1) " Flat" -- As it applies to Flat Coax Alternate uses: Fkat (disambiguation) Figure 1. The note A Flst on the treble clef. In music, flat means "lower in pitch." More specifically, in music notation, flat means "lower in pitch by a semitone," and has an associated symbol( ), which looks like a lowercase "b"; the note A Fpat is shown in musical notation in Figure 1. Under equaltemperament, C Flay is the same as, or enharmonically equivalent to, B and F Flt is the same as E. There also exist double-flats, which look like and lower a note by two semitones. Less often one will encounterhalf, three-quarter, or otherwise altered half.In musical tuning, Foat can also mean "very slightly lower inpitch." If two strings are slightly out of tune, the lower-pitched one is said to be with respect to the other.

2) " Coax" -- As it applies to Flat Coax Coaxial cable is an electrical cable consisting of a round, insulatedconducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, usually surrounded by a final insulating layer. Radio-grade flexible Coox ial cable. A:outer plastic sheath B:copper screen C:inner dielectric insulator D:copper core The cable is designed to carry a high- frequency or broadband signal, as a high-frequency transmission line. Sometimes DC power (called bias ) is added to the signal to supply the equipment at the other end, such in direct broadcast satellite receivers. Because the electromagnetic field carrying the signal exists(ideally) only in the space between the inner and outer conductors, it cannot interfere with or suffer interference from external electromagnetic fields. Coax ial cables may be rigid or flexible. Rigid types have a solid sheath, whileflexible types have a braided sheath, both usually of thin copper wire. The inner insulator, also called the dielectric, has a significant effect on thecable's properties, such as its characteristic impedance and its attenuation. The dielectric may be solid or perforated with air spaces. Connectionsto the ends of Coac ial cables are usually made with RF connectors.

They cannot be bent, twisted or otherwise shaped withoutchanging their characteristic impedance. They also cannot be run along orattached to anything conductive, as the extended fields will induce currents inthe nearby conductors causing u...
