 1 Model tower height is defi ned as the distance from

the base of the offset slide to the center of the roll axis.
The height of the model tower assembly will impact
pickup mode in lower positioners containing
an elevation axis. Defi ne elevation measurement
angles and verify lower positioner specifi cations
when confi guring this product.

 2 The lower positioner may require electrical wiring and/

or an RF path to support the model tower. Options are
available for the lower positioner, including EX002, SR,
and RJ. Lower positioner purchased separately.

 3 All accuracy data is based on no-load conditions.

Contact ORBIT/FR for accuracy under load conditions.

 4 Roll axis is equipped with adjustable limit switches

capable of approx 20° up to 900° total travel. When
rotary joint options are specifi ed, limit switches remain
but are electrically disabled. Roll axis is factory-set at
400° (± 200°).

 5 Rotary joint options may alter the original physical

profi le of the roll axis stage. Consult ORBIT/FR.

 6 Verify model tower’s total swing radius (G - clearance

to absorber) when specifying this product for use
inside an anechoic chamber.

 7 Dimensions may vary depending on fi nal confi guration.
 8 Standard offset slide travel is 24 inches. Other lengths

are available in one foot increments.

 9 For special requirements with space limits, the offset

slide can be provided upside-down in order to move
the mast without moving the slide.

 10 An optional alignment fi xture can be installed between

the roll axis positioner and mast, with or without a
base riser.
