SAS-542 Biconical Antenna 20 MHz - 330 MHz
The biconical antenna consists of the SAS-542 balun assembly and two
folding biconical elements.
Operation:
Attach the balun assembly to the tripod thru the screw hole in
the balun assembly base. Screw the two biconical elements into the 'tee'
end of the balun assembly. Open the antenna elements completely and
secure in open position by tightening the knurled knobs in the element
caps. Connect a cable between the antenna connector and the receiver.
The biconical beam pattern is similar to a dipole response.
SAS-550-1B Active Monopole Antenna 10kHz - 60 MHz
The active monopole antenna consists of a ground plane upon which are
mounted a preamplifier with internal rechargeable battery pack for battery
operation, and a telescoping rod antenna.
Operation:
Mount the antenna on the tripod. Connect an external ground to
the ground plane if called out in test specification. Attach the telescoping
rod to the connector on the amplifier top and extend fully. Connect the
output on amplifier side to the receiver using a cable. Apply power to
antenna (turn battery power 'on'. The active monopole antenna is omni-
directional.
SAS-571 Double Ridge Guide Horn Antenna 700MHz - 18 GHz
SAS-572 Double Ridge Guide Horn Antennas 18 GHz – 26.5 GHz
The SAS-572 horn antenna comes assembled and ready to use. The
SAS-571 antenna mounting bracket is attached to the antenna backwards
in order to fit in the carrying case. The bracket must be removed from the
antenna, turned over (so that the bracket leg faces away from the antenna),
and re-attached to the antenna. (The bracket is not needed for mounting if
the tripod being used has an Azimuth/Elevation Head.)
Operation:
Attach the antenna to the tripod azimuth and elevation head
through the hole on the antenna bottom or the hole in the mounting bracket.
The ridge guides determine the antenna polarity: for horizontal polarity they
should be parallel to the ground, for vertical polarity they should be
perpendicular to the ground. Connect a cable between the antenna
connector and the receiver. NOTE: BE SURE TO USE A CABLE RATED
FOR HIGH FREQUENCY WHEN OPERATING ABOVE 5 GHz (for
example, the SAC-18G-3 or SAC-26G-3).
MAGNETIC LOOP ANTENNA
SAS-560 Magnetic Loop Antenna 20 Hz - 2 MHz
The loop antenna does not require any assembly.
Operation:
The loop antenna is designed to be held by hand and moved
around each surface if the EUT to measure magnetic radiation. Connect the
antenna via a cable to a receiver with either a 50 ohm input or high
