A.2 LNA 10 Low Noise Receive Amplifier
The LNA 10 is a high-performance, low-noise preamplifier designed to enhance
fringe area reception and provide additional gain on the receive antenna. Its
exceptionally small size and light weight enables it to be directly mounted on the
antenna by means of the female RF IN connector. Power is obtained through an
RG-59 coaxial cable connected to the power supply. The LNA 10 is internally
protected against lightning and voltage surge protection.
The Power Supply (PS) and Power Inserter are supplied with the LNA 10.
The RG-59 coaxial cable with F-type connector is not supplied and must be
purchased separately.
A.2.1 Installing the LNA 10
Before installing the LNA 10, the following steps must be taken:
1. Choose one of the antenna connectors to be used for reception. This
connector is called the receive antenna of the unit. The other connector is
called the transmit antenna of the unit.
2. Use the terminal to set the unit’s transmit diversity option to the selected
antenna (see Section). This prevents transmission from going through the
LNA 10.
3. Connect the LNA 10 RF input directly and as close as possible to the receive
antenna.
4. Attach the LNA 10 RF output directly to the RF cable going down to the
receive antenna connector on the BreezeACCESS unit.
5. Connect the RG-59 coaxial cable which leads down to the Power Inserter to
the Signal and Power out connector on the LNA 10.
6. Connect the Power Inserter to the power supply (both are indoor units).
7. For transmission, use a separate antenna connected to the other antenna
connector (transmit antenna) of the BreezeACCESS unit.
