You are very welcome and you are also right , I am always right!! lol lol lol . Glad I could help.
"Flat coaxial cable" you said and I wonder , How can a Coaxial cable be flat because for it to be "coaxial" it has to "share" a COmmon AXIs therefore it must and have to be cilindrical in shape . But in very rare cases I could also be wrong for I am also a Human Being lol lol. I am just kidding but maybe you refer to the FLAT Cable adaptor that has 2 Female F-Type ends and is very usefull for running Coaxial cables under doors and windows because drilling a hole is a no go. If that is the case , please call it Flat Cable as appropiately Eagle Aspen , one of the manufacturers calls it. Too bad some distributors calls it Flat Coaxial Cable. I repeat I was just kidding.
BTW , Could you be more specific on the problem of the Flat piece? . Do you think it got mechanically damaged , Did it bend to the point of breaking? , Was it due to wear and tear (the door constantly hitting it? for instance). Do not get me wrong , it is a nice solution in some cases when drilling is not an option but as a Telecomm Eng (at least in Cuba I can claim that) I would rather prefer running a straight, un-cut , coaxial cable at all times. But I wonder specifically in these Satellite applications how much of the signal you loose by inserting these small pieces. Anything inserted to the coaxial line will always have some insertion loses. I have not found technical data on this matter yet. Does anyone knows?
