Overview

The Taoglas Olympian III MA181.A.001 is a 3-in-1 permanent screw mount antenna for vehicles and outdoor assets. It combines an active multi-constellation GNSS element with two 5G/4G MIMO elements covering 600-6000 MHz, including 5G FR1 bands and 3G/2G fallback. It is housed in a compact Ø59.45 x 70 mm IP67, IK08 ASA enclosure, and each element has a 1 m cable terminated in SMA(M). It suits telematics, digital signage and remote monitoring installations where positioning and cellular MIMO share one mounting point.

  • 3-in-1 combination: 1x active GNSS plus 2x 5G/4G MIMO elements
  • Cellular coverage 600-6000 MHz: worldwide LTE, many 5G FR1 bands, 3G/2G fallback
  • Multi-constellation GNSS: GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS, L-Band
  • GNSS LNA with up to 31.3 dB gain and under 3.1 dB noise figure
  • IP67 and IK08 rated UV-resistant ASA enclosure, Ø59.45 x 70 mm
  • 1 m RG-174 (GNSS) and 1 m TGC-1.5DS (cellular) cables with SMA(M) connectors
  • Designed to perform on both metal and plastic mounting surfaces
  • One mounting hole replaces three separate antennas, which simplifies vehicle and cabinet installs

The Taoglas Olympian III MA181.A.001 puts three antennas under one low-profile radome: an active GNSS antenna and two 5G/4G MIMO cellular antennas. It is built for external use on vehicles and outdoor assets that need location and cellular MIMO connectivity through a single hole. The unit stands 70 mm tall and 59.45 mm in diameter. It mounts from the inside of the host enclosure, and its small thread suits installations where space is tight.

The two cellular elements cover 600-6000 MHz. That range spans worldwide LTE bands, many sub-6 GHz 5G FR1 bands (including n71, n77, n78 and n79 frequency ranges) and 3G/2G fallback. Taoglas designed the antenna to suppress cable radiation, so performance holds whether it is mounted on a metal box or a plastic structure. Taoglas recommends a minimum 1 m cable length for stable performance. Each cellular element is omnidirectional and linearly polarized, handles up to 10 W input, and reaches up to 6.01 dBi peak gain.

The GNSS element is right-hand circularly polarized and covers GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS and L-Band frequencies. Its integrated LNA provides up to 31.3 dB gain with a noise figure below 3.1 dB. Out-of-band rejection is 70 dB below 1 GHz and 60 dB above 1.7 GHz. The element runs from 1.8-5.5 V at 9 ± 3 mA.

The UV-rated ASA enclosure resists vandalism and carries IP67 and IK08 ratings. An integrated rubber O-ring keeps water from getting under the antenna. It operates from -40°C to 85°C and is RoHS and REACH compliant. The GNSS lead is 1 m RG-174, and the cellular leads are 1 m TGC-1.5DS, all terminated in SMA(M). The Taoglas datasheet documents full per-band performance.

Ideal for

  • Fleet telematics units that need GNSS positioning and 5G/4G MIMO through one roof hole
  • Digital signage and kiosks connecting over cellular in outdoor locations
  • Smart metering and remote monitoring cabinets on metal or plastic enclosures
  • Mobile routers and gateways in service vehicles and transit
  • Outdoor asset tracking with multi-constellation GNSS

Questions buyers ask

Which satellite systems does the MA181.A.001 GNSS element support?

The datasheet lists GPS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b/E6), BeiDou (B1C/B1I/B2a/B2b/B3), QZSS, IRNSS, SBAS and L-Band (1542 MHz) frequencies. The element is RHCP with an integrated LNA of up to 31.3 dB gain.

Does the GNSS element need power?

Yes. The active GNSS element operates from +1.8 to 5.5 V and draws 9 ± 3 mA.

Can it be mounted on a metal vehicle roof or metal enclosure?

Yes. Taoglas designed the antenna to suppress cable radiation so it performs on both metal and plastic structures. It mounts from inside the host enclosure with a screw thread and has an O-ring seal against water ingress.

What cables and connectors are included?

The GNSS element uses 1 m of RG-174 cable, and each of the two 5G/4G elements uses 1 m of TGC-1.5DS cable. All three are terminated in straight SMA(M) connectors.

Which cellular frequencies does it cover?

The two MIMO elements cover 600-6000 MHz. This includes Band 71 (617-698 MHz), low-band LTE, mid-band, 2300-2690 MHz, 3300-5000 MHz (bands 42, 48, 77, 78, 79) and 5150-5925 MHz, plus 3G/2G fallback.
