This is interesting. I remember reading where the G5RV originated as
a gain dipole for 20 meters. I hadn't looked at it as a 1.5wl dipole.
I have always used 1.5wl dipoles for 15 (40 meters) and had low SWR on
the 15 meter band without a matching network. Am i missing something
or is the coax stealing enough power to reduce the SWR?


Bingo! Your 15m SWR at the 40m dipole feedpoint is probably
above 2:1. Feedline losses both ways probably reduce it to
a value tolerated by your transmitter. If you replace the
coax with an integer multiple of 15m halfwavelengths of
ladder-line to reduce losses, your transmitter may object.

I have inadvertently stepped upon an unpublished article with
my posting. I apologize and will bow out.
