Received a couple of inquiries for data on the 7 el 40m LP wire beam we
have been using for FD (N6AW 3A).  The original article is in Ham Radio,
April 1980, pages 26-40, by W4AEO and W6PYK.

Here is the data (dimensions in ft):

Element Length  Spacing
1       69.6    0.0             (Reflector end)
2       66.0    25.2
3       62.7    23.9
4       59.6    22.7
5       56.6    21.6
6       53.7    20.5
7       51.0    19.5            (Director end)

Open wire feedpoint starts at element 7.  All elements are connected
with open wire feedline, which is reversed between adjacent elements.
