What is the ladder?

Linder line is a specific type of transmission wire designed to reduce signal loss. Several defining functions distinguish it from other types of transmission lines, especially in comparison with conventional twins. In many projects do-it-yourself (DIY) could be used another type of ladder line, called an open wire line. There are several applications for this type of line, usually within the tasks of radio transmission. Compared to other transmission wires, it can offer some considerable advantages and some disadvantages.

Twin-Lead, in general, has certain features that are the same as a ladder. This may include parallel wires of copper or copper -coated copper that held each other the same distance with some insulator. Amateur radio stations often rely on Twin-Lead to connect their equipment and help transmission or receiving. In many Cases, plastic straps are used to maintain space. But what makes this wire unique is that the insulator is eliminatedMaterial windows to reduce signal loss and other dielectric effects. This function creates a characteristic appearance of the ladder.

The open line is similar to this wire, except, instead of a consistent cloak separating the wires, evenly distributed insulators usually maintain parallel wires. Like typical twins, plastic insulators may be, but often ceramic, which can offer a significant level of impedance. DIY projects have used an open wire line many times because they can be easily designed and fit into certain transmission requirements.

There are several ladder applications, usually within projects related to radio frequency transmission. Historically, it is used for television antennas, although most of this technology has replaced. FM and HAM radio usually depends on some type of two -color to connect with the receiver antennas.

in general isThe ladder line is considered to be several advantages and some disadvantages over other forms of the transfer cable. During double the ladder line will usually have less signal loss and interference when used. Regardless, as with many types of transmission wire, it is susceptible to interference, especially when the parallel separation of wires is broken. Linker line can also be demanding to configurate, as it must be the right length to not interfere with the radio signals. It must also be protected from direct, permanent contact with metal, which can cause significant signal loss if it remains unchecked.
