Final answer:
The frequencies for VHF TV channels can be calculated using the formula f = c/λ. Given the lengths of the wires in the TV-reception antenna, we can determine the frequencies of the channels.
Step-by-step explanation:
To calculate the basic dimensions of VHF (Very High Frequency) airways, there are several factors to consider. Here's an explanation of the steps involved:
1) Frequency band: VHF airways operate within a specific frequency band, typically between 118.000 and 137.000 MHz. This frequency band is designated for aviation communication and navigation purposes.
2) Navigation aid coverage: VHF airways are established based on the coverage provided by ground-based navigation aids, such as VOR (VHF Omnidirectional Range) or DME (Distance Measuring Equipment). These navigation aids transmit signals that aircraft can use to determine their position.
3) Signal strength and interference: The basic dimensions of VHF airways are determined by the signal strength required for reliable communication and navigation. Factors such as terrain, weather conditions, and potential sources of interference, like buildings or other radio transmitters, are taken into account to ensure adequate signal quality.
4) Obstacle clearance: VHF airways are designed with specific dimensions to provide clearance from obstacles such as mountains, buildings, or other airspace restrictions. These dimensions are established to ensure the safety of aircraft flying within the airway.
5) Air traffic volume: The dimensions of VHF airways can also be influenced by the expected air traffic volume in a particular area. High-density airspace may require more airways or wider dimensions to accommodate the increased traffic.
It's important to note that the specific calculations and dimensions for VHF airways are determined by aviation authorities and are subject to regulations and standards. These calculations take into consideration various factors to ensure safe and efficient air navigation.
