7.4. Circular LNB Options
The Coastal Series antennas can be easily fitted with a variety of
circular
LNB assemblies. A
circular
feed
tube must also be installed. Together they (the feed tube and the LNB) are capable of receiving
circular
polarization, however, the LNB must match the frequency band of the desired
circular
polarized satellite.
Below are the
circular
LNBs which may be used with this system when the
circular
feed tube is installed.
