Simon is 100% correct. The dual dipole Radio Jove antenna was designed for receiving Jupiter storm signals on a single frequency. The antennas highest gain (the bright green area) indicates the resonant frequency of the antenna. While not a broadband antenna it is somewhat useful over a larger bandwidth at a reduced gain. Yes the random vertical straight lines are most likely due to lightning either local or distant. The other artifacts do not appear the be Jupiter.

There could be static crashes in there. There could be actual

the diagonal line.)

Question to the radio operators! Have now set up 2 antennas.
So 2x dipole directed on the 15 meter band at a height of 3 m
to receive Jupiter (Radio Jove) at 20.1 Mhz. Receiver sdrduo.
Software sdr console. At 20.1MHz. Bandwidth: 6KHz. 15-24Mhz
bandwidth for Jupiter. What are those many vertical stripes in
the waterfall? Thank you for the answer. Greetings Markus
