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 u ...
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, the term local oscillator (LO) refers to an electronic oscillator when used in conjunction with a Frequency mixer, mixer to change the frequency of a signal. This frequency conversion process, also called Heterodyne, heterodyning ...
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
Base station (or base radio station, BS) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a " land station in the land mobile service."
A base station is called '' node B'' in 3G, '' eNB'' in L ...
antennas that can cover the VHF low band and high band.
This should not be confused with stacked
antenna array
An antenna array (or array antenna) is a set of multiple connected antenna (radio), antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called ''elements'') are usually connected to a s ...
