MTA automotive electrical components

In the field of complementary products, MTA supplies many noteworthy solutions. These primarily include various types of housings. The first type is single holders, e.g. wire-mounted, ideally suited for protecting circuits added to a vehicle installation during modifications (e.g. when installing an additional audio amplifier or an onboard computer). In more complex cases, a more practical solution is to use fuse boxes capable of accommodating up to 16 blade fuses. Such boxes feature mounting holes and transparent covers to facilitate inspection and possible identification of blown elements. If installation is to be carried out outside the cabin (e.g. in the engine compartment), special sealed enclosures will provide even better conditions.

In addition, MTA also supplies single high-current holders with covers, covers only, standard electrical connectors, seals (housing accessories), so-called battery terminals and many other related accessories.

Car Antennas

It is hard to imagine a vehicle without any form of wireless communication – whether it is receiving radio stations, communication via the cellular network, or an Internet connection. In many cases, particularly in public transport, onboard WiFi networks are also provided. There is also often a need to improve the reception of signals from global geolocation systems (GNSS). MTA offers antennas for all of these applications. The first group includes standard radio antennas adapted to the bands used in analogue transmission (AM and FM) and the increasingly popular digital standard (DAB). Most of the supplier’s products support at least two bands. Listed below are several forms these antennas may take: roof-mounted (traditional and “shark fin” type), telescopic (including electrically extendable), and flat (adhesive-mounted inside the cabin, wheel arch, etc.).
 

Achieving optimal cellular network connectivity is not only a matter of driver convenience, but also a prerequisite for the proper operation of many systems, e.g. centralized fleet management, which makes it possible to monitor each vehicle. Therefore, many MTA antennas are designed for data transmission using LTE and 5G technologies, or for improving the reception of satellite signals (GPS). In this field as well, MTA solutions are multiband and adapted for roof mounting to minimize signal attenuation by the vehicle body.
 

In this field, it is also worth mentioning articles adapted to operate in the UHF and VHF spectrum, which may be used for communication or reception only on open frequencies. The range also includes antennas for WiFi and Bluetooth modules, which are often used in minibuses, camper vans, and wherever improved network connectivity is required. The supplier’s connection cables complement the portfolio, factory-fitted with connectors in the most popular formats, such as DIN, Fakra, SMA, SMB, FME.

Car Audio

MTA offers a somewhat narrower, but still comprehensive, assortment in the field of car audio products. Here, three product groups should be highlighted. The first is speakers – a component often replaced due to wear of factory HiFi components, or as part of an upgrade. MTA supplies speakers with diameters from 87mm to 165mm, operating in standard frequency ranges, from 60Hz to 20kHz (all feature a two-way design), with power ratings up to 100W. The sets include a pair of units, all characterized by the typical 4Ω impedance. In addition, the TME catalogue offers universal speaker grilles (square and round).
