I'm looking at designs for low cost DIY yagi antennas for a fox hunt, and pondering coat hanger wire and PVC piping. I'd like them to be built by the youth who will be doing the fox hunt, but that requires some safety considerations.
If I plan to bend the tips of the coathanger wire back on themselves to avoid safety issues with the sharp ends, will I cut them to length prior to the bend, or should they be at length after the bend? The bend will be about a plier's width of material, so maybe 5-8 mm, turned back 180 degrees, or nearly so.
I don't have equipment to test for antenna matching, so I can't experiment on this, however these will be used for hunting, not transmitting, so I don't expect it's going to be critical. I'd like to get close, though.
