Topband: 160 vertical, radials and beverages

[John Kaufmann]

I think you will find that using the Beverages as
elevated radials is not going to work well.  One
requirement of elevated radials is they should not
produce much far field radiation.  Otherwise the
pattern gets distorted by this radiation.  When the
radials get really long, it's hard to maintain the
electrical symmetry and balance between the radials
which is needed to prevent radiation.  For this reason,
some people advocate short elevated radials, like 1/8
wave long, where it's easier to maintain electrical
symmetry.  You won't run into these problems with
ground-mounted radials.

Also, keep the Beverages away from your vertical,
preferably one wavelength or more if you have the room.
They do couple well to verticals as people on this
reflector will attest.
