Open Wire Feeder Systems (OWFS)

Question 1

What is the purpose of an Open Wire Feeder System?

Answer 1

To provide a means of connecting an aerial to a transmitter or receiver as efficiently as possible.

Question 2

What is the separation distance for Tx OWFS?

Answer 2

Spacing of 260 mm between the wires.

Question 3

What is the separation distance for Rx OWFS?

Answer 3

Spacing of 150mm between the wires

Question 4

What kind of insulators are used in the installation of OWFS?

Answer 4

Type 808 Insulators

Question 5

What are the three different types of networks within an OWFS?

Answer 5

• Routes
• Branches
• Spurs

Question 6

What is the maximum distance an OWFS can span before a mechanical joint is implemented?

Answer 6

Where routes span over 400m they should be divided into sections via a mechanical joint.

Question 7

What tool is used to fix a collet to an OWFS?

Answer 7

Collet is secured to wire at the correct distance using a Collet key

Question 8

At what angle does a Vertical Turn need to be implemented?

Answer 8

To keep the spacing between wires constant when the OWFS changes direction by more than 10 degrees, a vertical turn must be installed

Question 9

What tool is used to apply tension to an Open Wire Feeder System?

Answer 9

• Ratchet Strainer and Tongs

* Draw Vice (Chicago Clamp)
