What are yours?

Mine is just the humble indoor aerial, it's just one of the most irritating devices ever & is possibly one of the only devices in the world that only seems to bloody work properly whilst your adjusting it. I mean even with an amplifier they are still pretty much useless unless you're in some signal hot spot, but the one thing I hate most about them is as soon as you sit down the signal goes, goes completely from the 5 bar signal strength you achieved all but a minute ago. This problem has only been amplified since the introduction of freeview where a below par picture on analogue becomes an irritating jerk fest on freeview. Indoor aerials!!! FUCK EM!
