[QUOTE="Vipersan, post: 890281, member: 325666"] Not to worry Llew there are other manufacturers ... I am wondering though ...if the convention of standard H/V switching could be utilised .. 13v/18v .. The difference being 5v ... presumably it would be possible using a simple resistive ladder or op amp to produce the vcc needed only when 18v is present ? such that only switched on when 18v present ...and since it is such a low current needed..the supply could be generated in line by the lnb switched voltage ? so in theory it could be constructed inside a simple die cast box with only in/out F connections ....
