Wondering how to mount this type of TV antenna bracket
http://www.kjell.com/sortiment/ljud...tmateriel/fasten-stativ/vagg-nockfaste-p30941
on an asbestos-cement outer wall?
The antenna mast pipe is currently only attached at the roof edge, which however has started to give slightly under the load, and the idea is to complement with another mast pipe downwards, fastened with the aforementioned wall brackets to gain proper stability...
The house has 9.5 cm wall studs with single plasterboard on the inside and asfaboard as well as asbestos-cement panel on the outside.
Since the asbestos-cement panels are almost 50 years old and brittle (I know from previous experience with them), it feels unsatisfactory to just plug into the asbestos-cement (which is about 1 cm thick), or am I wrong there?
I have previously used 6D molly plugs to attach smaller things to the outer wall (like some externally routed electricity) and 8D molly plugs (do they exist?) might work... ? (I used the 6D molly plugs so that they gripped both the asfaboard and the asbestos-cement, so to speak...)
More ambitiously, one could remove some of the plaster wall on the inside and insert a couple of noggings and then put the plaster back with some filler, etc. (I have done similar things a few times, so I'm quite used to that - but it does take some time...) and then screw the antenna brackets into these noggings from the outside with something like 10 cm long lag screws... : is this unnecessarily overambitious perhaps?
Any other tips?
Best regards

OK - that was what I meant with my last option, although I formulated it a bit more long-windedly 
.
Do you place 45*70 vertically (on the edge) or horizontally by the way? I usually have them standing in similar situations (you can preserve the insulation by compressing it a bit, and it provides better "stability contribution" to the house to the extent that it's needed), but a neighbor of mine who considers himself knowledgeable if you are to judge by all the advice he gives me, says they should be horizontal ... .

Hello!
Why not place the antenna in the attic so you avoid all the problems of it being inaccessible on some mast pipe and looking ugly. TV antennas on the roof are from the days of past analog times and highly outdated, unless, of course, you live in a really difficult area.

Sure - I will answer that - the house has a FLAT ROOF !
Looks like a big shoebox !
The reception conditions are notoriously difficult actually - although it's
relatively close to civilization in Österlen - some have given up
and switched to satellite - I've managed quite well though ... .
In the long term, I intend to have 3 separate mast poles, each 6 meters, spaced two meters apart - one UHF for Karlshamn, one UHF for Bornholm, and one VHF for Hörby - if that doesn't suffice after amplification and various tricks, I'll try 9-meter ones (like galvanized 1 1/2 inch poles might be required for that ...).
But first I will assemble a 3-meter, 38 mm mast pole piece, purchased today, with the one that sits at the roof edge and see what I can achieve with just this single 6-meter pole ... .
