i have not tested this, however, i would like to experiment a little more. i have just been told it works great.
The modern radar reflector uses exact 90 degree angles to create a large echo. (Think about the game Pong where you aim the ball into a corner and it comes right back at you.) It's worth the $50 to get one, rather than experimenting with somehting that will not work very well versus the space it takes-up aloft. In other words, if you took $50 of aluminum foil crunched it a bit and wrapped it around 5 huge cardboard boxes that were used to ship refrigerators, and then hoisted that aloft, it would probably relfect about as well as the modern $50 reflector - and maybe not.

It's $50 well spent and you may even be able to pick one up on eBay or Craigslist for cheaper than $50.

Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing. I don't know why. It's a mystery!
