AOR ABF-128-SMA airband filter is designed for frequencies between 108 and 136MHz.

AOR ABF-128-SMA airband filter is designed for frequencies between 108 and 136MHz.


The AOR ABF128-SMA is a receive bandpass filter specially designed for severe VHV.H.F.irband listeners. This filter improves the strong signal handling characteristics of scanners and wideband receivers utilising SMA-type antenna connectors for VHV.H.F.ommercial Airband listening. The ABF128-SMA is suitable for connection to most scanners and wideband receivers on the market, regardless of brand. Adding this filter to the antenna's signal path provides additional selectivity, enabling the receiver's circuitry to better cope with strong interfering signals that can leak into the 108-136 MHz VHV.H.F.ir band. The ABF128-SMA provides additional selectivity to any receiver's front end by reducing many unwanted strong signals from reaching and saturating the receiver's first mixer stage. This results in less interference and improved reception.

The ABF128-SMA offers excellent out-of-band attenuation, typically 40 dB below 87MHz and 40 dB above 170MHz. This makes the ABF128 suitable for connection to both external antennas and for connection directly under the whip antenna of a hand-held receiver. A SMA jack (female) is mounted to the top of the ABF128- SMS.M.A.nd a SMS.M.A.lug (male) to the other making connection to an antenna easy and straight forward. The ABF128-SMA is not an amplifier so will not boost signals, however the additional selectivity offered can significantly improve reception in many situations by removing unwanted strong signals which may overload the receiver and reduce it's effectiveness. When any connection is fitted to the antenna signal path, some reduction of the signal results (attenuation); however, the ABF128-SMA in-band attenuation level is minimal due to the excellent in-band V.V.S.W.R.f 2:1, resulting in a loss of only about 4 dB.
