DESCRIPTION
The model AHA-118 Active Horn Antenna is basically the AH-118 Horn Antenna with an integrated preamplifier. The preamplifier has a nominal gain of 20 dB for the entire frequency range. The preamplifier improves the effective system noise performance for emissions testing as explained below.

Features:

• Frequency Range: 1 GHz to 18 GHz
• VSWR: 2.0 :1
• Polarization: Linear
• Output Impedance: 50 Ω
• Connector types: Antenna output: N (f); Preamplifier input: N (f); Preamplifier output: N (f)
• Power input: 18 VDC, 500 mA
• Weight: 7 lbs. (3.1 kg)
• Size: 10.2" X 9.5" X 5.6" (25.9 cm x 24.1 cm x 14.2 cm)
• AH-118 is linearly polarized and has a frequency range of 1 to 18 GHz.
• Constructed using lightweight aluminum with a corrosion resistant conductive coating
• Rear mounting plate of the AHA-118 has 1/4 inch x 20 threads; allowing the antenna to be mounted on a model AT-100 antenna tripod or any tripod with similar mounting arrangement
• Powered by an external DC supply, which is shipped with it
• Output of the antenna is connected to the preamplifier by a short low loss cable, which can be removed
• Arrangement makes it possible to (1) insert a filter before the amplifier and (2) use the antenna alone for transmission
• Filter insertion capability is important and is required in presence of a high-level signal (such as fundamental frequency), which possibly could saturate the amplifier if the filter is not used
