When the CRX-Relay option is installed the SOLO4 Central Receiver
can be used as a microwave relay.
When used as a microwave relay, the SMA output labelled ‘RF Out’
should be connected directly to an antenna, or to an antenna via a
power amplifier. The following factors should be considered when
connecting the CRX-Relay Option.
•
The use of long cables will reduce the transmitted power level,
therefore Power amplifier devices may be required.
•
The relay antenna should not be placed close to the CRX
receive antennas, to avoid loss of receive sensitivity, filters may
be required to ensure this.
Note: domo can conduct site surveys and frequency planning if required.
4.1 How do I control the CRX-Relay Option
The CRX-Relay option is controlled from the ‘Rebroadcast Tab’ of the
PC Control application. A screen shot of this option is shown below.
