I understand that attaching an external antenna will disable the build in
AM ferrite antenna.
My question, is this is a good thing? Will I pick up more with a 100 foot
longware versus a standard ferrite antenna?


The whip is disabled, not the ferrite.


Hello,

From memory I also thought that the external antenna is for short wave
only (so not for the AM broadcast band). The manual, however, says
that is does work on "MW" also (page 35GB). I don't have the receiver
over here so I cannot verify it. The manual also says it outputs DC,
so you need to avoid a short between the ext. antenna input and ground
of the receiver.

Unless you are in a very remote area, 100ft wire at reasonable height
above ground will overload the receiver very likely. You can better
use a shorter wire far from interference sources and use coaxial cable
between the antenna wire and your receiver.

You need to connect your wire to a large metallic structure or ground
away from interference sources, otherwise the cable will guide indoor
interference to your antenna.

Best regards,


Wim
