NodeAFH [8]'s guide to putting up a mast on a tiled roof, so that you
can get a better LOS for wireless (this is due to the fact that
thetron doesn't have a idea)
MOUNTING A MAST ON THE PEAK OF YOUR ROOF GALV/TILE
Please note local laws may vary but odds are its 3 meters from the
peak of
your roof or 10 meters from the ground, which ever is higher
FIRST WE NEED THE FOLLOWING EQUIPMENT
* a mast
* a peak roof plate
* up to 30/60 meters of guy rope (or washing line wire)
* a/2" locking ring
* a/2" guy plate
* 4 'O' end big ass screws
* 2-4 people
* 4/8 eye hook's
First get the plate in position and put the locking ring on with the
guy
plate on the top end. If its a 3 meter mast you want the locking ring
2
meters up the pole, from 3-5 meter masts you want it at the 3 meter
point,
at 6 meters you want it at the 3 and at the 5.5 meter points.
example 1
MOUNTING ANCHOR POINTS ON A ROOF OR THRU A TILE
Ok, now we work out where on the roof it will be and find 4 points
suitable for you to drill to install the 'O' end big ass screws.
Drilling through tiles is doable, but you'll need to increase the
number of spare tiles you'll need
If you do drill the tiles then make sure there is solid support
directly under the hole you're drilling, if you don't have this
support then Murphy's law says the tile will crack.
Rather than drilling through the tiles the eyebolts can be screwed in
at an angle, into the last baton. This baton holds the last tile up
and has the gutter attached to it. You'll still need the tube of
silicon but the tile survival rate improves somewhat.
There is another alternative to the above. It is also possible to buy
a mast that can be bolted to the house frame and a specifically
designed tile replacement to pass the mast through the roof. Speak to
a local antenna reseller/installer. These should cost between $70 -
$100 for the entire kit. The tile replacement piece can be sealed
water tight.
HOW TO DO GUY ROPES/WIRES
After installing them you want to cut guy rope thats a bit longer
than you need for each run, 4X7 meter runs will be fine for the lower
set of guy ropes the upper ones you will probably want 4X9 meter ones.
Now twist the ends through the holes on the guy plates.
If doing a longer pole you might want to just do the lower one first
and get it all working then do the upper ones by repeating the steps.
MANUAL MAST RAISING
Get a person to hold the pole where you want it to to be and get the
rest of the people to grab a wire and goto the 'O' end big ass screws
you already have installed.
Put the guy wire thru the eye hooks 'O' end while its hook end is on
the 'O' big ass screw make sure its loose enough that you can unhook
it but after you tighten it up that the guy rope is so tense that the
mast doesnt move.
Do all 4 then repeat the step and BAM to take down untension them and
you can lower and then add an antenna
