| Instalacja antenowa na dachu 3 i 6c rotor RAK zasilanie i inne pytania |
| Hi Tom! Here description solution in my case. I have distance between shack and antena abt 30m. Near antenna mast I instal PS 230/13V- abt 15A and connect 6 and 3cm with DC.For 230V AC 3x0,75mm2 30m long; for DC 2x4mm2 2x 2m long. Rotation ( asimuth KR400 and elevation Actuator ) abt 30m multi lead cable (original for phone instalation) with wire 0,25mm2. For elevation indication one mechanical connected potentiometer( abt 1k ) is used. Lines for indication have only one wire 0,25mm2, but in lines for motor( in KR400 and actuator ) is 2 wire in paralel conected. For IF RF is RG213 used.. for output RF is used FSJI50 1/4" coax. Isolation problem - influence 6cm TX in 3cm RX ( and ereverse) is solved, that in same time BOTH transverter is on TX... or BOTX on RX !!! GL+73 ! Zlatko |
