For the discriminating scanner user who needs the best possible weak-signal amplification without amplify-
ing the noise as well, this tiny (1” square) preamp is the answer!
The LN4000 offers 20 dB (typical) signal amplification from 100-4000 MHz (-3 dB), at
a low noise figure of only 4.5 dB. It is powered by any convenient 5 to 12 VDC, 30 mA
(typical), center pin positive, power supply (available as an accessory).
Includes 10” coaxial receiver/scanner interconnect cable with SMA connectors and
BNC adaptors. A 10’ power supply cable with DC connector is also provided for remote
mounting.
NOTE: Antenna preamplifiers increase the strength of strong signals as well as weak. If you
experience strong-signal overload, a filter for the offending frequencies is recommended.

The ABF128 is a receive (only) bandpass filter especially designed to improve strong signal handling characteristics
of receivers for VHF commercial Airband listening. The AFB128 is suitable not only for AOR receivers, but also for
most airband and wideband receivers on the market. The addition of ABF128 will provide additional selectivity,
and allow the receiver’s circuitry to cope much more easily with strong interfering signals such
as Band-2 Stereo or Shortwave broadcast transmissions.

Now you can restore quiet monitoring on your scanner or VHF/UHF transceiver,
drastically reducing that incessant “bleep bleep” interference from local paging
transmitters! Simply specify whether the interference is from a 152, 158, or 462
MHz pager, and we’ll send you a unit that knocks down that interference by 35 dB! Units
may be cascaded for additional interference reduction. Equipped with BNC connectors.
Filters are drop-shipped from manufacturer.
