Martin,
Must be difficult not knowing for sure whether what you are sending up will come back to you or not. :( , I am happy that mine comes back so far ;)
But that turret hardware will do the job if yours dosn't . :p

The tracking and recovery effort is half the fun :-)

And that turret... I'd call that insurance. If the balloon doesn't feel like coming down, a couple flak shells will convince it.

Ok, Lew,
you confirmed what I was HOPING to be accurate thought. That yes, at short range most antennas aren't THAT directional, so I point in the general direction and BAM, safely increased range. After all I wouldn't want to do anything imprudent and jepoardize the craft or surrounding properties, people, etc.

Thanks,
Tim

Martin,
I promise, pointing out stuff like the coolness factor is TOTALLY WELCOME in any thread of mine, though it may be shunned by some folks here. I have argued for many years, that if necessity if is the "mother of invention", then laziness is the father, and coolness is the mistress. When Da Vinci invented the elevator to go up and down the cliffs to the beach to do oceanfront work, I don't think necessity was involved. It was one of 2 things. 1- Didn't feel like taking the stair, or 2- frikkin' COOL!! LOL! Rock on my friend, rock on. I might get the big clunky aluminum 15 element beam now! LOL!

Thanks.
Tim

In case anyone's interested, here's a simple to construct, 17dB gain, 2.4GHz quad antenna. Here's the same thing for 1.2GHz. Here's a whole series of antenna designs from the same source (W1HBQ).
