Hi , this is going to sound daft but..

I need to keep the heat in (it's cold outside)

I need to keep the window open.

there is a small 30cm satellite dish on the window sill I need for sky
digital (the tv reception here is appalling - dreadful - you can barely
make out the shapes on the screen)

This dish is realy really small - unbelievable

With the window open , how can I keep the heat out.

Throw tissues at it
