Hi Piotr,
compliments..
please can you give us more information about the
dimensions (and material) of the "electrodes" and
how these are routed to the PA ??
What kind of soil do you have? wet? sandy?
thanks in advance

Hi,
I reached OH8HTG WSPR, Â 1414, Â km with my
earth electrode antenna! TX is M1GEO project,
DDS RN3AUS, electrodes are 20 meters apart.
Antenna is directly connected to 50 ohm tx
filter with serial 2,2 nF capacitor. SWR is
about 1,1 to 1.4 according to weather. Direction of the antenna is NE, 50 deg.
So far my WSPR was received in DL, OK, OE corner
by DH5RAE,  DJ0ABR and  DC1RJJ, about 650 km
far. Also closer by SP2OVY and SQ5KLN.
Who can help me estimate EIRP power? I declare now in WSPR beacon 5 mW.
