Today I have been refurbishing my magnetic-loop (magloop) radio aerial. This type of aerial has become very popular for listening to distant radio stations on MW & SW. They really came to the fore a few years ago when a company called Wellbrook were selling them at £350. Mine is something I built (threw together) myself. The loop is a length of insulated wire fed down the bore of some copper brake-pipe tubing (which has a gap in the middle) and that is supported on some old plastic water pipe (the loop is 1m in diameter). The ends of the insulated loop connect to a coax feeder and then to a small 2-transistor amp and that feeds the receiver. The loop is largely "immune" electronic noise from many domestic electronics these days which badly effects conventional long-wire radio aerials. I think the total cost of mine was ~£15? Sadly, I managed to cut through the coax line with my hedge trimmer in the summer, so repairs were needed before the weather turns.
