TEST RESULTS for FREQUENCY RANGES:
The results show good impedance matching performance within the 1.71 GHz to 2.50 GHz frequency range. The measured impedance of approximately 40.93 + j8.91 Ω remains relatively close to the nominal 50 Ω reference, indicating stable operation.
The VSWR values between about 1.32:1 and 1.67:1 and return loss values reaching −17 dB indicate low reflection levels and efficient signal transmission, confirming reliable RF performance across the evaluated band.
| Frequency range | Assessment | Rating | Technical performance details |
|---|---|---|---|
| 1.71 GHz – 2.50 GHz |
Good |
★★★ | RF performance evaluated across the 1.71 GHz – 2.50 GHz frequency range, showing stable impedance behavior during the frequency sweep. Around 2161 MHz, the measured VSWR is approximately 1.67:1 with a Return Loss close to −12.1 dB, indicating acceptable impedance matching within the evaluated band. At the lower frequency region near 1710 MHz, the VSWR improves to approximately 1.32:1 with a Return Loss of about −17.1 dB, showing better matching in that portion of the spectrum. The measured impedance near the reference point is 40.93 + j8.91 Ω, indicating a slightly inductive condition relative to the nominal 50 Ω system impedance. The Smith chart trajectory remains relatively compact around the central region, confirming stable RF behavior and controlled impedance variation across the evaluated frequency range. |
UL certification / rating of the flammability of the antenna housing (ABS):
- Test Method: UL-94
- The flame class of this ABS material is HB.
Cable is double-shielded, low-loss and very flexible. The cable-type is equivalent or better than LMR-100: Coax with black jacket has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174. The higher quality of the cable of this antenna translates into lower loss/better performance. These antenna cables are rated for outdoor use and are also suitable for indoor use. Recommended tightest continuous bend radius is 1.1 inch (28mm).
SMA Connector Characteristics:
- RP-SMA = Reverse Polarity SMA. Also known as SMA-RP, SMA-R, SMA RP, SMA R.
- RP-SMA and SMA gender is counter-intuitive: The gender is referring to the pins inside-not the threads. RP-SMA male have threads on the inside. More details regarding RP-SMA gender determination.
- RP-SMA-male and SMA are also called "plugs" and the respective female connectors are also called "jacks."
- RP-SMA and SMA are round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.
- Composition
- Connector Body: Brass, Gold Plated for low loss. Precision-machined.
- Center Contact: Beryllium Copper, Gold Plated
- Crimp Ferrule: Copper, Nickel Plated
- Insulators: PTFE
- We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
- SMA-male connector fits items that have an SMA (female) jack/connector.
- SMA male connector composition:
- 96% brass-copper alloy
- Less than 4% lead content (ROHS Compliant)
- 0.1% Chromium VI compound
- 0.01% (by weight) Cadmium / cadmium compounds
- 0.1% Mercury
- 0.1% PBBs
- 0.1% PBDEs
Conversion to Iridium Satellite Coverage: For all of our antennas that cover the GPS frequency 1.5GHz: We can convert the 1.5GHz GPS antenna to 1.6GHz in order to cover the Iridium (Satellite) frequency. This customization takes about 4 extra weeks in production and will increase the cost of the antenna by $1.75 per antenna.
Data Alliance's high-quality soldered terminations of SMA and MCX connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
