Some of the major factors which influence shielding effectiveness of flexible coaxial cable assemblies are as follows:

Impedance in a coaxial product is a measurement of resistance to the flow of current. The unit of measurement is ohms.

There are many advantages to installing FTTH in your community. Fiber does not conduct electricity, has virtually unlimited bandwidth, is not affected by heat and cold, has a longer lifespan than copper or coax to name a few. Fiber installed by Connexion Technologies is incased in conduit - meaning extra protection against accidental damage.

A majority of coaxial cable types have their origins in the military world and are identified as RG (Radio frequency,Goverment ) Some common types of RG cable are RG6, RG59, RG62, RG58, RG142, RG174, RG188 and RG316.

The primary use of a 75Ohm cable is to transmit a video signal. One common application is television signals over cable, sometimes called signal feed cables and often used with an F Type connector. Another application is video signals between components such as DVD players, VCRs and Receivers, commonly known as audio/video (A/V) cables. In this case, BNC and RCA are the most commonly used connectors.

The camera LED shows a permanent green signal after start-up and does not flash red/green as described in the manual.

Coaxial cable is pure copper or copper-coated wire surrounded by insulation with an aluminum covering used to transmit television, telephone and data signals. Fiber optic cable is also used to deliver the same types of signals but can carry much wider bands of frequencies. It's made of very thin, pliable tubes of glass or plastic.

A coaxial digital audio cable uses copper wiring as its signal conductor and dual-RCA jacks as connectors. An optical digital audio cable uses fiber optic wiring as its conductor and dual Toslink connectors. Both types of cables perform the same function; however, an optical digital audio cable is immune to external interference because its conductor is non-metallic.

Yes, our coaxial connections are bi-directional, meaning they will pass both a receive and transmit signal.

dB/100 ft. Q. I have just installed 6 AU-E's and sectoral antennas on my tower, and when I use best AU feature, some of my SU's can "see" 2 or 3 antennas, and some can see all 6. Why? I thought the sectoral antennas did not receive and transmit through the back of the antenna! All antennas radiate transmitted energy in all directions around the antenna, but the design of any directional antenna is such that more of the energy is "focused" in the designed direction.

There are several reasons, all dealing with the extra shielding on these cables. One reason is that the double braid makes the OD of the cable braid larger than the ID of the crimp sleeve. A second reason is, if the crimp sleeve will fit over the braid on the connector, the amount of pressure required to crimp, or specifically, to force the crimp tool to its fully closed position, allowing it to open, is excessive.

The array is powered by a 120 VAC, with a 1U battery backup in the base station hut. We do not require any other lines to be run up the tower other than power.

Yes, but you will need an RF modulator (radio frequency modulator). RF modulators are available at many electronics stores, including RadioShack.

No, you will need a VCR that will act like a cable box tuner or you will need a special converter/tuner.

Some of the common connector types used on coaxial cable are BNC, SMA, SMB, SMC, MCX, TNC, N, SMC, MMCX, F, and UHF. These connector types come in male and female versions.

Double shielding in a coaxial cable indicates two layers of outer conductor shielding. Often one layer is a metallized foil while the other layer is a metallic braid. These two layers decrease the leakage of energy from the cable.

DSL provides a dedicated service over a single telephone line. Cable modems offer a shared service over a cable network. Customers have the opportunity to choose a package and speed that match their needs. There are more packaging choices available with DSL, including services that a business may desire such as static IP addresses.

The core standards that describe the ATSC digital television system are A/52, Digital Audio Compression Standard (AC-3, E-AC3), and A/53, ATSC Digital Television Standard. These documents, and all other ATSC standards are available for download at no charge from the ATSC Web site, http://www.atsc.org/standards.html.

Impedance is defined as the vector sum of resistance and reactance which limits the current flow in an AC circuit. When dealing with a transformer, impedance indicates the current limiting effect should you have a short circuit on the secondary. Expressed as a percentage and usually designated as %IZ, impedance along with X/R ratio is used for coordination of fuses and/or circuit breakers. It is also used for calculating the proper interrupting rating of overcurrent protection devices.

The DCT6412 does not have an RF modulated output. The product was designed to match the growing trend in newer TVs for alternate inputs. The product supports component (HD), composite, S-Video, DVI, and 1394 video outputs. For installations to TVs that have only an RF input, a VCR hookup or external RF Modulator can be used. The RF modulator converts the baseband (composite) video and audio outputs of the set-top and modulates to RF channel 3 or 4 to the TV.

Your cabinet should have a model number and rating plate on the back, if there is no rating plate the cabinet will need to have the impedance measured by an engineer. We do not recommend using the cabinet until the impedance has been checked as it could damage both your amplifier and cabinet if either is used incorrectly. If your cabinet has a rating plate the impedance of the cabinet must match the impedance of the amplifier you are connecting it to.

Impedance is the load value that your speakers present to your power source — the amount of resistance they provide to the current flowing from your amplifier. While it's convenient to refer to a speaker's impedance as being a fixed value (say, 4 ohms) over a speaker's entire frequency range, the impedance typically varies with the frequency of the input signal. So when we say a speaker is a 4-ohm speaker, think of this rating as a useful approximation.

Coaxial describes the placement of the tweeter and subwoofer with respect to the design of a speaker. Coaxial is indicative of a speaker whose tweeter is directly in front of its subwoofer on the same axis. This saves room and usually allows the size of the speaker grill to be smaller while providing a wide frequency range.

The characteristic impedance of a transmission line or antenna can be defined in terms of the ratio of the voltage and current amplitudes, and the incident and reflected waves. VSWR has a similar general relationship in its definition. For communication systems, the 50-ohm characteristic impedance has become the adopted standard. It is the result of an industry compromise between maximum and minimum voltage and current handling of a transmission line.
