Hi Nick,
I liked the thought of the Korner 9.2 - but for what I wanted to do I decided on the self build 5ele Yagi. Guying is likely to be expensive but definitely needs to be done professionally - and of course you'll need to get formal planning permission due to the height and prominence of the proposal. I've just checked and Havant County Council have a decent page on their web site (unlike my local council) explaining their approach.
I keep thinking about a 'proper' un-guyed tilt over support to give me an overall height of say 26ft - 20ft away from the house. But I it requires a 3ft x 3ft x 3ft concrete filled hole in which to bury or bolt on the base - so an expensive option. Current support is 18.5ft high and tilt-over - the new 5 ele is the biggest I dare put on it - but will be dropping it horizontal when winds above 50mph are prdicted - as I did this past winter.
