Preamp for SID VLF antenna

[orfest]

I was looking for a new DIY project for myself and found SID detection. This looks interesting and easy except for the preamp part.

Is it correct that preamps for VLF are not generally available and have to be DIY?

What should be the frequency range of the preamp?

I found some preamp designs for wide range, and some designs for a narrow range of 8-9kHz. Wiki  says that transmitters in Europe use frequency that is at least 11.9kHz.

 

What frequency range should a sid-targeted preamp have? What are people doing with the 8-9kHz frequency range? Which preamp design would you recommend for someone with a very basic electronics knowledge?

 

Thank you!

There are some modules on Amazon, (https://www.amazon.co.uk/d/Semiconductor-Amplifiers/0-01-4GHZ-Wideband-Amplifier-Module-Broadband/B076ZDBGJZ) which are higher frequency than you require, but could probably be modified to get to the range your after...
