Anything less than 1.2m usually won't give you year round tv. A few places seem to be able to get away with a 1m dish but VERY few! I've had a 1.2m dish for 5 1/2 years and rarely have problems (only when there is very heavy rainfall). I've lost count of the number of small dishes I've changed over the years due to breakup in the evenings and winter. Now through to roughly feb/march are the worst months. Summertime is generally ok.

If you are in an area that suffers with lots of wind then make sure it's a good heavy duty support and quality dish - I've seen snapped brackets and dishes folded in half.
