Com-Power AB-900A – Biconical Antenna, 25 MHz to 300 MHz

• 25 MHz to 300 MHz
• Emissions/immunity applications
• ANSI C63.5 or SAE ARP958 with NIST traceability
• Three-Year Warranty

The AB-900A is a broadband, linearly polarized Biconical Dipole Antenna, operating over the frequency range of 25 MHz to 300 MHz. It can be used as either a receiving antenna (for EMI measurements) or as a transmitting antenna (for immunity tests) for power levels up to 50 watts.

Construction

The antenna elements are constructed using a corrosion resistant aluminum, which is powder coated for additional durability. Implemented in the element design is a “gamma match” rod, which connects the element’s center rod to one of the outer elements at the inside edge of the 90 degree bend. The gamma match is necessary in order to avoid a significant “dip” in the antenna’s performance which would otherwise be present between approximately 275 and 290 MHz.
