Why am I not so elevated?

I'm in County Down, N. Ireland and the angle of elevation to hotbird or astra 1 should be around 20 degrees but I seem to only get a strong signal with an angle of a few degrees. Is my monobloc LNB causing the difference?

Why do you say that, are you basing it on the way your dish face is elevated?

An offset dish always appears to be looking lower than it actually is, the signal is reflected from the dish to the LNB which is not in the prime focus position, but lower down.

You should really make a FAQ for newbies on this site with all these questions.

Yes, been thinking of that for a while, but like all of these things it is a get around to. :)

I was basing it on the angle of the back plate to the vertical.

Well all I can say is that if you are receiving the satellite, then the dish must be correctly orientated, some brackets can be fitted the wrong way up, or have scales on both sides, from much of Ireland, 19E would be in the mid 20s.
