Re: [WISPA] Tower standoff or not question

2009-08-03 Thread RickG
Perhaps a larger problem is having the copper cable run down the leg.
I had a tower with a 10' standoff and the ethernet ports were
routinely fried - with lightning protection. I put a switch on to take
the hits until getting fiber run up the leg whcih cured the issue. At
the same time, I moved the equipment off the stand off and onto the
leg but never had an issue. -RickG

 New commercial tower we will be setting up gear on, about 325ft up on a
 400ft tower.

From a lightning perspective does it matter whether you install on the
 tower legs themselves or on say 2-3ft standoffs?

 We were asked to reduce weight and just install on the legs (the gear can
 attach no problem).  I'd just like to know if there are any unforeseen
 electrical consequences.  Thanks.

A good reason to mount your antennas on standoffs is so guys like me don't have 
to climb around them.

RE: [WISPA] Tower standoff

2007-05-21 Thread Mac Dearman

  Well - - I guess I will respond on list then ;-)


It has been out experience in dealing with these big honking omnioid HPOL
antennas to pre-mount and tie everything down (jumpers, AP's, grounding
...etc) everything you can before pulling it up the tower. It will cause you
to pop a roid or hernia wrestling the HPOL omni onto a 4' standoff up the
tower not to mention just mounting the standoff by itself is a chore at
300.

  The real trick to making it easy to mount a pre-loaded 4' stand off up the
tower is how you tie the standoff on the ground. It will take several
carabineers' and at least two short pieces of web rope (rope) attached to
the hoist line. The upright attitude of the standoff and antenna should be
as it will be after install. In other words - when you start the accent of
the standoff - - it ought to go up the tower just like it will be mounted -
- with the omni poking straight up. This way the man on the tower is not
trying to hold it in place - the ground man holds the load while the tower
monkey attaches the standoff.  The other key thing is to have the pulley up
the tower at least 15' (if possible) above where the standoff is going to be
mounted as this makes it a lot easier for the guy up the tower to get the
standoff lined up on the leg of the tower. Bolt the top portion of the
standoff first and then let the weight off the rope and the bottom portion
of the standoff will fall against the tower leg ready for bolts.

 The biggest gotcha when pulling up pre-loaded standoffs (with fiberglass
Omni's)is that if you don't have the proper setup then your omni will go
into the tower as you are pulling it up and snap goes your new fiberglass
omni! We ALWAYS use a large carabiner attached to the eye that the load is
connected to and then run the pull end of the rope through that same
carabiner   - - this allows us back away from the tower and as we back out
away from the tower the gear we are pulling up also is pulled out away from
the tower. It gives the man on the ground complete control of the gear going
up. I have seen times where we would be close to 100' out from the base of a
tower - - - depending on the height of the tower and location on the tower.
This carabineer's sole and ONLY job is to attach the load to the pulling
rope - - do not hook any gear to this carabiner - it is just a loop for the
pulling end rope to go through.

It may take a pic to explain that! :-)

 I'd like to hear, either way, as well.
 
 I'm going to be putting up my third 4 foot standoff tomorrow,
 and would like to know if I can make this one easier :)

 Mac,
 
 This is not off-list, but I am interested in your stories.  We do small
 tower work ourselves and I always like to learn from others
 mistakes/lessons.  Is this stuff you can share on-list?  If not, send
 them off-list to me as well.

 Mark,
 
   We found that a minimum of 3' off the leg of tower will get you by,
 but we have gone to 4' as a general rule here.
 
   If you have never hung standoffs with big antennas on a tower before
 and would like to know some of the lessons we learned the hard to make
 things easier - ht me off list and will be glad to share with you.
 
 
 Mac

  I am setting up a new tower and I will mounting at 200ft on a 230ft
  tower, it is a triangular tower with an approximately 3ft face. I am
  starting with an omni and I am trying to determine how far off the
 tower
  a 2.4 HPol omni should be mounted to minimize tower interference.
