Hello André,

Thank you for the Antenna and Propagation Manual link.

In our case we chose 300 Hz <<
I assume this should be 300 kHz. Yes, I agree that IMD-measurements can be 
tricky.
For IP2 I often found level differences for the IMD products F1 + F2 and 
F1 - F2.
In this specific case, a different value for the 12 pF capacitor, leads to 
different results. For that reason, I tried the real thing by using BCB 
stations as signal generators. However, there are no nearby very strong BCB 
stations here. I will have to drive 200 km to get close to a Dutch MW 
transmitter site.
Best regards,

Roelof Bakker, pa0rdt
