TV on acer 8930G

Hi
I have a tv card on my 8930g and it came with an antenna and a few other cables and a remote control.

I can scan and tune in channels when it is connected to the house tv aerial but obviously that needs to be connected to my tv..

WHen I use the antenna / aerial provided it does not find channels, has anyone else had this problem and if so, how was it resolved? It is just that the antenna is just too weak to find anything?

If it is too weak, have anyone purchased another indoor one and if so, which one?

I really wanted to use this feature but I cannot at the moment, unless i use the main house one which I use the normal tv for.

There was nothing in the manual about the tv tuner and maybe there is way to turn on the aerial? It is all connected and facing upwards, is it meant for outdoor use?

 

I think these are problematic at best unless you can plug them directly in to a wall socket.

 

I only really wanted to use it if we went away and there was no tv, or as a spare tv in the garden or something. Other than that got a tv in kitchen, living room and the 3 bedrooms, cant see me using it much really anyway and wouldnt replace any of the tvs with this (i.e take out of the wall). Has anyone bought an indoor aerial for their laptop though?
