I have one that cost double that and hooked up to fixed house aerial is flawless. Never tried on a portable.

I had a similar one (probably the same but made of a different coloured plastic in China) which I found did the job on a laptop OK but the little telescopic area was a bit naff in areas of a poor signal, and ariel connection to it was prone to fall out.
