Amongst some ferrite rods, I have 3 identical, all with LW & MW
windings. I could remove the windings and make a fat bundle of the 3
then wind another coil for an LF preamplifier to improve on my existing
one. Inductors are better not to be long and thin I know but what about
the magnetic cores such as ferrite?
This makes some sense, but I would rather join the rods in line,
retaining a litz wire LW winding which will tune with about 470pF,
ending up with an 18mm PVC tube of about 600mm and a small ABS box in
the centre so the whole looks like a VHF dipole.
Has anyone done this?
Yesterday we were enveloped in a very wet, dripping fog and it seemed to
attenuate my few LF transmissions as nobody received them. UHF TV
disappeared later in the evening too.
The antenna is surrounded by about 100 trees which probably doesn't
help. GW4NOS was on, in S. Wales I think they had a nice, sunny day and
G3XIZ also.
