Pozdravljen Luka,
Še ene par linkov:
http://lea.hamradio.si/~s50c/hardware/coax.txt
http://www.wireless-lan-antenne.wimo.de ... asheet.pdf
http://www.interprojekt.pl/katalog/kable-RF/H155pe.pdf
Če boš kabel obremenjeval z RTTY, FM ali podobnimi načini dela, vzemi faktor rezerve vsaj x2.

Luka kaj si sploh prebral navodila od tega linearja?? 
LINEAR AMP Ranger 811
Each band has its own tuned I/P and the O/P Pi network has a nine-position bandswitch for better tuning. To aid tuning even further there are 6:1 reduction drives on the tune and load capacitors. These capacitors are a double module exclusive to Linear Amp UK Ltd.
The valves are cooled by a 120mm, low noise Papst fan which gives excellent cooling but is so quiet you will hardly know it is running.
Front panel features include two back-lit, flush-mounted meters which show plate current and grid current. The grid current meter also doubles as a relative RF power O/P meter, selectable on the front panel. Fully adjustable ALC is also controlled from the front panel.
Output power: 800W CW or SSB, 400W RTTY
Gain: 10dB nominal
Power requirements: 230V AC at 8 Amps, 50/60 Hz
Frequency coverage: All amateur bands 1.8 - 29.7 MHz
Valves: 4 x 811A, vertically mounted
Cooling: Papst 120mm axial fan
DC voltage: 1700V DC
Protection: Primary AC fuses, soft-start
ALC: Front panel adjustable control
Dimensions: 14in wide x 9.5in high x 16in deep 355mm x 240mm x 405mm
Weight: 23kg

Profesore, zdaj ko si ratal Sadni, lahko sse S50C navajas kot tech reference
Jaz se lahko posipam s pepelom, ce je glih S53MV ukazal na napako pri vecjem stevilu mojih sivih celic.
