MULTI-LINE COMPARISON
Traceable lines
coaxial cable factory
A coaxial cable factory reply is useful when every BOM line keeps its own construction, length, and evidence. LinkScope Sourcing 24 uses this workflow so a drop reel, a jumper, and a connector kit are not collapsed into one cell.

Scope that must stay attached to each line
| Line | What the factory must price | What stays out of that cell |
|---|---|---|
| Bulk RG6 | Conductor, shield, jacket, reel or cut, attenuation rows | Connector labor, splitters, amplifiers |
| Jumper | Finished length, connector series, assembly return loss | The bulk reel rate, even if the cable print matches |
| Spare connectors | Series, plating, tool, mating-cycle statement | A claim that any F fitting fits any port |
Impedance on these lines is typically stated as 75 ohm nominal, with the center recorded as 18 AWG / 1.02 mm when the print is an RG6-style drop. Frequency range still has to be the range you operate. Ask for attenuation at 50 MHz, 220 MHz, 550 MHz, 1000 MHz, and 2150 MHz, in dB per 100 m or dB per 100 ft. VSWR or return loss, if you require it, is requested at that range for the offered assembly, and insertion loss stays on the jumper line. A catalog curve for a different shield stack is marked as missing evidence.
OEM-marked connectors and compatible connectors can both appear. The workflow records which one the specification allows and which test sheet arrived. It does not treat the word compatible as a pass, and it does not treat an OEM mark as proof without the document for that lot.
Evidence questions before a deviation is accepted
- Does the datasheet name the same construction code as the quotation line?
- Are attenuation units dB/100 m or dB/100 ft, and at which megahertz rows?
- Is the jacket rating the one the route requires, with the supplier document cited?
- If the center conductor changed from solid copper to copper-clad steel, is that written as a deviation?
- If the offer is surplus cable, are remaining length, storage, and lot sweep status stated?
- Are freight, duties, and the destination outside the unit rate, in a visible commercial line?
Insertion loss of a 1 meter jumper and attenuation of a 100 meter drop answer different questions. Keep both numbers if both lines exist. A single averaged loss hides the line that failed the link budget.
Standards pages, including a TIA premises overview, can suggest which question to ask. They do not replace the factory document for the construction on the line. FCC equipment authorization, when it applies, belongs to active devices on other BOM rows, not to a passive reel, unless the supplier shows why that file covers the cable.
Open choices stay open: shield coverage percent, plenum versus riser, and whether connectors are factory fitted. Accepting an alternative means those choices were written down, not that the lowest unit rate won.
Each line should be able to show 75 ohm impedance, its frequency range, return loss, insertion loss, and VSWR when the assembly drawing uses that term. Connector mating cycles and an ingress-protection code belong on the connector line, not on the bulk reel cell. The 2026-10-27 question list does not fill those cells.
