Hello Rag & Fellow Topbanders.
The dimensions you found on DX zone should be OK and could be longer. For
example,
I have successfully used pennants with 14 feet vertical dimension and 29
feet long/horizontal dimention. The feed point with the transformer is in
the middle of the 14 foot vertical wire.
These dimensions will also work on 40 meters and maybe on 30 meters.
I have also modeled but not built larger pennants, 20 x 40 feet or 6 x 12
meters. EZNEC 4 shows these dimensions will work on 40 meters but has front
to back problems on the 30 meter band.
