even if you have an existing cable lay out for your home does not guarantee that it can be used for Cignal or any DTH.
they should be able to check, if they determined that it is not within the standard of coax cable then it will not be used and will need to use a new one.
marami rin cases, na maganda ang bahay... yung contractor nilagay na cabling ay "Swan" brand... fake pa. kaya ayun, gamit ng bagong coax cable.
@naphster: Cignal can only be used up to the country where SES7 satellite foot print is available. like... HK, and part of China. Other than those country, sorry but you will not be able to use it.
