Dimensions

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 .

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

MICROWAVE POWER AMPLIFIERS FOR  RRL

BAND PASS FILTERS

It is intended for separation and selection of VHF,UHF and microwave  signals.
Used on the input or output systems of satellite, radio — relay  communication and TV engineering
Input /output of filters are coaxial ports  (SMA  Female).
Advantages:
— low  insertion loss;
— excellent  rejection.

Filters are produced in following modifications:

Type  Frequency range, MHz  Relative band pass(%) 
VHF TV-filters 50…250 2,5…13,0
Band pass filters BPF-2,2 470…800 0,8…1,5
UHF TV-filters 2000…2300 2,0
Band pass filters BPF-2,6 2500…2700 1,0
Band pass filters BPF-5,7 5700…5900 2,0
Band pass filters BPF-7,5 7100…8500 1,75…2,1

MICROSTRIP DIRECTIONAL COUPLERS

We are suggesting the directional coupler on multi connected lines with 3 dB transient attenuation (Lange bridge) in hybrid-integrated implementation (DIC).

Various modifications of these devices are released:

Modifications Frequency range,GHz
DC 1-2 1…2
DC 2-4 2…4
DC 4-8 4…8

All products modification can be delivered as printed-circuit board and as case with SMA-F connectors by customer request.
