The RF distribution product range can be broken down into the following categories:
Multicouplers are designed to allow a set of radio receivers to simultaneously connect to a single antenna (single input, multiple output). As well as providing improved radio system performance, the range of multicouplers also provide the system with comprehensive protection from high-level signals and electrostatic discharge.
When multiple antennas are required to be connected to multiple receivers a switching matrix is needed. When the system also requires any number of receivers to be connected to any antenna simultaneously, the matrix is termed non-blocking. Drumgrange make a range of non-blocking matrix switch units for switching/routing off-air signals to receivers.
Non Blocking Matrices & Switches
The non blocking matrices are housed within a single 19" rack mounting enclosure, complete with control module and mains power supply.
Key features are:
Signal exchange units can be configured to provide independent matrix switching of inputs to outputs. By combining the two units with a series of single pole double throw RF switches on the output, the system becomes a non-blocking multi input x multi output matrix system. Switch sizing is solely dependent on the selection of matrices hence a variety of systems can be configured in this way.
A range of wideband masthead pre-amplifiers to cover the VHF/UHF bands are available. These pre-amplifiers greatly improve the RF sensitivity of fixed-site and transportable systems, whilst preserving maximum dynamic range.
Key features of the wideband masthead pre-amplifiers used for monitoring and communication systems are:
In addition to the specific products identified above, Drumgrange supply a range of general RF products. The products listed below cover a wide range of frequency bands and have different types of connector configurations. These components can be re-configured to address any customer requirements. If you have a specific requirement for any of these types of products please contact Drumgrange.
Radio Direction Finding
Drumgrange has a wide range of radio direction finding (establishment of the direction from which a received radio signal was transmitted) products.
Some of these products are highlighted below:
