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
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the ...
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
In electronics, a local oscillator (LO) is an electronic oscillator used with a mixer to change the frequency of a signal. This frequency conversion process, also called heterodyning, produces the sum and difference frequencies from the frequenc ...
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.{{Citation needed, date=May 2023
