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
