Coax Cable Distance Calculator

Formula

To calculate the maximum distance (\(D\)):

\[ D = \frac{Vf \times C}{f} \]

Where:

\(D\) is the maximum distance (meters)
\(Vf\) is the velocity factor
\(C\) is the speed of light (approximately 299,792,458 meters per second)
\(f\) is the frequency (hertz)

What is Coax Cable Distance?

Coax cable distance refers to the maximum length over which a coaxial cable can effectively transmit a signal without significant loss or degradation. This distance is influenced by factors such as the cable's velocity factor, the frequency of the signal, and the inherent properties of the cable material. Understanding the coax cable distance is crucial for ensuring optimal performance in applications like television broadcasting, internet connectivity, and radio communications.

Example Calculation 1

Let's assume the following values:

Velocity Factor (\(Vf\)) = 0.66
Frequency (\(f\)) = 100,000,000 Hz (100 MHz)

Using the formula:

\[ D = \frac{0.66 \times 299,792,458}{100,000,000} \approx 1.98 \text{ meters} \]

The maximum distance is approximately 1.98 meters.

Example Calculation 2

Let's assume the following values:

Velocity Factor (\(Vf\)) = 0.85
Frequency (\(f\)) = 500,000,000 Hz (500 MHz)

Using the formula:

\[ D = \frac{0.85 \times 299,792,458}{500,000,000} \approx 0.51 \text{ meters} \]

The maximum distance is approximately 0.51 meters.
