TRANSMITTING TV ANTENNA

 

The two storied turnstile antenna is offered, each storey of which is formed  from two tubular batwing vibrators, fixed on common vertical mast.

Divider (one input and eight outputs) provides distribution of transmitting power to vibrators and reflections compensation.
For reduction of weight and wind resistance the vibrators of the antenna are made as a lattice.
Has mechanically strong and convenient in operation thunder-storm protective design.
On the customer's request is possible to produce the antenna on the decimeter range with the determined transmission frequency channels .

 

SPECIFICATIONS

Frequency range  400…960 MHz
Bandwidth  80 MHz
VSWR   1,35
Input   resistance  50/75 Ohm
Gain  6 dB
Nonuniformity of Gain  ±1,5 dB
Max. power  500 W
Dimensions  200x40x40 cm

VOLTAGE CONTROLLED OSCILLATORS (VCO)

 

Oscillators are used in radio devices with frequency tuning.
Have smooth frequency tuning  in a range.
The structure is sealed.


Six types of oscillators are produced: 

 

  • VCO-70; VCO-100; VCO-500; 
VCO-S-100; VCO-S-200; VCO-S-400

 

 

Frequency range:

VCO-70  65…75 MHz
VCO-100  88…108 MHz
VCO-500  430…520 MHz
VCO-S-100  30…110 MHz
VCO-S-200  30…110 MHz
VCO-S-400  220…400 MHz

The  VCO-S models contains internal synthesizer, by which the frequency with a step up to 5 kHz is set.
For synthesizer operation the external reference oscillator with frequency 1…20 MHz is  used.

Output signal level  200 mV
Harmonics suppression  20 dB
