Scene 1: A meeting room, a bunch of TV transmitter engineers are sitting round a table. With an accountant.

Engineer 1: 'If we use this form of broadcast antenna we'll have good strong signals all year round.'
Engineer 2: 'Which is what we want. Right?'
Accountant: 'Hmmm. Looks a bit pricey to me. How about this design, which is cheaper.'
Engineer 1: 'Yes, but with that one the signal will drop in the summer.'
Accountant: 'People should be outside rather than watching telly in the summer. Use the cheaper one'

Scene 2: Another meeting room, another bunch of engineers, this time they are the designers of TV input circuits. And of course there is an accountant there too.

Engineer 1: 'If we use this circuit the TV will work, even with low level signals.'
Engineer 2: 'Which is what we want. Right?'
Accountant: 'Yes, but if we take out that amplifier the TV will work for most people, save us some cash in components and we can also make a fortune selling aerial amplifiers.'

And this folks is why every summer televisions in our area stop working....
