Coca-Loop is a small magnetic loop that uses Coca Cola (Trade Mark) alluminun cans to mount a homebrew trombone variable capacitor for frequency adjustment.
This Magnetic Loop variable capacitor is remotelly controlled by two injection seryngers conected by a long plastic tube filled with water.
One serynger is on the operators hand and the other serynger push and pulls the variable capacitor moving cans according the push and pull hand operator movement..
It covers 17 / 17 / 21 and it is working perfectly.
I have made QSO today a with CX2DK Marcelo in Urguai running a ICOM IC703 (10 Watts) powered by a 12 VDC X 7Amp/H gel cell and the Coca-Loop
There is another video that shows th Coca-Loop on the first indoor mechanic tests http://www.youtube.com/watch?v=gaJlrN3cElo
Thanks for watching
