What the desk does at each quote stage
A service name is not a laboratory. The matrix below is the work a buyer can expect from this desk when a gps glonass internal antenna or a related DAS line is the subject. Public carriers stay context: GPS L1 is 1575.42 MHz, and GLONASS L1 sits near 1598 to 1606 MHz. Those numbers frame the question. They are not a gain figure this site measured.
| Stage | Desk action | What the desk will not invent |
| Intake | Read frequency range, 50 ohm impedance, connector, polarization, quantity, destination, and requested timing | A street address, a published phone line, or a factory audit |
| Match | Send the same sheet to more than one maker when the brief allows it | A claim that any reply is OEM-coded or compatible until the maker writes the model |
| Normalize | Separate sample quantity from production quantity, and per-unit budget from whole-order budget | A percentage saving, a stock promise, or a ship date |
| Handoff | Return datasheet revision, VSWR method, and listed exclusions beside each price | Coverage prediction, installation, or FCC equipment authorization |
Impedance is written as 50 ohm unless the drawing says another value. Gain in dBic and axial ratio stay on the datasheet of the exact ceramic. VSWR, often requested as 2.0:1 or tighter, is only comparable when the ground-plane size is named. Connector mating cycle is a field for a pigtail that will be unplugged, not a slogan.
Power over Ethernet appears when the brief is an active remote rather than a patch. Insertion loss and return loss appear when the brief is a splitter or a jumper. The desk keeps those families on separate lines so a dB loss is not added to a dBic gain. Environmental rating is requested for an outdoor donor and left blank for a board-level patch unless the buyer adds it.
Sourcing scenario for the desk itself: a purchasing clerk forwards a photo of a square ceramic and asks for a ranked factory. Background is a 25 mm keep-out and a US warehouse destination, with quantity still marked as a range. Process is to refuse a ranking and to ask for frequency range, RHCP or another polarization call, connector family, and whether the lot is a sample. Result is a sheet factories can answer. The clerk still chooses the maker.
Two commercial readings stay visible. An OEM-coded radio may follow a host-vendor support note more closely. A compatible indoor antenna may be acceptable when the buyer writes the deviation. New hardware has a cleaner test file than refurbished hardware, which can still match the band and fail a PIM check. The desk records both readings. It does not merge the prices. High-end, mid-range, budget, or undecided is the buyer preference written on the form, not a score assigned here.
Evidence the desk can request, and cannot issue: a current datasheet, a mechanical drawing, the PIM or VSWR method, and calibration traceability of the meter when the limit is numeric. 47 CFR Part 2 Subpart J is the citation a buyer can use to ask whether a finished transmitter needs FCC equipment authorization. The citation does not approve a patch, a jumper, or this website. ISO 9001, if a factory offers it, is a quality-system document to read, not a product test. Measurement accuracy without a method is left as an open question.
