Open points to freeze before an alternate is accepted
A shorter bill is useful only when every blank is labeled mandatory, preferred, or unknown. The table is a handoff, not a sustainability statement and not a coverage model. GPS L1 at 1575.42 MHz belongs on a GNSS patch brief. It does not fill a cellular indoor band list.
| Open point | Write this | Do not accept this substitute |
|---|
| Frequency range | Each window in MHz, such as 700, 850, 1900, 2100, plus any public-safety slice | The word broadband with no numbers |
| Connector | 4.3-10, N-type, or the DIN variant, with gender | A photo of a silver shell |
| PIM | Limit and method, often discussed near -150 dBc at 2 x 43 dBm | A brochure adjective such as low PIM |
| Pattern and mount | Corridor directional or ceiling azimuth, and tile, wall, or hard-cap mount | A single indoor antenna used for every floor plate |
Impedance stays 50 ohm unless the drawing says otherwise. Insertion loss of a splitter and coupling of a tap are dB figures. Donor gain, if a donor is even on this indoor sheet, is dBi and lives on a different line. Return loss or VSWR, for example 1.5:1 at the band edge, needs the test port. Power rating of a combiner is not the remote power draw. If a remote is in the same package, say whether it wants Power over Ethernet or a local supply, and write the watts.
MIMO, when the indoor service is more than one path, needs 2x2 or 4x4. Channel width of 10 MHz or 20 MHz is a radio setting. The passive hardware still has to pass it. Polarization for most in-building service antennas is vertical or slant. That note is different from RHCP on a GNSS patch, so do not copy the GNSS sentence onto this sheet.
Fiber appears only when the head-end is not in the same closet as the first remote. Then wavelength and optical budget are required. Single-mode at 1310 nm and multimode are different plants. Leave the cell blank rather than picking one because a catalog photo shows a yellow jumper. Rack unit count of the head-end is irrelevant to a ceiling antenna and should not be used to pad this handoff.
Choices that remain buyer decisions
A managed remote can show alarms. An unmanaged passive tree cannot. If the buyer has not chosen, mark the cell unknown. An OEM-coded indoor antenna may track a host vendor note. A compatible antenna may be allowed with a written deviation. New versus refurbished is a condition cell: a refurbished panel can meet the band and miss the PIM number. Do not let a lower unit price erase that cell.
Calibration traceability and measurement accuracy belong next to any numeric PIM or VSWR limit. Connector mating cycle belongs next to jumpers that will be disconnected during test. Ingress protection is usually blank indoors and required on a donor that this page may have excluded. Environmental rating of a ceiling puck is not inherited from a rooftop panel.
Sourcing scenario: a contractor offers to swap every corridor antenna for a cheaper ceiling puck. Background is a hospital wing with long halls and a PIM note of -150 dBc at 2 x 43 dBm already written by the owner. Process is to keep the directional pattern and the PIM method as mandatory, and to treat the puck as an alternate only where the owner marks the hall as acceptable. Result is a deviation list. The cheaper puck is not silently accepted for the whole wing. LinkScope Sourcing 30 can forward that list. It cannot sign the owner acceptance.
Also record quantity unit (antennas, splitters, or jumpers), US destination, requested timing, and whether freight and connectors are inside the price. A sample of two antennas is not the floor count. Optional budget needs currency and a per-unit or whole-order basis. Supplier preference of high-end, mid-range, budget, or undecided is the buyer stance, not a rating. Evidence to request: current datasheet, mechanical drawing, and the PIM setup. 47 CFR Part 2 Subpart J is a question for an active radio in the package, not an approval of a passive puck. Read the enterprise project page when the hop leaves the building, and the inquiry names when the bill is still a family label.
