss and, the lower
the is SWR!(If the coax is long enough, the SWR will be
1:1 from DC to daylight).  SO, some think that because
the SWR is reasonable on some bands the system is
efficient when it's not.  The only way to determine the
tuning range is to use multiples of 1/2 wavelength of
ladder line(or other open wire line).
