Most antennas and radios are designed to operate at 50 ohms, so using a 50-ohm cable like the MB8L is usually the best choice.
Signal Loss (Attenuation)
Signal loss, also known as attenuation, refers to the reduction in signal strength as it travels through the cable. Signal loss is typically measured in decibels (dB) per unit length, such as dB per foot or dB per 100 feet. The MB8L cable is designed to minimize signal loss, but all cables will experience some degree of attenuation. The amount of signal loss will depend on the cable length, the frequency of the signal, and the quality of the cable. Higher-quality cables, like the MB8L, typically have lower signal loss characteristics. When selecting an antenna cable, it's important to consider the signal loss specifications and choose a cable that will provide adequate signal strength for your application. You can use online calculators or consult with a radio expert to estimate the signal loss for a given cable length and frequency.
Shielding
Shielding is the process of protecting the cable from external interference. The MB8L cable typically features a shielded design, which helps to block unwanted RF signals from entering the cable and interfering with the desired signal. Shielding is particularly important in environments where there are high levels of electromagnetic interference (EMI), such as near radio transmitters, electrical equipment, or industrial machinery. The shielding is typically achieved by wrapping the inner conductor with a conductive layer, such as braided copper or aluminum foil. The effectiveness of the shielding is measured in decibels (dB), with higher numbers indicating better shielding performance. A well-shielded cable can significantly improve the signal quality and reduce the risk of interference.
Weather Resistance
Weather resistance is an important consideration for antenna cables that will be used outdoors. The MB8L cable is typically constructed with a rugged outer jacket that protects the inner conductors from the elements. This outer jacket is often made of materials like polyethylene (PE) or polyvinyl chloride (PVC), which are known for their excellent weather resistance and durability.
