With loading coils, signal attenuation of a circuit remains low for signals within the passband of the transmission line but increases rapidly for frequencies above the audio cutoff frequency. The phenomenon of cutoff whereby frequencies above the cutoff frequency are not transmitted is an undesirable side effect of loading coils (although it proved highly useful in the development of filters). The cutoff effect is an artifact of using lumped inductors. Loaded cable is no longer a useful technology for submarine communication cables, having first been superseded by co-axial cable using electrically powered in-line repeaters and then by fibre-optic cable. The communication system offers a reduced instruction set to read and write datapoint values. The system was slow by today's standards, but at the time the additional cost and complexity of networking on PC machines was such that it was common that Macs were the only networked personal computers in an office. Due to narrower streets and higher cost of copper, European cables had thinner wires and used closer spacing. The SCC cost about $5 more than a UART, but offered much higher speeds of up to 250 kilobits per second (or higher with additional hardware) and internally supported a number of basic networking-like protocols like IBM's Bisync.

SCSI-1, SCSI-2 and SCSI-3 are signaling protocols and do not explicitly refer to a specific rate. Variometers are often used. The radiation resistance of short antennas can be very low, as low a few ohms in the LF or VLF bands, where antennas are commonly short and inductive loading is most needed. Copper was already in use in telegraph cables and this is the very best conductor available short of using silver. At the rate of 45.45 (±0.5%) baud - considered speedy at the time - up to 25 telex channels could share a single long-distance telephone channel by using voice frequency telegraphy multiplexing, making telex the least expensive method of reliable long-distance communication. Decreasing R means using more copper and a more expensive cable. A more engineer friendly rule of thumb is that the approximate requirement for spacing loading coils is ten coils per wavelength of the maximum frequency being transmitted.

This is mainly due to the low value of leakage through the cable insulator, which is even more pronounced in modern cables which have better insulators than in Heaviside's day. The elevated currents waste energy by heating the wire, and can even overheat the transmitter. When so loaded the antenna presents a pure resistance to the transmission line, preventing energy from being reflected. Monopole and dipole radio antennas are designed to act as resonators for radio waves; the power from the transmitter, applied to the antenna through the antenna's transmission line, excites standing waves of voltage and current in the antenna element. This is what was happening in the cable industry, the local franchise authorities had the power to control which cable systems were granted access to their area. To reduce power lost in dielectric losses, the coil is often suspended in air supported on thin ceramic strips. Another type of loading coil is used in radio antennas. Because twisted pair is a balanced format, half the loading coil must be inserted in each leg of the pair to maintain the balance.

This increases the flux linkages, without which the number of turns on the coil would need to be increased. HFC makes two-way communication over a cable network practical because it reduces the number of amplifiers in these networks. The sheer number of overhauls caused roadways and sidewalks to be torn up which affected pedestrian and vehicular travel while adding extra expense to the endeavor. Changes in the frequency range used for upstream signals have been proposed: a mid split which uses frequencies from 5 to 85 MHz for the upstream, a high split which uses a range from 5 to 205 MHz, and an ultra high split with several options that allow for ranges of up to 5 to 684 MHz. Each is crafted out of a sheet of metal folded 3,526,735 times by mystic monks until they have honed the perfect flatedged blade. The fiber optic network extends from the cable operators' master headend, sometimes to regional headends, and out to a neighborhood's hubsite, and finally to an optical to coaxial cable node which typically serves 25 to 2000 homes. One of the primary technical challenges was to sufficiently insulate the submarine cable to prevent the electric current from leaking out into the water.
