During installation go step by step according to the next parts. 

 

4.1. 

Grounding 

The amplifier has to be grounded properly! Connect the screw on the rear panel of the 
amplifier  to your local grounding system with a copper cable; use a cross-section  of    

4 mm

2

 (AWG 12 ) at least

.  

 
Connect your transceiver to the same grounding system of your shack carefully! Use minimum length 
cables  and  make  certain  that  the  connections  are  both  physically  and  electrically  sound.  With  poor 
grounding, you may risk damaging your equipment, having problems with TVI/BCI or your transmitted 
signal may be distorted. 
 
 

4.2.  Coaxial Cable 

The output of the transceiver is to be connected to the input of the amplifier via RG58 or similar cable. 
For  the  connection  between  the  power  amplifier  and  the  antenna,    RG213  or  similar  coaxial  cable 
suited  for  high  power  is  recommended.  At  the  INPUT  and  OUTPUT  SO-239  sockets  with  Teflon 
insulation are used.
