Topband: New 160M high performance receiving antenna at W3LPL

[Tom W8JI]

The "Wullenwever" antenna was never a low-noise high performance antenna. It 
was simply a system designed to find direction over a very wide frequency 
range. The multitude of elements increased bandwidth, but the physical width 
in wavelengths is the primary determinant of directivity.

If we had a 350-foot width array, it would work essentially the same on 160 
meters with four elements as with 400 elements. The extra elements primarily 
extend the cutoff upwards in frequency and allow more direction choices.

Of course we all know some antennas break rules, and directivity is more 
than size in wavelengths. Some CB antennas use 8 elements on a 36-foot boom 
and have a power multiplication of 20.5 dB or 115 times, and have 28 dB of 
audio gain.

If we could just build one of those for 160!!
