The Alpine KAE-242DA antenna<\/strong> is an adhesive, asymmetrical foil antenna designed to receive Band III and L-band signals. It includes a 3.5 m cable and a right-angle female SMB connector. The connected receiver supplies power to the antenna through this connector.<\/p>\n

Purpose and product selection<\/h2>\n

This model receives signals in two separate frequency bands. The Band III range<\/strong> covers 170-240 MHz, while the L-band range<\/strong> covers 1452-1495 MHz. These are two distinct bands rather than one continuous frequency range extending between the stated limits.<\/p>\n

Three points are particularly important when deciding whether this antenna is suitable. The receiver must operate within the specified frequency bands, provide the required power, and have a compatible connector. Suitability for installation in a particular vehicle cannot be established from the available information, so check the intended mounting position, the complete cable route, and the receiver connection before ordering or installing it.<\/p>\n

Foil construction<\/h2>\n

The foil antenna<\/strong> occupies an area measuring 40 \u00d7 170 mm. Its adhesive backing allows it to be attached without using a separate antenna bracket.<\/p>\n

The antenna combines black and transparent<\/strong> sections. This makes it possible to consider how the different parts of the antenna will look against the chosen mounting surface before fixing it permanently in place.<\/p>\n

Signal reception direction<\/h2>\n

The omnidirectional design<\/strong> means that the antenna does not have to be pointed towards one specific signal direction. This simplifies position selection when signals may reach the antenna from different directions. The description of the antenna as omnidirectional does not remove the need to choose a suitable mounting area and plan the cable route carefully.<\/p>\n

Cable and connector<\/h2>\n

A 3.5 m low-loss cable<\/strong> connects the antenna to the receiver. When planning the installation, use the actual routed distance rather than only measuring a straight line between the two components.<\/p>\n

The end of the cable is fitted with a right-angle female SMB connector<\/strong>. Its angled form reduces the amount of space required directly behind the connection. This is useful where the cable needs to turn to the side immediately after reaching the receiver socket.<\/p>\n

The female connector must mate with the corresponding male SMB part. Checking only that both connections are described as SMB is not sufficient, because connector gender also matters. An input with a different connector type, form, or gender is not suitable for a direct connection.<\/p>\n

Power supplied by the receiver<\/h2>\n

The antenna requires 5-12 V phantom power<\/strong> supplied by the connected receiver. Its specified current consumption is 30 mA. The receiver’s antenna connection must therefore be capable of providing these power conditions.<\/p>\n

Phantom power travels through the antenna connection, so a separate power connector is not required. If this supply is controlled through a receiver setting, it must be enabled as part of the installation.<\/p>\n

A physically compatible SMB connection alone does not guarantee operation. The receiver must also deliver power within the specified voltage range. A passive antenna input that provides no such supply does not meet the powering requirements of this model.<\/p>\n

Planning the installation<\/h2>\n

Before removing the adhesive backing, hold the antenna temporarily against the proposed mounting position. Confirm that the flat, clean, and dry surface can accommodate the entire 40 \u00d7 170 mm element. This trial placement lets you assess its 40 mm width, 170 mm length, and final orientation before committing to the position.<\/p>\n

Because the antenna is asymmetrical, the selected area must provide room for the complete foil outline. It is not enough to consider only the point where the cable leaves the antenna. Make sure there are no obstructions within the required area, and decide which way the cable will run before attaching the antenna.<\/p>\n

Measure the full 3.5 m route from the antenna to the receiver, including bends, concealed sections, and any indirect routing. Check that the right-angle connector will face in a useful direction once connected. Allow enough room for gentle curves so that the cable does not need to be stretched or bent sharply near either the antenna or the connector.<\/p>\n

The 50-ohm impedance<\/strong> is another system-matching requirement. Consider it together with the connector type, supported frequency bands, and phantom-power requirements. Reviewing all of these points helps prevent selection based only on a connector that looks externally similar.<\/p>\n

FAQ<\/h2>\n

What should I check for receiver compatibility?<\/h3>\n

Check that the receiver supports the 170-240 MHz Band III and 1452-1495 MHz L-band ranges, has an input compatible with the right-angle female SMB connector, and supplies 5-12 V phantom power. The system’s 50-ohm impedance is also important.<\/p>\n

Does the antenna need a separate power cable?<\/h3>\n

No. The receiver must supply power through the antenna connection. Its output must provide 5-12 V and support a 30 mA load.<\/p>\n

What should I check before attaching the antenna?<\/h3>\n

Temporarily position the antenna in the chosen location before exposing the adhesive. Consider its dimensions, asymmetrical shape, cable direction, and the entire route to the receiver.<\/p>\n

Will the cable reach the receiver?<\/h3>\n

Compare the 3.5 m cable length with the actual planned route. Include every bend and concealed section rather than measuring only the straight-line distance.<\/p>\n

Why is the right-angle SMB connector important?<\/h3>\n

It allows the cable to turn to the side immediately at the connection. However, the receiver connection must still have the correct SMB type and gender.<\/p>\n

Does the antenna need to point towards one transmitter?<\/h3>\n

No. Its omnidirectional construction means that it does not need to be oriented towards one particular direction.<\/p>\n","protected":false},"excerpt":{"rendered":"
