Martin, Carl and Bruce, many thanks for the graphics and suggestions.
I think I can install one temporally to compare the results of a 900 feet
against 600 feet.
Many thanks to all for sharing opinion and experiencies. Eddy, LU2DKT

Please let us know how that works, Carl. I'd love to experiment with a
Slinky.
If brass Slinkys aren't available anymore, then we could wind one from some

about "why so many", probably I missed the point that 3 or 4 db in directivity
loss because of deeps is much more important that I figured out and that could
make a difference in a QSO or not.

Come on Carl! You're just being provocative. Someone may take that

Close-wind it first, then stretch it to the desired (?) pitch.
73,
Next year Im planning to try a couple of Slinky Beverages again in
order to get a 2-3 wave electrical equivalent for particular paths
and narrow the beamwidth to get rid of EU "noise".

The hams with Beverages that cover more than four directions likely have
Beverages with a 3 dB beamwidth narrower than 90 degrees, such as:
1. A single Bev 1.5 or 2 wavelengths long
2. Two of them pointing the same direction and phased together.
