Cisco Indoor/Outdoor Antennas

Hi All,

Kindly excuse my ignorance. Please explain to me or point me to documentations that explain the effect of using an indoor antenna such as Ceiling mount omni-directional in an outdoor environment. Are there environmental implications such as rain?

Thanks.

I have some urls on this , may help you

Antennas - General

Antennas ship with basic hardware to mount antennas (such as U-bolts), but not the mast itself.

Basic mounting hardware is included with all antennas (except patch, whi

ch mount directly to wall).

Keep bridge antenna cables as short as possible (significant effect on r

ange/transmission rate).

If possible, use fiber and transceivers to connect Bridge to LAN (lightning doesnot travel over fiber).

Cables are not plenum-rated.

Use the calculator tool for bridge antennas/cables.

Antenna needs to be polarized in the same manner for proper operations ,

There are

Two planes of RF , E plane and H plane and they are 90 degree from each other .

Horizontal polarization is best for transmissions over water, since vert

ical polarizations exhibit a 180 degree phase shift and result in multipath pro

blems at the far end of the circuit.
