What to do in case of poor-quality reception of a radio or TV signal

Should problems with the quality of reception arise or continue, the Czech Telecommunication Office recommends proceeding as follows:

Czech Telecommunication Office recommends proceeding as follows:

1. The listener (viewer) must always first check his own receiving set.

a. In the case of reception through an individual aerial:

• check the installation of the receiving equipment, in particular the outdoor aerial (its suitability for the channel received, its mechanical condition, fixing, direction and polarisation), amplifier (necessity and suitability of its use), aerial lead (integrity, correct connection, the use of balun) and actual set (faultless functioning and proper tuning to the received frequency);

• it is generally impossible to ensure quality reception using an indoor (room) or other substitute aerial;

• in the case of doubt, it is a good idea to ask neighbours in the area about the quality of reception.

b. In the case of reception through a common distribution system, i.e. television cable distribution or common aerial):

• check the integrity of the subscriber’s lead, including its proper connection, and the actual set (its faultless functioning and correct tuning to the received frequency);

• in the case of doubt, it is a good idea to ask neighbours about the quality of reception.

• if no fault is found to your own set in your apartment, contact the operator of the common distribution system, who will ensure that any faults to the common distribution system are eliminated.

If a set-top box or digital receiver does not function as normal within a short space of time, we recommend restarting it by taking out the power lead for a few minutes or re-tuning the received channels in the way described in the instructions of the manufacturer.

3. Should problems continue with the reduced quality of reception and the faultless functioning of the receiver set of the listener (viewer) and the common distribution system, you may ask the Czech Telecommunication Office to identify the source of interference according to Section 100(6) of Act No. 127/2005 Coll., on electronic communications and amending certain related acts (Act on Electronic Communications). In the case of doubt, CTU may seek the confirmation of a professional company as to the faultless nature of receiving equipment.

4. No help is available should problems arise in connection with extraordinary conditions in the transmission of radio waves (always lasting for a limited period), apart from re-tuning to receive a different channel, if this is possible.

The locally-competent departments of CTU, whose addresses and contact details you will find in the Directory, receive and handle reports of disrupted reception of television and radio according to point 3.
