The first part is real, the second is full of intermodulation products.

Hello Apex friends!

We have severe problems with the Apex-30 here in Germany due to intermodulation interference.

We don't have these problems when using an Apex-12.

Can it make sense to reduce the ferrites of the couplers on the Apex-30?

How does that work?

The opposite can be seen with the Apex-12, which brings relatively little signal strength.

Does it make sense here to increase the number of ferrites in the couplers?

Here is a comparison of Apex-12 and Apex-30: https://nextcloud.csww.de/s/DiBZ2J6tLLcDj45

Best regards
