LP 174-FME
Low-Pass Filter for 0 - 174 MHz
DESCRIPTION
LP 174-FME is an LC low-pass filter.
Allows the whole 0 – 174 MHz to pass.
Can be used, together with HP 380-FME, to prevent possible
interference between VHF and UHF radio systems, e.g. VHF LMR and
TETRA.
Can be used as a preselector to protect a receiver against interferences
from transmitters normally being outside the pass range.
LP 174-FME can be mounted as a preselector directly inside the PRO-
AR4G-N, PRO-AR8G-N and the PRO-AR16G-N receiver multicouplers.
Very small dimensions, mounted in a 45 x 50 mm box.
FME connectors for easy and handy coupling to the surroundings.
LP 174-FME is lacquered with black vinyl enamel to avoid corrosion.
