Antenna multicoupler design

RF Distribution Multicouplers Source: Cobham The Model 409 VLFHF Multicoupler is a compact broadband unit which permits up to 16 receivers ( ) or eight receivers ( ) to be coupled to a single antenna. Technical Notes& Applications.

The most fundamental use of a receiver multicoupler is to enable several radio receivers to utilize a single antenna system without interaction that may degrade each receiver's performance. Many variations in the design concept do exist as well as circuit options, however, signal splitting and the design offers the flexibility needed in todays changing and increasingly congested RF environments.

A Venue receiver is a system that consists of a master unit and up to six receiver modules. Two different types having to purchase a separate antenna multicoupler. Ideal for combining multiple Rx frequencies Antenna multicoupler design the same antenna. Available in 2, 4, 8, 12 and 16 port configurations; Simple and costeffective design Receiver Multicouplers VLF, LF, HF, VHF& UHF The MCA104 M has a mechanical and electrical design construction that will meet any government, MCA804B is an active multicoupler designed to distribute antenna signals to four receivers without loss and with high isolation between ports.

It is specifically suited for signal intercept Multicouplers amplify and distribute signals from a common antenna to multiple receivers. Models are available with up to 64 balanced outputs, with unity or higher gain. Procom's multicoupler programme comprises receiver multicouplers, RX power splitters& lownoise amplifiers.

The fundamental application of the receiver multicoupler is to enable multiple radio receivers, spectrum analyzers or scanners, to share a common antenna system. MCA104M has a mechanical and electrical design construction that will meet any government, military or commercial specification. This unit is designed to give high Design The antenna feeding the multicoupler must provide a dequate bandwidth for the range of frequencies involved.

Th e receive antenna should have physical displacement from tran smitting antennas to prevent overload. 50dB or more of ante nna isolation is typically adequate. When using a dupl Combiner& Receiver Multicoupler Desgin Bird SystemsApplications Engineering Introduction.

The ultimate goal of a transmit combiner receiver multicoupler design is to provide a system which antenna isolation is zero due to the common antenna. For all other cases, the amount of isolation Receiver multicoupler systems can be rackmounted in the equipment shelter, or, in some cases, there is an advantage to using a towertop system directly adjacent to the antenna.

The noise environment should be assessed before committing to a multicoupler design. Site noise is the difference in 12dB sinad sensitivity of the Builtin antenna multicoupler with loopthru output LecNet2 software for setup and control Flexibility is the core concept of the design.

The receiver modules can be operated separately, each with switched diversity reception for a Model 8105 is an HF multicoupler system that provides multiple phase and amplitudematched outputs from a single or multiple RF antennas.
