Wouldn't it be better to use a pre-amp at the loop feed? The gain of the pre-amp could make line pickup a negligible effect, and the pre-amp would match the coax very well. -- Ed WB6WSN El Cajon, CA USA It might be. But the extra complication of powering an amplifier would bring another load of things to worry about. Simplicity is a wonderful thing. By far the best way of improving performanc and reducing possible measuring errors, is to increase size of loop relative to length of feedline. Doubling dimensions would make a world of difference. I suppose he had a good reason for choosing a 1/2-metre square loop. ---- Reg, G4FGQ |
