Active antenna

[truffaldino]

Hello,

I am wandering if anybody has a circuit diagram for a simple antenna preamplifier that can be attached to a micro 40 mhz fm receiver to extend the range?

Will be grateful for info

Thanks Tito,

This is a good solution, but this ic is unavailable here in Italy.

I am wandering if it is possible to use a simple circuit with a high speed (readily available) opamp for the preamplification.

I have also tried single JFET circuits widely posted on the internet, but they do not work.

Best Regards
