The tilt in the base station antenna can be adjusted by physically changing the angle of the antenna.

• Tilt can be adjusted by loosening the bolts on the antenna mount and manually changing the angle of the antenna

• Specialized tools like tilt meters can be used to ensure the correct angle is achieved

• Remote electrical tilt (RET) systems can also be used to adjust the tilt of the antenna electronically

Array antennas are designed by arranging multiple antenna elements in a specific configuration to achieve desired radiation pattern and performance.

• Determine the desired radiation pattern and performance requirements

• Select the type of array configuration (linear, planar, conformal, etc.)

List and tuple are data structures in Python used to store multiple items. Lists are mutable, while tuples are immutable.

• List is denoted by square brackets [] and can be modified after creation

• Tuple is denoted by parentheses () and cannot be modified after creation

• Lists are used when the order of elements needs to be preserved and elements can be changed

• Tuples are used when the order of elements needs to be preserved but elements should not be changed

• Example of list: my_list ...read more

Reading CSV without pandas involves using built-in Python modules like csv.

• Use the csv module to open and read the CSV file

• Iterate through the rows and process the data accordingly

• Handle any necessary data conversions or manipulations manually
