The photo of the cable, any manufacturer can meet / know the cable is for reference, but we do not only have useful reference meters ..... 097m, 095m, etc. meters to see you spend or if you saves the length, cutting many meters.
For motorized antennas, apart from the loss, it is important that the living (center wire) 1'13milimetros either a minimum or you will have trouble moving the antenna, if it is 1'33mm better.
Cables ordered low (28dB / 100m) are almost all 1'13mm.
With 22metros not have problems, but always with custom motor cable or fat will have voltage drop and the motor will move wrong.
Taco metal (10mm ==> 12mm drill) / metal Taco (10mm ==> 12mm drill).
Taco cheap metal, use the corect bit, "never countersink" (10mm ==> 10mm drill).
Depending on the wall where you install the bracket, you can use metal studs (reinforced concrete walls) with 10mm diameter studs, you need to drill 12 diameter, not a bug, that's right.
For solid brick, you can not use metal wall studs break it, you have to be plastic.
The correct size for the screw (light).
Tacos quality Hilti or similar 10mm, 10mm drill.
The 4 grommet mount and balanced support, then put another 4 more.
Please washers for screws.
As a motorized antenna, remember to leave the bracket to level 2 of their faces.
Unmount the disk (4 screws) and place on a flat table, otherwise Apolla 100%, you will lose signal.
It pints of being 90cm, measured the height and width,, quick calculation.? the mean is the real measure, as is a helipse (S = pi.r1.r2)
In my case, 98x90cm = 94cm antenna average.
98cm = 49cm r1
90cm = 45cm r2
We 0'692 m2
94cm circular antenna = 0'693 m2. (S = pi.r2)
So you know you have/Asi sabes que tienes.
PD: It is good to have insurance antennas, many home insurance cover it, check.
