Overall View of completed Receive Loop antenna

Optional Pre-Amplifier and Attenuator

A perfect companion to the DXE-NOISELOOP is the optional
Pre-Amplifier/Attenuator

DXE-NL-PRE-ATT-1.

It uses an

internal 9 volt battery, has BNC connectors for Input and
Output, Easy to use slide switches and a power on LED when
the Pre-Amp is turned on. Selectable attenuations levels of -10
db, -20 db (and -30 db when both are on), plus an additional
AM filter can be switched in when needed. Note that this is a
Receive Only system. Transmitting RF will damage the unit
and it is not covered by warranty.
