Safety Warnings:

The PSC 941 Yagi Antenna has been designed to be inherently safe to use. The design
complies with all current safety, environmental and RF emission regulations. The safe use of

this product is determined primarily by the user. Please read and understand this entire user’s

manual before using your new PSC 941 Yagi Antenna. Proper cabling is a must in, on and
around film and television production sets. Please make sure to route and tape down your RF

must be used when operating this antenna around live power sources.

Overview:

• Frequency Range of 940Mhz to 960Mhz…PSC Exclusive Feature

• Excellent RF Performance

• Approximately 9dBd Gain

• Robust, Skeletal Design

• Switchable Gain via Easy to Use Rotary Knob

• Weather Resistant Design

• Competitively priced, and Made in the U.S.A

Construction:
This new antenna design features a skeletal boom made from CNC machined black Delrin.

This high-performance engineered plastic is rugged enough to provide years of service in the
field. The solid brass elements locked into place using stainless steel cup point set screws to
assure no movement of the tuned elements. A BNC connector rounds out the design.

Connector:

This PSC 941 Yagi antenna uses a standard 50 Ohm BNC connector:

Antenna Placement and Polarization:

Your new PSC 941 Yagi Antenna should be mounted up and away from all of your other sound
equipment. The antenna should be pointed toward the actor worn transmitters. Typically, we
advise that you place the antenna up at least 6 to 10 feet (2-3 meters) above your sound cart for
best performance. The PSC 941 Yagi antenna has mounting provisions for mounting it either
Vertically Polarized or Horizontally Polarized. The Vertical Polarization mounting scheme
generally provides better RF performance. Think of it this way: You want the antenna
elements mounted in the same direction as the transmitter antenna. Most of the time, the body
pack transmitter worn by an actor has its antenna sticking straight upward. This is why we
recommend you mount this 941 Yagi antenna in the Vertical position (with the elements point up
and down)

The antenna can be mounted using an industry standard 3/8”-16TPI threaded base.

This photo shows the 3/8-16 TPI mounting threads.

This Photo shows Vertical Polarization of the antenna.

Use this mounting polarization for most applications.

This photo shows Horizontal Polarization of the antenna.

This mounting position is used when the transmitter’s antenna

is also mounted horizontally.
