ROTO ANTENA is much cheaper than any other known device for receiving TV
signal from various directions.
ROTO ANTENA is intended for receiving VHF and UHF TV signals. The antenna is
equiped with a low noise amplifier produced in SMD technology. Antenna
amplification of 15 dB at VHF and 20-25 dB at UHF area provides quality
reception in urban areas with a strong field as well as in those areas
distant from the emitter.
ROTO ANTENA is the right choice for TV signals reception in valleys or
buildings lower than the surruonding area, where we often have to be
satisfied with the reception of the reflected but not direct signal.
ROTO ANTENA has the TV signal 330° maximum rotation which can hardly be
achieved by using other antenas rotatator which is in the safe and hase the
speed 4-5 rounds/min. Power supply of the antenna amplifier and rotator
motor is carried out by the coax cable. Antenna rotator is started by
pressing and stopped by realising remote control button. This motor has
built in limiter which changes antenna rotation direction after reaching the
above mentioned rotation maximum of cca: 330° or after coming to a phisical
obstracle. Easy operatting of antenna is achieved by the cable 10m long
which connects command button supplied from the rotator motor. First, we
select pre-memorised channel on TV set, than by pressing the push button we
rotate the antenna until the best reception is found. If we still have a
good reception after switching to another channel, there is no need to
rotate the antenna. When the antenna is rotating at a strong signal there is
a change both good and bit worse reception, while at weak signals there is
posibility of losing the reception. Then rotation of antena should not
stopped but continued until reaching the reception of wanted channel. This
been acheived by specially designed antenna parameters (beam widith,
front-back ratio).
ROTO ANTENA can be easilly installed on the pre-built antenna supporter with
the help of a double fixing bracket. The set includes 15m coax cable to
connect antenna amplifier with the supply source. |
