C. Crane's Twin Ferrite Antenna
I bought this antenna on a 30 day trial, and just got it about 12 hours ago.
So far I'm not at all impressed. I live about 150 miles from an AM station,
at 810, in the SF/SJ Bay Area, which has a marginal signal, but usually
listenable. Putting a new PSU in a PC about a month ago increased the noise
in AM radios 70-100' from the PC to an almost unacceptable level. I had
hoped the antenna would boost the signal enough to knock down the noise.
There are times when I can get a good signal from the station, but certainly
less frequently than before.
The antenna consists of three parts: a 600-1800 KHz control dial, a ferrite
antenna and something called the antenna element. The latter is about 8"
long by 3" by 1.5" (high). The idea is that one puts the ferrite antenna
very near the radio and the antenna element in some other spot, then adjusts
the control dial to the max strength. I detect zero change in any AM
signal from the (C. Crane) radio anywhere on the dial. The antenna element
can be grounded. I modestly did this by hooking a wire (alligator clips)
from the element to the ground socket of an AC outlet (nail in the socket).
No change. BTW, when I was doing the experiment last evening, the signal was
pretty decent during that period. In fact, quite listenable. All this
without the device though.
I'll continue to experiment, but so far not so good. Comments?
