Hi Bigron,thx,for your reply!
in the meantime,i contact,some satelite dealers in germany,one replys me,and told i can use car window heaters, for the winter,that smells the snow and fit it on the backside of the antenna,but i dont know how i can controll,the intensive of the heat,in this winter,one,of the panel of my 2,40m mesh dish,has a little damage ,so know i am fear when next winter is coming,that other panels are infected,when snow is freetzing,8 month left to find a solution
maybe i dont find one,and i must buy new mesh dish every 5 year

we will see...
i try to fix problems,before it happens,but sometimes,iam to late.,.
problem, i cant install fullsize dishes on roof,coz they are to heavey,and,when it is windy,the mesh is better!,otherwise,maybe a fullsize dish,crashed into nabours ground!
the system,what i imagine,in my mind,should only swtich on ,and needs power,when it is 0 degrees outside,or a sensor detect freezing,maybe,there are also solutions avalible,to controll the heat intensive, dont find any information about it on the net.what system,was avalible,in the past?
