Dressler NIB (still sealed in shipping box) $450 shipped ARA100HDX

covers 40 kHz to 100 MHz and is designed for the interception of weak
signals even in the presence of strong broadcast station signals. The
ARA 100HDX is a alternative for those who do not have the space for a
traditional outside wire antenna. It is compact and unobtrusive. The
output impedance of the antenna is always 50-75 ohms, independent of
frequency. This allows efficient connection directly to the receiver
without an additional antenna tuner. The ARA100HDX will not overdrive
most portables.
