I forgot to add that these are patterned after Tony, AA2TX, designs (UHF version is in Feb. 2010 QST). My variation was to use pvc sched-40 plastic pipe (white).
The preamp is one of the older DEMI designs that uses a mgf-1302 GasFet with about 0.7 dBNF. I see about one s-unit of noise when I turn it on. There is 4-feet of RG-58 to the UHF Lindy and 60-feet to the FT-847 from the preamp. The VHF Lindy has no preamp and is fed with 60-feet of RG-213.
The VHF Lindy brings up repeaters 70-miles away with 50w, and the UHF Lindy hears repeaters that far away. So actually can make a nice general purpose antenna.

Just a note that I copied HO-68 beacon yesterday on my new Lindenblad antennas. I have updated the webpage: http://www.kl7uw.com/LBant.htm
I am only running mode-VU with the "Lindys" because the UHF antenna has a preamp and the VHF one does not.
My directional satellite array is not quite QRV; needs cables connected in shack. They have full capability for modes; VU, UV, US, VS, LU, LS So I will not be on AO-7, VO-52, or FO-29 quite yet.
