looking to build one of the above, it will be out of 8mm ally rod and ally mast and beam spreader, plastic chock blocks to insulate and will be set at best swr around the dredded T5, got the 11m challenge coming up so thought ill get making a beam, it will be a heath robinson rotator, (rope and pully) and a print out of the azimuth map (so in my opinion) point and hope lol..... unless i can find a rotator cheep that needs a bit of work.
Will be 25 foot up on top of bungalow roof and only fields front and two sides another bungalow on the last side ( North )
any ideas would be good.

I have a 3 ele Sirio Yagi that is currently in my garage unloved as i chose to give my shack over to my grand daughter as a rather large Wendy house and currently am mobile only but there are plans to convert my garage into a shack. I won't be putting the Yagi back up as i prefer my Vector 4000 7/8w vertical. The Sirio yagi is pretty poorly built and I had to strengthen every element by inserting wooden dowels into them which strengthened it considerably helping it survive 70 mph gusts.I used a Armstrong rotator as i have no way of powering a rotator but i did a few back to back tests and there was little difference on tx signals on DX but rejection was of course very good using the Yagi.
I'd suggest a 4 ele if you have the room...good luck with the project
