Well after my thread last November I am finally about to install my outside aerial. (a few notes below).
But my question for tomorrow's task is... what are the best wall bolts to use? The T and K are 12" size and I will be putting them about 80 cms apart for a 3 meter pole. The wall is a very good quality dense brick circa 1950s (not the cheaper sort used nowadays!!!).
The specific reason I am asking is that when I bought the aerial pole from TLC I bought some all metal expanding type bolts from TLC that seemed to be the ones recommended, but seem pretty darned large!!! They are Rawlbolt M10 which need a 16mm dia hole drilling in the brick. http://www.tlc-direct.co.uk/Products/FXRBM10.html
Looking on the Satcure site he seems to talk about plastic wall plugs of the sort used by Sky for mini dishes, which would be a lot easier.
Just a few notes ... any comments welcome..... - Today I put a small log periodic aerial on the end of the pole and positioned it around in the general area I was proposing to put the aerial and was very pleased with the analog signal quality from Crystal Palace. We are in Maidenhead 30 miles away just about level with the bottom of the Thames valley and normally a bit of a tricky reception area. I then coupled up a DTV box and got an amazing maximum rating digital signal quality. I was very surprised, as we have a Triax Unix 52 aerial (14.5dB forward gain) in the loft (slate roof) with poor results, and I was proposing to use this outside because of its high gain. But after the good results with the log periodic I think I'll give that a try first! I'm not sure of the spec of the log periodic but its much lower gain than the Triax. Fortunately because of the positioning I will have a short aerial lead of about 3 meters before it goes into a distribution amp in the loft.
I used a log periodic for the signal checking exercise because it is much lighter than the Triax and easier to wave about to check for best position.
