After looking at various options I decided on the rear nearside skylight window, installation was fairly painless although I would recommend getting somebody in my case the wife to help you align the 2 sticky pads, once they are on there's no really taking them off. Another thing to do is make sure the end of the counterpoise is pressed against the inside glass (it has a rubber cover) otherwise it vibrates against the glass. Modern technology really does develop in leaps and bounds. Imagine talking about mobile radios, broadcasts especially made for smart mobile phones and crazy mp3 gadgets twenty years ago. No one would have believed you!
