Topband: Top band portable antenna.

[k8gg at voyager.net]

Iain, Etc.,

Some years ago I operated 160 and 80 from PJ4-Bonaire.  W8UVZ, KD9SV and I
used a single pennant antenna aimed at Europe with good results.  Bottom
about 6 feet above ground, 14 feet of vertical wire with the 910 ohm load
resistor in the middle and two sloping wires, 30 feet long each to the
feed point with an 18:1 transformer for 50 ohm coax to the RX port on the
transceiver.

These antennas can be "redirected" by moving the feed point which is the
"back end", so one could start out looking NE for Europe and then NW for
Asia and W or SW for Oceania before sunrise.  It all depends what you have
to tie off to on the back end.

We found that trees, and masts, both metallic and non-metallic make good
front supports as long as the vertical wire is about 3 feet or 1 meter
away from the mast.

I hope this helps.  73, GL,

George, K8GG
