Frequently Asked Questions (FAQs)

1. Do coaxial surge protectors work?

Yes, coaxial surge protectors are effective in protecting sensitive electronic equipment from surges and lightning strikes that may enter through the cable line. They provide a reliable means of safeguarding your equipment and ensuring its longevity.

2. Do I need a surge protector for my coaxial cable?

Yes, it is recommended to use a surge protector for your coaxial cable. Surge protectors help divert overvoltage to protect your equipment from potential damage caused by power surges. It is important to install surge protection for all electric current sources, including telephone/fax lines, cable or satellite systems, and local area network coax cables.

3. Can a power surge damage a coaxial cable?

Yes, power surges can cause damage to coaxial cables. Without proper surge protection, surges can travel along these cables and potentially harm your equipment. Installing surge protection for coaxial cables is crucial in preventing damage and ensuring the longevity of your electronic devices.

4. How do you install a coaxial surge protector?

To install a coaxial surge protector, connect a 2-foot cable to the outside antenna. Then, connect one end of the surge protector to the 2-foot cable, ensuring it is properly aligned. Surge protectors are bi-directional, so they can be installed in either direction. Finally, connect the other end of the surge protector to the coaxial cable that connects to the amplifier.

5. What is the downside of using a coaxial connector?

While coaxial connectors have many advantages, there are a few drawbacks to consider. Coaxial cables can be expensive to install for longer distances due to their thickness and stiffness. They also require proper grounding to limit interference. Additionally, there is a safety concern as coaxial cables can be tapped by breaking them and inserting T-joints in between.

6. Can lightning travel through coaxial cable?

Yes, lightning strikes can potentially cause high voltage to travel through coaxial cables, posing a risk of damaging expensive equipment. Using lightning protection, such as surge protectors, is essential to safeguard your coax-connected devices and prevent damage.

7. Does coax shield need to be grounded?

Yes, according to installation guidelines, the outer conductive shield of coaxial cables should be grounded as close as possible to the point of entrance into the building. Grounding the coaxial shield helps ensure proper protection against interference and other electrical issues.
