<p>The key difference is the lack of RJ45 termination on the cable
coming down the tower. If you don't give the water somewhere to
go, it'll go right into the RJ45 fingers and with PoE on there,
it'll corrode and short/open in no time. The punchdown blocks let
it drip down without touching any copper. One can also remove the
jacket, and shield, and plastic film from the cable to let it drip
before an RJ45, but I found that to be cumbersome to do, ugly
looking and fragile.<br>

<p class="MsoNormal">In the case of Lookout, the incoming CAT
cables went into the bottom of the lightning protection
similar to your picture at Haystack. Once the jackets of the
CAT cables were compromised up above, the water rode down the
jackets clear inside the building. Ironically the lightning
protection wasn’t affected, as the excess cable looped inside
and upward entry into the lightning protection served to
stop/slow the path of the water. It was mostly when the
cables were unplugged and left to hang that the water started
dripping out. It could have been worse. The hardline that
broke free up above did a pretty serious number on the CAT
cables, stretching them and allowing them to abrade on the
angle iron / etc.<o:p></o:p></p>

<p>Water water everywhere! New water drainage devices have been
installed @ Haystack. May be useful elsewhere. Surprised to
hear SnoDEM was affected. Those cables are really well
supported.<span style="mso-ligatures:none"><o:p></o:p></span></p>

<p class="MsoNormal">The cause of the damage to both PTP link
CAT cables was due to another tenant’s antenna hardline had
become detached from it’s mountings and fell toward the
inside of the tower, stretching both CAT cables and damaging
them.<o:p></o:p></p>

<p class="MsoNormal">New CAT cables were pulled for both
Triangle and SnoDEM PTP dishes and the site is stable once
again and fed from both sources.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Sector 2 is still down, as we simply
could not get to it on this trip. S2 is substantially
higher on the tower and after the first two antennas were
corrected the call was made to stop there due to fatigue and
waning daylight. It is unlikely that S2 will be fixed
before winter, but it should be able to be done as soon as
an opening allows in the spring.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">While we didn’t go up to examine the
cable, it was leaking water through the jacket down at the
tower base just like the Triangle and SnoDEM PTP dishes
were, so it likely shares the same root cause. <o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Apologies we weren’t able to get S2 done,
but at least it looks to be cabling instead of a hardware
issue. For now S2 has been unplugged at the lightning
arrestor.<o:p></o:p></p>

<p class="MsoNormal">Thanks to Kenny Richards, Scott Honaker,
and Jim Irving for joining me to help make this all
happen. We were fortunate to luck into likely the last
weather opening for the season.<o:p></o:p></p>
