The Taoglas Comet MA585 is a low profile, puck style, screw mount antenna. The MA585 contains one 5G/4G high-performance antennas for use in MIMO cellular systems and one GNSS antenna. Through innovative antenna engineering techniques, it covers all worldwide cellular frequencies from 600MHz to 6GHz and GNSS Bands, BeiDou, GPS and GLONASS with stable gain and high efficiency, usually difficult to achieve in smaller style antennas. 

A key differentiator of the Comet MA58x series is its ability to maintain strong performance when mounted directly on metallic enclosures. Competing antennas typically experience severe efficiency losses in the lower 5G/4G bands (617–960 MHz), but the Comet was designed specifically to overcome this challenge. Leveraging Taoglas’ proprietary all-metal PIFA design and advanced bandwidth optimization techniques, the MA58x Series delivers consistently higher efficiency and more reliable radiation even when installed on metal housings with feed cables routed inside. 

This robust design ensures dependable connectivity where other low-profile antennas fail, making the Comet series particularly well-suited for fleet and transport telematics, public safety, gateways, and other missioncritical applications that demand both a discreet form factor and reliable operation on metallic or equipment surfaces. 

Typical Applications Include: 

- Telematics, Transport and Fleet Management 

- Gateways and Routers 

- Digital Signage and Point of Sale Terminals 

- First Responder and Emergency Services 

The Comet has been designed to be permanent mount/screw mount. This allows it to be utilized and installed in applications where a strong and secure mechanical attachment is required, ensuring reliable performance even in high-vibration or harsh environments. The GNSS and cellular MIMO connections utilize 2m of TGC1.5DS coaxial cable with SMA(M) connectors as standard. Customized cable and connector versions are also available upon request.

> **Installation Instructions** a **Comet MA58x Series** Low Profile Permanent Mount Combination Antenna ee **A Introduction** ~~L——=~~ The **Taoglas Comet MA58x Series** is a low-profile, puck-style, screw-mount antenna that integrates two high-performance 5G/4G MIMO cellular elements and one GNSS element. Covering all worldwide cellular frequencies from 600 MHz to 6 GHz, along with GPS, GLONASS, and BeiDou bands, it achieves stable gain and efficiency that are typically difficult to realize in such a compact 101 × 101 × 20 mm form factor. **Electrical Safety** The Comet can contains an active GPS/GNSS antenna. Rated voltage: 1.8-5.5VDC Rated current: 10mA maximum **The supply to this device must be provided with overcurrent protection of 1A maximum. Power consumption @ 1.8-5.5V ; 10 mA** 

## ~~——=—_~~ **B Mounting & Location** ~~—~~ 

Secured via a Ø12mm diameter threaded mounting stud, The Comet is recommended to be fitted by drilling a Ø13mm hole will need to be drilled in the roof or enclosure surface. 

When mounting on a vehicle roof panel ensure to mount on a flat surface, and measure for a central position. Care should be taken to mount the Comet antenna as far as possible from other roof-mounted features such as the aircon unit, light bar etc. 

**Sealing** In order to ensure that the installation is properly sealed against the mounting surface care must be taken regarding curvature of the mounting panel. It is highly recommended to install the antenna on a clean, flat and level surface. Afer installation the compression of the foam gasket and adhesive against the mounting panel should be checked and a small bead of neutral cure silicone sealant can be applied around the periphery of the enclosure if required. ~~COL~~ **C** ~~=—e—“—sS—S—S—S—‘CS~~ **Surface Preparation** ~~=~~ When preparing to drill the hole, mask the area around the hole position to protect the surface. If an existing OEM antenna mounting hole is not present, drill a pilot hole and increase the hole size to Ø12mm (0.472”). Ensure the drill bit does not contact the headliner. Then deburr and clean the area around the hole carefully removing all waste. 13mm 

Remove paint and primer from under panel surface to ensure adequate earth contact by washer and nut. Apply petroleum jelly or paint around cut edge of the hole to prevent corrosion

## **D** ~~COL~~ 

## **D Adhesive Foam Gasket** 

On the underside of the antenna there is a 3M adhesive foam gasket. Peel away the 3M adhesive protection and feed the cables through the hole. Position the antenna over the hole and press down onto the panel with pressure. This adhesion will ensure the antenna is securely mounted and will also allow for extremely minimal curvature on the roof of a vehicle.
