Hi. A customer has a rather thick wall at their site. Itsmaking mincemeat of the signal to their 7921 IP phone. Can I attatch different antennae's to the 800 series router? specifically something omni directional?
Solved! Go to Solution.

You probably want something other than omnidirectional, maybe a patch antenna so you can blast through the wall.
Yes, you can replace antennas. You should be able to unscrew the rubber duck antennas and connect a different one. Cisco uses an RP-TNC connectors for their antenna types.
Here's a listing of Cisco antennas. Make sure to get a 2.4GHz one.

ah great. I wasnt sure that they were all RPC-TNC connectors. All I need to do is sort out some extension cable for the antennae now! Thanks!

Hey Huw,
Just to jump in for a minute :) Cisco does offer "low-loss" extension cables for sale (like the two listed below);
AIR-CAB020LL-R
20-ft. low-loss cable with RP-TNC connectors
AIR-CAB050LL-R
50-ft. low-loss cable with RP-TNC connectors
Cisco Aironet Antennas and Accessories Reference Guide
Hope this helps!
Rob
PS: They also come in 100 and 150 foot lengths.

The 50 foot cable jobby appears to be £80! I think I may suggest 2 paper cups and a long piece of string...

Hey Huw,
Hahaha ....yeah, nothing in life is cheap ;-) I like Semiphore flags as well!
Cheers,
Rob
PS: These are just the Cisco versions of these cables. You can probably order them up from a local supplier at a somewhat cheaper co$t.
