I purchased a UHF aerial kit that receives freeview HD. It is an outdoor aerial. Once I put it all together(some of it was already pre built) it looks different to the photo on the instruction booklet. I drew an arrow on the booklet to show what is different to that and the actual aerial

The aerial elements have been layed flat for easier packaging. You need to rotate each of them 90? where they attach to the boom. The plastic pieces should snap into place. (The aluminium fins will then be sitting in the vertical plane).

Does the aerial pick up the TV channels clearly?

Don't forget to mount the antenna in the correct polarity depending on what transmitter you are pointing it at. For horizontal polarity the short elements will be horizontal, for vertical polarity they will be vertical (i.e. pointing up and down).

Did what you said to the elements and it worked. Cheers
Any idea how I point exactly to the transmitter?. I know what my transmitter is and the polarity and the general direction to point it in
What percentage should I be looking at to get a good quality picture in heavy rain?

I used Google Earth to line up my antenna - basically locate the transmitter on Google Earth, and then draw a line between the transmitter to the point on your roof where the antenna is mounted. Look for a visible landmark in between the two points (i.e. along the line that you've drawn) - for me, it was the corner of a house across the park behind my house. Aim antenna at reference point.

never thought of Google earth. Where I live i am just over a km from the transmitter and can easily see it even without my glasses. But Google Earth, who would have thought eh.
