[amsat-bb] Re: New Lindy's QRV
Well, each to their own, obviously. I've worked the birds using the Arrow antenna and an HT, and that works okay, but I secretly dream about working them from the shack instead of sitting in the back yard, and big pointable antennas are a no-no in my neighborhood. I can get away with something more discrete, like the Lindy. 73, Dave NK0E -- Clint wrote: I read that article, and when I got to the last of it and he mentioned that he was using a pre-amp for working the FM birds, I wondered out loud: "Why???" We're working '27, '50, and '51 with HTs and meager antenna improvements. Better yet, build a tape measure Yagi - you can realize great gain with about six bucks of parts. Note that I haven't mentioned, "Buy a pre-amp" anywhere. I was considering building one of those antennas mentioned in QST last month - until I read that he was using a pre-amp. I'll just stick with what works for me ... home-brew or commercial Yagis ... a log periodic every now and then ... and no pre-amp anywhere. Clint, K6LCS ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: New Lindy's QRV
Question for anyone out there: I just built the parasitic Lindy from the Feb 2010 QST. What kind of performance (on receive) should I expect from it during, say, an AO-51 pass (max EL 83 deg)? I had my Kenwood TH-F6a HT connected directly to it (only a few feet of RG-8X coax to the antenna) with no preamp, and I only had good copy for a moment here and there. Just wondering if I need a preamp or if I need to be suspicious of my construction. tnx & 73, Dave NK0E - Edward Cole wrote: 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. 73, Ed ___ Sent via amsat...@amsat.org.
