Drew,

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).

73, Ed - KL7UW
