RX-AM4SF
---------------------------------------------------------------------------------------------------------------------------------------------------
Instruction Manual
Antenna connection:
1. It may be utilized as the direct connection point for the radiating whip antenna.
2. It can bear the connection of the central wire of a 50
Ω
coaxial cable. Be sure that the braid is
welded to the ground in a close point.
Antenna
1. A
whip
antenna, 16,5 mm long and approximately 1 mm dia, brass or copper wire made, must
be connected to the RF input of the receiver.
2. The antenna body must be keep straight as much as possible and it must be free from other
circuits or metal parts (5 cm minimum suggested distance.)
3.
It can be utilized both vertically or horizontally, provided that the connection point between
antenna and receiver input, is surrounded by a good ground plane.
N.B
:
As an alternative to the a.m. antenna it is possible to utilize the whip model manufactured by
Aurel (see related Data Sheet ed Application Notes).
By fitting whips too different from the described ones, the EEC Certification is not assured
.
Other components:
1. Keep the receiver separate from all other components of the circuit (more than 5 mm).
2. Keep particularly far away and shielded all microprocessors and their clock circuits.
3.
Do not fit components around the 50 Ohm line. At least keep them at 5 mm distance.
If the Antenna Connection is directly used for a radiating whip connection, keep at least a 5
cm radius free area. In case of coaxial cable connection 5 mm radius will suffice.
Reference Rules
The
RX-AM4SF
receiver is EEC certified and in particular it complies with the European set of
Rules EN 300 220-3 for class 2, and EN 300 683 for class 1. The equipment has been tested
according to rule EN 60950 and it can be utilized inside a special insulated housing that assures the
compliance with the above mentioned rule. The receiver must be supplied by a very low voltage
safety source protected against short circuits The use of the receiver module is foreseen inside
housings that assure the overcoming of the provision EN 61000-4-2 not directly applicable to the
module itself. In particular, it is at the user’ s care the insulation of the external antenna connection,
and of the antenna itself since the RF output of the receiver is not built to directly bear the
electrostatic charges foreseen by the a.m. provision.
