Features
Frequency range: 30 MHz to 300 MHz
Collapsible antenna elements
Part of ANK series antenna kits
Individual Calibration
Three year warranty
Application
The ABF-900 Biconical antenna has collapsible an-
tenna elements for easy storage and transport. It
is good choice for off site EMC measurements. The
broadband characteristics of the ABF-900 antenna
make it ideal for making sweep measurements. It
can be purchased separately or as part of the ANK-
310, ANK-910L and ANK-910M antenna kits.
In addition to emc emission or immunity measure-
ment, the biconical antenna can be used for site EMC
site calibrations. The ABF-900 Biconical antenna
has smaller elements and is easier to use. Especially
for vertical site attenuation measurements at low
frequencies. Dipole antennas which are typically
recommended for site calibration have long element
lengths at lower frequencies (5 meters at 30 MHz)
According to ANSI 63.4 specification, a calibrated
biconical antennas can be used for site attenuation
measurements.
The calibration data provided with each antenna is
used to calculate field strength measured for the
selected frequency. The antenna factor (dB/m) for
the selected frequency is added to the measured
output (dBV) displayed by the EMI receiver to obtain
field strength (dBV/m)
Description
The ABF-900 is a linearly polarized broadband Biconi-
cal antenna. It has a frequency range of 30- 300 MHz.
It has the same performance as the AB-900, but it is
shipped with a set of collapsible conical elements.
This antenna is part of the ANK series antenna kits.
The ABF-900 antenna has a N type connector. The
antenna is capable of handling up to 50 Watts of
input to generate electromagnetic fields during
EMC immunity testing.
These antennas are individually calibrated at 10 me-
ter distance using procedures described in ANSI 63.4.
This data is shipped with each antenna. Optional
calibration at 1 meter or any user specified distance
is available upon request. Accredited calibration
services are also available.
The ABF-900 balun has a 1/4 inch x 20 threaded hole
on the back. It can be mounted on Com-Power AT-120
tripod or any other antenna tripod with matching
threads. It can be also mounted on a antenna mast
with a similar mounting arrangement. As an alter-
nate mounting method, ATC-001 clamp can be used.
This clamps fits around the PVC tube on the balun
to securely attach the antenna to a tripod or the
antenna mast without the threaded mounting bolt.
