Hi Marcelino
The easiest small good antenna to build is a air cored loop aim for about 1m
diameter or more if you can. In my opinion there will always work better
than ferrites at LF. If you have problems with local inteference then there
are a number of ways of attacking this. Balance is one of the best and
isolation using transformers also can be effective. The cost can initially
be very low, whereas buying a load of ferrote can be quite costly and you
may be disappoined by the results. Remember the success of an antenna
depends much on its surroundings.

As an alternative, the "Miniwhip" does work and works well for many.
Unfortunatley you may just have missed a long thread on that topic and I am
afraid there are no archives on this reflector.

Hello! This is my first post in this group, thanks for letting me join the
group.
I'm doing some test receiving LF, and looking for a good antenna to build.
Searching the web I found this page:
http://www.stormwise.com/page28.htm
It looks they are built with large ferrite rods they advertize in this page:
http://www.stormwise.com/page26.htm
.845" diameter and up to 36 inches long!
