Microwave Band Issues
For most microwave systems, a completely non-directional isotropic antenna (one which radiates equally and perfectly well in every direction – a physical impossibility) is used as a reference antenna, and then one speaks of EIRP (effective isotropic radiated power) rather than ERP. This includes satellite transponders, radar, and other systems which use microwave dishes and reflectors rather than dipole-style antennas.

Famous quotes containing the words microwave, band and/or issues:
“The New Age? It’s just the old age stuck in a microwave oven for fifteen seconds.”
—James Randi (b. 1928)
“What passes for identity in America is a series of myths about one’s heroic ancestors. It’s astounding to me, for example, that so many people really seem to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldn’t stay there any longer and had to go someplace else to make it. They were hungry, they were poor, they were convicts.”
—James Baldwin (1924–1987)
“How to attain sufficient clarity of thought to meet the terrifying issues now facing us, before it is too late, is ... important. Of one thing I feel reasonably sure: we can’t stop to discuss whether the table has or hasn’t legs when the house is burning down over our heads. Nor do the classics per se seem to furnish the kind of education which fits people to cope with a fast-changing civilization.”
—Mary Barnett Gilson (1877–?)
