Out
of curiosity, are most stations in Europe using directional RX
antennas or only omnidirectional/TX antenna? Most of us here state
side that have made it across at one time or another using WSPR or
other modes are using directional antennas. Just a matter of curiosity
on my part.
As far as i know, most stations arround EU are using omnidirectional
antennas. Maybe 10% are using loops or cardioid antennas? I know F6CNI
and F1AFJ are using cardioid antennas.
On my RX location in the city i'm using a small active omnidirectional
E field antenna. On my remote RX site i'm preferring a loop beaming
NW/SE. In some time i will have finished my stereo receiver for MF. The
i can decide to use a T-antenna or a loop or a combination out of these
two antennas resulting in a cardioid system. The advantage over e.g. a
K9AY design is that i can use the configurations simultaneously,
i.e. i can build (in SpecLab) a cardioid antenna beaming to NW AND a
cardioid antenna beaming to SW AND an omnidirectional antenna,
receiving to the same time :-)
