antenna comparison with different setups


Two ferrite rod antennas at 90 degrees, one horizontal Moebius loop with 5 windings and an E-field antenna (start of my recording until Saturday, 2018.02.10 13:30:00)
polar diagram channel 1A, red, H-field, ferrite rod, until 2018.02.10polar diagram channel 1B, green, H-field, ferrite rod, until 2018.02.10polar diagram channel 2C, yellow, H-field, ferrite rod, until 2018.02.10polar diagram channel 2A, pink, H-field, ferrite rod, until 2018.02.10
In the time between 2018.02.10 and 2018.02.25 the antenna setup kept changing. For this resain it is ignored.

Three Moebius loops with one winding at 60 degrees, and an E-field antenna 500 mm (2018.02.25 10:00 - 2018.04.21 17:00).

2018.04.21 17:00 the antenna has been shortened to 130 mm.
In the time from 2018.05.02 until 2018.05.15 08:00 the threshold of channel 2A has been set to 1 mV.
Due to the wrong threshold it has been sent always which looks like a 100% contribution. But this is not correct.
For this reason the time from 2018.04.21 17:00 until 2018.05.15 08:00 is ignored.
