Neil,
You will find that there are directions that have less/more noise at a given
time of day... That does not mean there is a fault in the antenna...
At my qth in Michigan there are significant differences... In the evening
beaming NE to Europe - over top of the NE USA and Canada - is very noisy
compared to SW which is quiet, as long as the thunderstorms are not kicking
up... SE is just a roar from looking over the heavily populated states and into
the continuous thunderstorm Carribean... That changes in the morning when there
is more noise shooting into the night than into the daylight side of the
globe....
Even to the West half of the globe the directions differ... SW is the quietest
because I am pointing into the empty Pacific Ocean across the more sparsly
populated SW parts of the USA (compared to the east coast)... NW is louder
because I am pointed over the noise generating populations of the Midwest,
Central, NW USA, and Canada, and Alaska, and looking at polar region auroras,
and then into heavily populated Asia..
Anywhere there are people there is more noise... The USA is a long ways from
anywhere which makes the differences more noticeable to me...For you,
sorrounded by heavily populated land masses all directions may be more noisy
than I experience, but there will still be differences including which
terminator you are pointing towards at a given time of day...
