I have been paying attention to APjohn's thread regarding a stable single liner.

I was thinking about how to use a single line kite to hold an HF radio antenna.  Anyone have any experience with this?

I'd talk to people who do KAP - I'd guess they'd know what a good stable lifting kite was.

well...there is a kite called a Marconi.............and it is named after radio pioneer Marconi who *iirc* was the first to do cross Atlantic transmissions....and he made his own style of lifting kite for his antenna....and that style is called a Marconi.....(Premier makes modified one as their Canard and a BMK 61/49 is a modified one as well)

a Rok or a Genki or a flowform would works just fine....

Thief:  Dead on balls accurate, and smack on point.  Here's the first link I found with my limited Google-fu:

kewl!!!!
to be very honest here i have yet to see a Marconi kite that is actually stable on its own.....whether it is the build quality of the ones i have seen or the specific design I do not know...but i always have seen them start wandering and then crash hard....

personally i would shoot for a rok or a flowform.......simple simple kites.....make life easy!

good winds!

I have always flown my Marconi as an active SLK.  Controlling steering by controlling line tension.  Alas, this Saturday I found a decided weakness in the design of the nose on my GKPI Marconi.  Two dacron sections joined by a weaker nylon panel at the nose, guess where the fabric lets go? Sigh.... time for some TLC.

To be fair, it has survived a lot of high wind sessions without a complaint.  This has more to do with addressing a common stress point.

+1 on the FlowForm, Rok, Genki, and possibly an upsized Fled (Brookes Leffler).

The World War II M-357-A box kite (foldable, aluminum frame) was supposedly used by downed pilots. The "line" for the kite was a wire used as a radio antenna. It is not too stable in lower winds, but has 2 tow point settings, with the upper setting good to 35 mph IIRC.  Huh

Interestingly the kite that bears Marconi's name is not the kite he used for his radio experiments. That was a modified Rokkako type http://www.cradleofaviation.org/exhibits/dream_of_wings/marconi/ - but that best breezes site is great, I'll be checking that out.

Another supposedly stable platform is the Dopero (double pearson roller) and good in lighter winds, again Gomberg has a version, I have no experience with it though to confirm it is stable.

Here's a couple (well one, forgot some of the others sell kites too) more good resources on KAP, that is a good direction to look for what you want,

http://www.arch.ced.berkeley.edu/kap/kaptoc.html

google it, it's a pretty active group.
