Yeah, that is good value. I payed just under 60 squids for the 2 of them 6 months ago. The second book pulls all the info learned in the first book together, plenty of eureka moments in it . From my understanding, too many people were failing the ccna exam, so cisco split it into 2 exams, icnd1 and icnd2
For a thorough understanding of ip i would recommend the cisco icnd1 book, available from amazon, or to trully understand the way it all works, the icnd2 book as well. Both excellent books, that relate to the entire ip concept with pratical application to cisco products, but the theory in them relates to all ip products
Yep agree. but unless you get the pressure spot on it crushes the cable. staple guns only have 2 settings, and there is no way of judging the hardness of the particular spot you are driving one into, so even if they had multiple settings, still no good for a coax. when i say crushes, its only a minor change of the shape of the cable that is needed to affect it, so staple guns are a no-no in the coaxial world
Staple guns for 6 core etc = great
but for coax? a no-no imo. if you compress the coax you affect its transmission properties higher up the spectrum, making balancing of systems hard to impossible in some cases.ok, if its only 10 meters of cable, but above that, not worth the risk.
Im speaking from knowledge of large aerial systems, but the principal holds true in cctv cabling too.
