: Beverages 2 basic questions
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
#14 or #12 solid copper wire using a long piece of plastic pipe as a form.
Close-wind it first, then stretch

feeling is that performance could not be duplicated by various other
loading methods. If somebody wants to make real world comparisons it might
be beneficial.

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

Eduardo - your arrangement should work well, especially if you place the
main lobe into areas of interest and the nulls are into regions of no
activity (or noise sources). It is a good general setup.

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.
See
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.

Close-wind it first, then stretch it to the desired (?) pitch.

Hi Bob,
You have the right idea from the standpoint that 1500 feet of wire in a
100-foot linear spatial distance is

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.
Keep in mind that
Dear Topbanders, I am planning my next move with the beverages and I would like
to hear your opinions about 2 areas.
Looking at the pattern response for beverages in for example ON4UN book, I
found that If I install 4 x 600 feet or 5 x 900 feet beverages, I should cover
