In heavy submarine cables, loading coils were difficult to lay.
Rather, the purpose is to cancel or greatly reduce the effect of the loading coils fitted to a line.
Loading coils are still used in long cables.
It is necessary to remove or cancel any loading coils in the line before equalization can be successful.
The invention of loading coils extended the range to Denver in 1911, again reaching a technological limit.
Loading coils can still be found in some telephone landlines today but new installations would use more modern technology.
In 1887, Heaviside introduced the concept of loading coils.
Add loading coils to reduce the attenuation of voice signals over long loops.
It works because the loading coils used on balanced lines have two windings, one for each leg of the circuit.
Loading coils were not without their problems.
Answer: because electromagnetic radiation fries line loading coils, amplifiers, and repeaters.
It is also possible to load a cable of conventional construction by adding discrete loading coils at regular intervals.
The weight of early submarine cables using loading coils could cause excessive stress in the cable if not handled carefully.
The capacitance can be compensated by adding an equal value inductance, a loading coil in series.
These electrically short antennas need loading coils of high inductance to bring them into resonance.
Several vertical radiator wires hang down from the top-load, each attached to its own ground through a loading coil.
When this is not possible, masts with a loading coil, 'capacity hat' or similar loading arrangement are used.
Its construction also makes it expensive compared to the previously existing method of adding discrete loading coils at intervals along the cable.
The loading coil may be on the bottom, middle, or top of the antenna, while some antennas are wound in a continuously-loaded helix.
Campbell's filter was a lumped-element design of capacitors and inductors suggested by his work with loading coils.
Campbell was tasked with continuing the investigation into Stone's bimetallic cable, but soon abandoned this in favour of the loading coils idea.
In fact, neither man was the first to suggest the idea of loading coils, that credit goes to Oliver Heaviside in a 1887 article.
The masts are inductively lengthened and fed by a loading coil (see: electrical lengthening).
Additionally, the large inductance of the loading coil creates a very high Q antenna system, with an extremely narrow bandwidth.
Because twisted pair is a balanced format, half the loading coil must be inserted in each leg of the pair to maintain the balance.
In heavy submarine cables, loading coils were difficult to lay.
Load coils cause distortion in voiceband on very long lines.
Rather, the purpose is to cancel or greatly reduce the effect of the loading coils fitted to a line.

But one crucial one involved the placement of devices known as load coils along its length.
Load coils are commonly used in cellphone antennas to alter their current patterns.
It works because the loading coils used on balanced lines have two windings, one for each leg of the circuit.
Load coils are, in essence, filters that block out any non-voice frequency.
In this context a line without load coils is referred to as an unloaded line.

American early and middle 20th century telephone cables had load coils at intervals of a mile (1.61 km), usually in coil cases holding many.
Its construction also makes it expensive compared to the previously existing method of adding discrete loading coils at intervals along the cable.
