On this channel you should obtain a SWR of approx. 1.5 or less. If the SWR deteriorates on the
highest (Channel 40) and lowest (Channel 41) channels up to a value of 2.5, then your aerial is
still acceptable. SWR above 3 is too bad for good communication range. A bad SWR may also
indicate that there is perhaps an installation error or missing ground. Problems may be caused
through missing ground, especially in boats and motor homes with fiber glass body. For these
cases, Albrecht offers a special connecting cable with matching box as “artificial ground” (AKM 27),
or ground less antennas like GL 27.
Some antennas, like “Gamma II” are broadbanded and do not need any retuning during
installations.
Even if your AE 6890 has a heavy duty transceiver with a high-level output stage which can
even withstand mismatching of SWR=3, you should still never transmit without an antenna!
Installation instructions of the vehicle manufacturers
European directives allow the car manufacturers to decide, where, or even whether or not private
radio transceivers may be operated in their cars, this is also valid for antenna installations. Please
install Your mobile CB station only in accordance to car manufacturer’s installation instructions.
Legal Information
CE-Marking and Conformity with European Standards
This device is provided with the from the R&TTE Directive required identification:
The CE sign means, that this radio achieves the basic requirements of the new
european regulations. The so-called R&TTE Directive displaced all earlier national “type approvals”
in the EU and also regulates the bringing into circulation and the use of radio installations. So the
ownership and the trade with proper labelled devices such as the AE 6890 in the EU and some
other (not EU-) countries, who accept the R&TTE Directive, allowed, while for the use of radio
installations there are still different rules, depending on the programming and the country. For CB
radios this means: the technical standards EN 300 135 and EN 300 433 are valid Europe-wide, but
not the use of specific modulation types and channel numbers. So there still are differences in the
programming of the channel numbers in AM and FM and still some countries charge license fees
for CB radios. All radios, for which there are somewhere in Europe restrictions, have beside the CE
sign also an “Alert Sign” sign (see last page). All manufacturers have been obliged to inform their
users noticeable on the package and in the manual, what they have to follow while using the
device.
This is in so far understandable, because the frequencies were used for different objects in every
country and so it takes a while to harmonize all those different frequencies.
The AE 6890 achieves the for CB radio harmonised European radio-standards EM 300 433-2 and
EN 300 135-2 as well as EN 301 489-13 for the electromagnetic compatibility and EN 60 950-1 for
the electric safety. So this device does not transmit any harmful radio interference and is on the
other side also immune to radiations from other devices, if it is used as intended. In generally this
is the case, if you do not connect any cables to the microphone- and loudspeaker jack which are
longer than 3 m.
Our recommendation: if you use your radio with the AM-programming, please consider the
licence conditions mentioned above seriously! You risk, if you are found that You have a wrong
programming and you cannot show a licence, a possible penalty or other sanctions. It is also
important that you register in your home country, if there still is a registration necessary. Users
within UK are only allowed to use 40 FM and 40 FM with UK channels.
