Holland FAM-3HR 3 dB In Line Attenuator with Hi Return Loss
3 dB F type In-line attenuator can be inserted in coaxial cable feeds to reduce signal levels up to 3 GHz. in Frequency with High Return Loss. Reduce UHF/VHF/FM and Digital signal sources such as TV Antennas, Cable TV, Broadband Internet, FM Antenna and Satellite TV (without DC Voltage being present). Combinations of attenuators may be used in conjunction to add up to the exact signal loss needed. High Return Loss means a Higher VSWR, more Accurate Readings and better Impedance Match.
For Power Passing Applications, please use the FAMP-*HR version also listed in this category.
There is such a thing as too much signal sometimes. Receivers of all kinds require signal present within a specific window range for proper operation. Sometimes forcing an Impedance match is the best way to maximize power delivery to Load.
In-Line Attenuators that can Drop Signal Down to Acceptable Levels and Force Impedance match. Some are Power Passing. Most Attenuators Now-a-Days are made of Integrated Circuit Equivalents of Resistors and Capacitors that made up the RC Networks of Yesterdays Pads. Because of this Fact, You will Find that the Actual Loss may vary across the Bandwidth for different reasons and values as compared to Yester-Years Models. I have always found it best to add Attenuation in Increments until reaching the appropriate amount, and then substituting for the Total Value with ONE Pad of equal value. Multiple Attenuators in Series may have Un-predictable and Un-controllable Affects upon each other in Reactance, and are Prone to RF Leakage as Stress upon the Connectors may Compromise the Shield Integrity.
