Applications

VRD-1FF

VRD-1FF CATV isolator

• Improves audio/video quality by reducing 60 Hz ground currents

• 2 MHz to 1300 MHz bandwidth spans VHF/FM/UHF/CATV spectrum

• Capacitive based design minimizes broadcast channel interference

• Meets FCC Part 76 Regulations for CATV systems

The Iso•Max VRD-1FF is a high performance capacitive isolator that has

been meticulously designed to break the ground loop that causes hum and

buzz in audio, 60 cycle hum bars in video or introduces frequency dips that

cause channels to drop in digital cable.

Housed in a compact cylinder, this second generation VRD-1FF employs

a unique RF engineered solution that delivers a ruler-flat response from

2 Mhz to over 1300 MHz spanning the VHF/FM/UHF and CATV spectrum.

Gold plated F connectors are carefully machined to ensure true 75 Ω com-

patibility for optimal signal integrity and minimize reflections or ghosting.

Plug and play easy to use, this passive solution doesn’t require any power.

One simply inserts the VRD-1FF in series with the incoming signal and it qui-

etly goes to work without degrading the signal. This makes the VRD-1FF a

‘must have’ for the AV technician that is servicing and installing digital cable

as well as conventional CATV or VHF/UHF antenna or MATV systems.

Connectors are nickel plated brass

“F” type with gold plated contacts.

Either connector may be used for input or output.

VRD-1FF with digital cable tv

The Iso•Max VRD-1FF is the perfect

‘trouble-solving partner for digital video

transmission problems. It isolates the

source and destination without introduc-

ing frequency dips that cause channels to

drop. It works equally well to get rid of au-

dio hum and buzz with standard cable TV.

Distributing video in large facilities

Distributing video around a large facility

such as an airport, arena, or convention

hall can often lead to quality picture prob-

lems caused by uctuating voltage refer-

ences at various power drops. The VRD-1FF

isolates the local monitor from disruptive

DC currents.

Solving CATV hum bars

When interfacing a distant camera to a

video system, hum in the form of 60 cycle

hum bars will often nd their way into the

picture. The Iso•Max VRD-1FF provides a

plug & play solution that eliminates the

problem-causing stray DC currents without

aecting the video quality.
