From: Timothy Willis Mark, Thanks very much for your reply. Despite "not wanting to pound keys," you gave me a lot of rich info in text form, all good stuff. My first reaction is to state that your dipole is more or less what I had in mind for a wing installation, but as Jack P. apparently does, I'd likely experience that polarity problem. I think the same would be true in placing the dipole in the fuze behind the pilot, running it fore and aft. You would know more about that. If we can agree on that, then it is all a choice of placement of VERTICAL antennas. I like the idea of making something, so it may well be something like Mike Cuy's inverted quarter lambda with ground plane. While I am a long way from needing a radio, now is the time to install anything inside the fuze. And Ii need to consider the location for that pesky ELT stuff. There could be more stuff than I like behind the pilot seat. I have saved all this antenna discussion, pix and vendors, and will chew on it all for awhile. I'll also send to my RF buddy. You and he could have discussions of great mutual joy, all far over my head. I love your big array antenna, and he will, too. Before I do anything I will call you. Thanks, Tim in central TX ________________________________ Message 3 _____________________________________ Time: 08:59:24 AM PST US Subject: Pietenpol-List: Re: antennas-- reply to Mark C. From: "K5YAC" Yeah, feel free to call Tim. I think I gave you my card, but if not my info is in the Piet Builder's list that Jack Textor maintains and distributes. If you don't have it, let me know. On the dipole... while not my first choice in an antenna, I can't say that it wouldn't work well in one airplane or another. While most of our builds are similar (cables, fittings, etc.), there are variables that could (and probably do) have and effect on these things. That is why I can't give a definitive answer on what would absolutely work best for everyone... my position is simply a reasonable starting place for someone who wishes to construct their own antenna based on... 1. The desired pattern (omnidirectional, as in a vertical). 2. Ease of construction. 3. Simple to tune. 4. Perhaps most importantly... good engineering practices. It's just another thing to learn along the way. I find radio fascinating... even in these days of computers and the Internet... no, ESPECIALLY in these days of computers and the Internet. Some might choose to dig in and learn something else, like constructing and drilling wheel hubs... not me. I'll leave that to someone that already has it figured out... thank you Ken Perkins! Yes, I'm still excited about the fact that wheels are in the very near future.
