Thanks for the document on this antenna. I was going to try resizing
the 2m Lindenblad design of Tony's but this will be a snap for me. I
have 1/8-inch rod elements from an old Cushcraft yagi that
disintegrated long ago and have some 1/2-inch sched-40 aluminum pipe
(7/8 inch OD) that will work fine for the vertical. I can get the
PVC from my local building supply. Only need to order ferrites from
Mouser. Since I will place a 432 preamp at the antenna a short run
of RG-58 or mini-8 will suffice. I probably will make some variation
in the materials used. I did that on the 2m Lindenblad (not assembled, yet).
