Physics:Bandstacked
The term bandstacked applies to an antenna or satellite feedhorn (LNBF) that is designed to operate on two or more bands of frequencies. Usually, a portion of the radio frequency spectrum that has been divided into a low band and a high band.
This example is for a C Band LNBF that operates with two different local oscillator frequencies.
Model Number B1SAT STACK I/P Frequency 3.7-4.2 GHz O/P Frequency 950-2050 MHz LO Frequency Lower Band 5.15 GHz, Upper Band 5.75 GHz
One application is to send both H and V signals to the receiver on one cable at the same time. Other LNBF are voltage switched by the receiver for V or H signal.
· Extended Frequency 3.7 GHz ~ 4.2 GHz · Bandstacked LNBF
This also can be applied to the design and construction of VHF antennas, typically base station antennas that can cover the VHF low band and high band. This should not be confused with stacked antenna array configurations.
