Do I need a coaxial connector?
A coaxial cable (coax) brings TV and internet signals into homes and other buildings. These cables need connectors on the end to hook up to appliances like TVs and transmit signal. If you have a coax cable without a connector, installing your own is a simple task. Strip the wire and expose its inner conductor.
Is there an alternative to a coaxial cable?
Send Ethernet Signals over Coaxial Cables An alternative solution is Ethernet over Coax (EoC). Also called Multimedia over Coax or MoCA. As the name implies, MoCA technology delivers Ethernet signals over the coaxial cables in the home. If your home has been wired for Cable TV service, then you have coax in the walls.
Are baluns necessary?
Baluns are an essential element in many antenna systems. They enable a balanced antenna or feeder to be transitioned correctly to an unbalanced one like coax that can easily be routed through a building, etc to where it is needed.
How to make a balun with coaxial cable?
These types of baluns built by combining odd quarter-waves of coaxial cable in different configurations is a special case of transmission line calculation that is very simple to calculate compared to other lengths of a transmission line. Zsource*Zload=Zline*Zline.
What does a balun do on an antenna?
My preferred balun for wide and multi-band use is not really a balun as such, it is a choke. Basically, this is a coil in the coax feeding the antenna as close to the feed point as possible. This coil acts as an RF choke and prevents the common mode currents returning back down the feed line.
Is it better to avoid coaxial baluns or to avoid them?
Rather, think about maintaining equal and opposite currents and charges on the shield and center. If you do that, the fields will cancel like this, and the coax won’t radiate. Short answer: No, and in fact you’ll often get more bang for your buck by avoiding coaxial baluns.
What kind of balun should I use for my tuner?
In other installations, both the antenna and antenna feedline are balanced and the tuner has an internal or external balun. Unfortunately, most internal tuner baluns are 4:1 voltage baluns, which we will see is a poor choice. In this case, the baluns should be as close as possible to the tuner.
