Who told you that?
I have seen horizontal omni's and knwo how to build them
I have mounted Yagi's vertically (I know how to build them too)
I use a high gain Wi-Fi device basically it is a Linksys WGA-54g (Wireless game adapter) which comes with an Omni antenna the kind that sticks up like a finger.
I built a device to make it highly directional.. Looking at the unit's signal strength meter a very weak signal (NO adapter) around a six Is closer to 26 with the adapter..
How to make adapter..

George re-cut the antenna on his Linksys.. I did not.
I did nominate George for an awared.. he won too.
To take this a step further, technically speaking most modern Enterprise Wireless Access Points are dual polarized, so polarization of an antenna pointing at it becomes less of a concern. Also most antennas inside cell phones, tablets and laptops are also dual polarized these days. Polarization is less of an issue for the average end user using modern hardware. It is really more of an issue for geeks like us trying to make complex solutions or people using really old or really cheap hardware.
