[QUOTE="chris2k2, post: 619899, member: 326863"] cheers for the replies.......would the following calculations be correct.? say a customer wants an aerial with 4 aerial points around the house... each aerial point requires 10 meters of cable..... so im going to use a decent aerial, mast head amp 10db gain with 4 outputs.... say at the aerial we have a masurement of 45dbuv signal strength after the mast head amp would we have 55dbuv on each output.? (as the gain is 10db) then say 3db loss on each cable run, and 2 db say for connectors.... thats a 5db loss in total. so........ 45dbuv + 10db(amp) - 5db (loss in cable/connectors) = 50dbuv at each outlet.? is this correct or am i looking at this wrong.? cheers chris.... ps ...dont want to look a numpty when i go out into the real world....lol [/QUOTE]
