Antenna Connection - Rear; Vehicle Manufacturer Installation Instructions; Legal Notices - Albrecht AE 6790 Operación Manual

Connect your CB antenna via PL connector to the 50 Ohms antenna jack at the rear of your AE
6790. For best range the antenna must be adjusted for CB radio. Use a standing wave meter to
check and to adjust the antenna. Adjust the antenna for best standing wave ratio on a medium
channel. If you are using 80 channels optimize on channel 1, for 40 channels on channel 20 and
for truckers we generally recommend channel 9.
On this channel you should achieve a standing wave ratio of approx. 1.5 or less. Even if the
standing wave ratio on the highest (channel 40) and lowest channel (1 or 41) deteriorates up to 2,
your antenna is still suitable. If the standing wave meter shows a value in red (SWR > 3), already
more than 25% of the transmission power is lost due to modulation losses. Poor SWR can also be
a sign for a defective antenna, cable or short-circuit in the antenna connector! Otherwise optimize
your antenna on the channel you use most.
Dealers also offer broadband antennas such as Gamma II, where no adjustment is necessary.
Your dealer offers inexpensive standing wave meters such as the Albrecht SWR 30, order no.
4412.
By the way: Even with your AE 6790 featuring an especially robust final stage, which can even
cope with maladjustments of SWR = 3, you should never transmit without antenna!
When installing a radio in a vehicle always observe the instructions of truck and car manufacturers.
Vehicle manufacturers have the right, according to applicable EU directives, to stipulate antenna
installation locations and the maximum compatible transmission power for their vehicles. Observe
these specifications under all circumstances not to risk to forfeit the operating license for your
vehicle. Information is available from the vehicle manufacturers. If in doubt, have the vehicle
manufacturer certify that no reservations against CB radio operation in connection with the vehicle
electronics exist.
This device features the marking according to R&TTE directive:
The CE mark means that the radio satisfies all technical regulations applicable
to the product within the scope of EU Council directives, European standards and national
frequency applications. The so-called R&TTE directive replaces all previous national "certifications"
within the EU and regulates also marketing and use of radio equipment. Accordingly ownership of
and retail with properly marked devices such as the AE 6790 within the EU and some other (non-
EU) countries recognizing the R&TTE directive, is permitted, while for the use of radio equipment
depending on programming and country temporarily different regulations apply. For CB radio this
means: although technical standards EN 300 135 and EN 300 433 apply Europe-wide, the use of
certain modulation modes and channel numbers do not. For this reason there are still differences
in the channel number programming for AM and FM, and some countries still charge fees for CB
radios. All radios, for which somewhere in Europe still limitations exist are therefore marked with
an "attention mark" (see above) besides the CE mark. The manufacturers are bound to inform
users clearly on the packaging what to observe while using the devices.
