Operating instructions

Suppress TV interference at the source with the LP-2500
Low Pass Filter
Use between Transmitter and
Antenna or Tuner. Reduces TV
interference (TVI) radiated by
transmitters operating below 30
MHz. Suppresses harmonics
appearing in the TV bands. Add-
itional attenuation to TV IF fre-
quencies above 40 MHz. Low loss
to 30 MHz. 9-pole inverse Chebyshev.

Suppress TV interference
with the HPF1 High Pass Filter
Use between Cable and VCR or TV set.
Reduces signals received from transmit-
ters operating below 30 MHz. Low loss
in the TV passband 52 to 550 MHz.
Unique shield breaking circuit prevents
cable from acting like an HF antenna.

More than -55 dB at 20 MHz;
More than -40 dB at 30 MHz
Impedance: 75 Ohms
Insertion Loss: Less than 0.5 dB @ 52-550 MHz
Connectors: CATV (Type F) 75
Dimensions: 3.25Wx1.5Dx2H inches.
Suppress the more severe TV interference with the HPF2
Deluxe High Pass Filter
Use between Cable and VCR/TV set. Reduces TV interference (TVI)
from nearby radio transmitters (like broadcast, commercial, two-way,
amateur, and CB below 30 MHz. Unique common-mode rejection
(RF current on the shield of coax cable) using a toroid ferrite core.
SPECIFICATIONS:
Passband: 52-550 MHz
Cutoff Freq: 50 MHz
Attenuation: More than 80dB: 1-14 MHz;
More than 70 dB: 14-25 MHz;
More than 50 dB: 25-30 MHz
Impedance: 75 Ohms
Insertion Loss: Less than 0.25 dB @ 52-550 MHz
