Even though I have installed at a guess over 100 satellite systems from simple zone 1 sky dishes through to 1.1m triax on usals motor and everything in between it's all been on an enthusiast basis. I'm now going to be putting up my own personal system comprising of a 1.2m Andrew dish, jeager 1224 El H to H motor with elevation actuator sitting on top of a 3m 76mm galvanised pole using 2 heavy duty K brackets. My only worry is should I use expansion bolts to fix the brackets to the wall or standard bolts/plugs? THE dish is going on a east facing wall and can be exposed to high winds now and again. Any advice from anybody who has had experience in similar set-ups would be appreciated, regards

Brass rawl bolts from most hardware outlets will do the job. I think they are what would be classed as expansion bolts.
I have a 1.5m dish on a Jaeger 1224 motor that is anchored to concrete kerb stones using brass rawl bolts. It aint budged in over a decade

This comes down to personal preference. I used to use metal expansion bolts.

But now I prefer 8mm x 70mm coach bolts (13mm spanner head) and 10mm plastic plugs.

It also depends on the material of the wall and thickness of it. Sometimes, to be completely sure the bolts will not come out of the wall, it is easier to drill holes through the wall and put INOX threaded bars via those holes. I used this method to attach not only one antenna to the wall but the whole platform where I can walk and work on my antennas.

The other option for wall fixing is to use chemical resin and threaded rods.
If using this method make sure all the dust from drilling is blown out of the holes so that the resin can form a good bond to the substrate.

The disadvantage of chemical resin and threaded rod studs is that you cant remove them afterwards like you can with expansion bolts.
You would need to cut off the protruding threaded stud and make good if the bracketry was no longer required
