A couple of years ago, having forgotten to pack our 'going away aerial' we were forced to buy another and were recommended, by the little electrical shop that we went to, to buy a 'Magic Circle'. These were apparently lauded by many people, especially long distance lorry drivers, as having a good performance. The aerial consists of a metal circle, about 6" in diameter, attached to a small box/stand which contains the signal amplifier and accompanying batteries to power it. The amplifier can be turned on & off by a switch on top of the box. The cost varies between about £9 & £15, depending on where you buy them.
In use we have found it to be almost as good as our old directional aerial. It works well for an indoor antennae and spends most of its time hanging from the ceiling by a garden tie or two (which also allows a good range of rotational adjustment). It might not be the perfect solution but it works well in most places for most of the time. When not in use it takes up hardly any space and has no nasty pointy bits to get damaged or indeed to cause damage. Would I get nother one? Yes!
