For many years, several standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz.
However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas were accepted.
Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency.
A.H. Systems' 5 models of biconical Antennas, available from Test & Measurement Australia , operate efficiently over the frequency range of 20 MHz to 330 MHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each biconical antenna will provide reliable, repeatable measurements.
For rapid deployment along with the mobility of a small package, the folding biconical elements can be closed similar to an umbrella allowing the antenna to be contained in an optional transit storage case.
