Building a ferrite-rod antenna

[Kellogs]

Dear Friends,

I recently purchased a system mini (received but not yet assembled) and I am looking for information on building an antenna. The most simple seems to be a ferrite-rod antenna. Where can I purchase such an antenna or build my own? I found this website https://www.ferrite-rod-antennas.de/ and contacted the owner.

Kind regards,
Kellogs

I am replying to myself: I purchased two ferrite-rod antennas for 75€ including shipment from https://www.ferrite-rod-antennas.de/.

Kind regards,
