Product overview and engineering role
The SimtoLink suction-cup omnidirectional high-gain antenna sticks to a window or a smooth metal face for a short job: a drive test, a demo, or emergency communications, usually on a cellular or private-network terminal.
Band and polarization in the table have to match the terminal RF port. How clean and how curved the surface is decides whether the cup stays put. For a long outdoor stay, move to the through-hole bracket version. See the hardware specification.
Reliability and field fit
Heat and vibration let the cup leak and drop. In cold weather, warm the glass and check the sealing lip for age.
A metal body changes the pattern because it is the ground reference. After the antenna is on the vehicle, SimtoLink recommends an RSSI and throughput drive test, and the feeder should not hang and pull the connector.
Key hardware parameters
RF and mechanical ratings below are a typical build, for selection and for a tender clause. Another band, another cable length, or the through-hole bracket is a separate order; ask SimtoLink for the hardware specification and the installation and commissioning guide. Order codes in the family can differ. The nameplate and the papers in the carton govern.
| Parameter | Specification | Notes |
|---|---|---|
| Band | 698～2700 MHz (typical LTE) | Follow the order and the module |
| Gain | 5～9 dBi | Omnidirectional high-gain build |
| VSWR | <2.0 | Typical frequency points |
| Polarization | Vertical linear polarization (omnidirectional) | Mounting direction on the vehicle changes the pattern |
| Impedance | 50 Ω | SMA is common |
| Power | Limited by the module rating | Stay inside the regulatory EIRP |
| Ingress | IP65 | UV coating |
| Cable | LMR-200 | Low loss |
| Operating temperature | -44～71 ℃ | Outdoor |
| Mounting | Suction cup | Ground |
Typical applications
Four short-term jobs this cup antenna is bought for:
Field drive tests
An operator or a vendor drives a scan and compares terminal sensitivity without a permanent mount.
Commissioning and fault finding
A temporary lift in a weak spot, to see whether the fault is on the equipment side.
Emergency communications vehicles
A short deployment, without drilling the roof or waiting on a body conversion.
Demos and training
A glass wall in a classroom or a hall, with a link up in minutes.
Installation, grounding, and maintenance
- The surface has to be free of wax and dust. Press the cup on, then tug it to confirm it holds.
- Leave a service loop in the feeder so a door does not pinch the center conductor.
- In a thunderstorm, do not leave a temporary roof mount on open high ground. Take it down first.
- Before highway speed, check the cup and the cable ties so it cannot fall and injure someone.
- For a long assignment, move to a screw-on bracket and log VSWR and visual checks on a cycle.
Ordering, documentation, and support
SimtoLink can issue the hardware specification, outline drawings, a wiring table, and an example project for this antenna. Volume orders can include a sample review and inspection at the factory. Warranty and calibration follow the contract and the papers packed with the antenna.
