Is necessary an external antenna?

[nakedsnake]

I use HSDPA.
I have 3 bars of 5 without and it works well.
I need an external antenna? I will notice an improvement of the stabilty?
Does getting more bars improve speed?
Or the antenna increases the stability without gettings more bars?

Thanks
Best regards

An antenna will always improve reception and this could lead to better stability or even better throughput.

An antenna will always improve reception and this could lead to better stability or even better throughput.

Except maybe if the antenna's cabling is too long and substantially increases the SNR such that it is worse than without the antenna cable plugged in? which of course does not invalidate the fact that an antenna's purpose is to improve signal .

Wise a$$

An antenna, correctly designed, will increase the signal, but you're right of course. No use losing the gains somewhere else with bad cabling or connectors.

Always keep the antenna lead as short as possible and don't put any connectors in-line, i.e. don't use extensions.
