40dB Crossband Couplers 25-175MHz/400-960MHz Weather Proof Tower Mount - Rx Only (Watts)

SP0000-1110-85

Crossband couplers allow the combining of multiple frequency bands onto shared coaxial and radiating cables and multi-band antennas. Models are available for specialised transmit and receive applications across the frequency range 0.5 - 2500MHz and beyond. Cascading units can allow any number of different frequency bands to be combined together.

SP0000-1110-85 Features:

In addition, units are available for indoor, outdoor and tower mounting requirements thereby providing for the rationalisation of feeder cable usage - reducing cabling costs and tower loadings.

• Suits analogue and digital technologies
• Combine multiple frequency bands for Distributed Antenna and Radiating Cable systems
• Reduce cabling and tower loading
• Add new frequency bands to existing installations
• Indoor, outdoor and tower-mount versions available

A crossband coupler is typically a three port device - usually known as low-pass, high-pass and combined respectively. Models are available in a variety of mounting styles and DC-Pass or DC-Blocking configurations for use with bi-directional amplifiers and tower mount preamplifiers. Tower mount (outdoor) models shown consist of the indoor unit less rack mount bracket, in a weatherproof fibreglass housing that is sealed with silicon adhesive. Indoor units may also be packaged in suitable custom weatherproof housings to create alternate tower mount versions.

Notes:
1. Passes DC power between all three terminals for operating separate tower mount receive systems. Warning: Do not connect a DC grounded antenna directly to this model if DC power is being passed.
2. DC power will only pass between the combined port and the 800-960MHz port for operating a 800MHz tower mount receive system.
3. DC power passes between the combined port and the 400-540MHz port, but is blocked from the 25-175MHz port to the combined port.
4. DC power passes between the combined port and the 400-540MHz port, but is blocked from the 800-960MHz port to the combined port.
5. The 0.5-1.6MHz port is coupled onto outside conductor of combined port and 60-1000MHz port is coupled onto centre conductor of combined port. This model is used for combining AM radio rebroadcast with FM/VHF/UHF/etc onto a single cable.
