Subject: Pietenpol-List: Stearman install of flexible AAE antennahttp://www.stearman.net/?p=1035Looks like this could very easily be done on a Piet too against oneof the diagonals in the fuselage. You wouldn't even need the plywoodbacking they use to stiffen the antenna. The antenna itself is flexible so they coil it up into a circle to ship it butit expands flat. Mine is strung in the shape of an umbrella or upside down U behind my pilot seatinside the fuselage and below the baggage/hatbox area.

Interesting. I've made folded dipoles out of old twin lead feedline, like whatwas used on old TV antennas. Are these elements some sort of metal, or are theywire, or? I can't really tell from the photo... perhaps they are just flatmetallic strips? Generally speaking, bending the antenna elements (in the caseof a dipole) is poor practice because it has a negative effect on the radiationpattern and could also effect the impedance. I know, I know... too muchinformation, but it's true. Not that it's a BAD thing, but again, to a radioguy, it certainly isn't a good thing.Hey, if it works, that's what counts. As far as the overall construction of theseold low and slow airplanes, the radio system is certainly way down the listof items to fret over. Again, it's just something that some of us look at differentlyand would enjoy tinkering with.--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Plans for a simple antenna that should work.

Here's another one worth trying. It's designed for our radios and our frequenciesalready. It's another one we could make a batch of at Brodhead.http://chrusion.com/BJ7/InvVeeAntenna4ULs.pdfToolsRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
