From: "Mark Langford" Date: Sat, 19 Feb 2000 18:53:42 -0600 X-Message-Number: 1 AntennaHeads, I guess either the server's acting up again, or nobody has anything to say. Well, I'm installing radio and transponder (among other things) and started wondering about interference. I'm violating the instructions to ALL of the devices, which all state something like "don't locate this thing anywhere near any other electronic device or it's antenna". Well, in something the size of a KR, I'm lucky not to have them all bolted together! My antenna is the copper foil tape variety mounted to the leading edge of the vertical stabilizer. The antenna coax runs down the left upper longeron, right by the pilot's seat up to the panel, and then to the radio. That's as far as I can get it from everything else. All other wiring is located on the other side of the fuselage (trim tab and ELT). The strobes are in the wing tips, and the shielded cable for them enters at the stub wings, and I'm thinking about putting the power supply for them on the top shelf of the firewall. I could put it under the seat, but that would be right next to the fuel pump, which makes me a little nervous (BOOM!). The transponder antenna (about 4" tall) is probably going right next to the strobe p/s up on the firewall, mounted between the top and bottom shelves of the firewall. I would think it's better to put that antenna closer to the radio than the comm antenna, although it's awfully close to me. Has anybody had experience with interference between these devices, and if so, what kind, how were yours located, and how did you solve it? One obvious answer is to wire it all up and see what kind of noises I get in the system, but I've got to start somewhere. I may just start soldering wires together tomorrow...

Just dont put that thing next to parts of your body that you might need at a later date for reproduction. ;o) -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ --- END OF DIGEST --- You are currently subscribed to kr-net as: johnbou@ipinc.net To unsubscribe send a blank email to leave-kr-net-110995W@telelists.com
