Hm yes, maybe. But if you are outside in the nature (thinking about a total /p station consisting out of that antenna and a sensitive RX, a netbook running SL and a 70cm handheld TRX, and sitting on a bank watching the sky!) where no man made QRM is and point the antenna to the wanted signal... The DCF77 clock antennas at home are probably often pointing somewhere, rather to the neighbours PC instead to Mainflingen.
And it must be a large rod or probably many of them in parallel and seriell using a LNA as well. Must be separated from the SL running PC.
I assume many have tried this before, most probably some of the reflector members too.

Further comments?

I haven’t thought about ferrite RX antenna for LF….My guess is that it is not going to work – not without an external antenna coupled to the ferrite, and then what’s the point?
DCF77 clocks often have trouble locking indoors or in the neighborhood of ‘QRM’ generators like PC’s, and look what power DCF77 is using…
I could be entirely wrong of course…

BTW what do you think about a ferrite RX antenna for LF? Now i'm opening an older discussion i expect ;-)
