Interesting the results people mention . . .
The net noise reduction on my homebrew 6ft multi-turn resonant loop up in the loft (after adding a preamp to bring signals up to the same level as my Tx antenna) is also about 6dB. Although that doesn't sound a lot, of course it is HALFING the background noise . . . and makes all the difference between copying a weak station and not. It's also interesting having a vertically-polarised Rx antenna, and noting any change in signals when switching between that and my Tx antenna, which is a horizontal dipole. There's no way I could put up a K9AY, let alone a Beverage . . . so I'm pleased my Loop up in the loft seems pretty good. It's very cheap to make, so if anyone wants to build one - the details are here: http://rogerkennedy.co.uk/g3yro/160mrxloop.htm 73 Roger G3YRO _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
