DCF77-SHO Active Antenna Kit V2
The kit includes all active and passive components, including an unpopulated circuit board (74mm x 60mm x 1.6mm).
The kit also includes the ferrite antenna (shotech 001676) and the enclosure (strapubox 516 shotech 001700).
Components C2 and C3 are not included, as they are not required for the construction of the active antenna with the tuned ferrite antenna.
It is recommended to use a 50-ohm coaxial cable (RG316, RG178, RG174, etc.) for connecting to the DCF receiver.
The V2 version of the kit allows this active antenna to be operated with a voltage of +12V. The additional electronics have now been integrated onto the circuit board. (R6, R7, C6, C7, D1)
Another external voltage, such as +12V, is also possible; for this, resistor R7 must be recalculated. The external voltage with
the new optional module should not be less than +11V.
