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.
73, Kevin N6ER
