Do I need a Zone 1 or Zone 2 satellite dish?

Zone 1 satellites are smaller and do not need as much surface area to pick up signals and cover most of England. Scotland, Ireland and the north of England is classified as Zone 2 and so require satellite dishes with a greater surface area.

The goal with zone 2 training is to exercise at a pace that allows you to sustain your heart rate just below the aerobic threshold for a prolonged time period (typically 30 minutes+). This would be at heart rate of around 60-70% of your maximum (we’ll look at how to accurately calculate your personal Z2 below).

How do you classify hazardous areas?
