I have recently purchased a laptop with WMCE built in. The tv tuner works great when I plus the aerial in from home (that is on my roof). I have just been camping to the Isle of wight with it and was hoping to watch some tv. I purchased a portable aerial with a booster up to 20dcb from Maplin but when it searches for a signal it keeps saying nothing is found. The guy on site says the signal is excellent and we should have no problems. Is it worth me trying a better aerial?
