Currently my low-bands antenna consists of a sloping inverted vee. The
center insulator is attached at the chimney support on the back of the house
at about 27 feet above ground and is fed with open-wire line, which drops
straight down into the basement shack. Each leg of the dipole is 75 feet
long with 60 feet between the center insulator and a 12 foot 2x4 at the two
fence corners. The last 15 feet of each leg then makes a 90 degree bend and
is fastened to the fence top at five feet above ground.

The antenna in its current configuration seems to put out a good signal,
about what one would expect for an antenna at this height. I have been
thinking about adding a 40 foot self-supporting fiberglass pole at the
center of the back yard fence. This would allow me to lengthen each leg by
about 22 feet, and the two legs could be connected to an insulator mounted
on the flagpole. In this configuration the ends of the legs would be
elevated to an height of 40 feet. I could also remove the insulator, and by
joining the two ends I would have a loop antenna with total length of about
194 feet.

Before expending money and time on this antenna modification, I would be
interested in comments about what, if anything, I might expect in improved
antenna performance.
