RF cable for Cisco Omni Directional Antennas

[terminalvelocity777]

Hi,

We have some 1572's with AIR-ANT2547V APs and the customer has requested the AP body is hidden so are looking at remoting the dipoles on 1m to 3m RF cables so only the dipoles are visible, will the likes of AIR-CAB005LL-N or AIR-CAB010LL-N work we also have to do something similar for the Cisco 1532e's will those cables work on the antennas specified or do we need to get some bespoke cables made?

Thanks

Yes, those cables will work. What is important is the end connectors are correct, and those part numbers are.

George is correct here.  The other thing to keep in mind is if you plan on extending the cable, is that you mount the antennas properly and do not separate them too far apart.  You can always use another dual band antenna with a single housing and either replace the antenna end with an N-Type or get an adapter to go from RP-TNC to N-Type.  You will have some db loss, but your cable length isn't that bad.  It's really up to you as you have a varity of options to go with.  Most of the dual bands single housing may have 4 antenna leads, but you only have to used two and you can seal up the other two connectors.

George, Scott,

Many thanks for the fast and informative replies, we are going to try and mount the antennas the same width apart they would be on the AP just to keep everything within that scope.

I have rated your answers.

Mick,

Keep in mind that if the antennas are outdoor that you mount then properly with the connectors toward the bottom. There is a drip hole to allow moisture to escape. Also a drip loop is required to prevent water from traveling into the connector. Coax seal should also be used and lightning arrestor's if you want to play it safe. At least from the antenna to the AP or AP to the switch. Sometimes having both is better especially if the area has a lot of lightning strikes.

Scott,

Excellent advice and you have confirmed what I had planned on the install about the water ingress and 'drip loop' etc always nice when someone confirms what you had planned makes you feel you wasn't going too far.

The lightning arrest is very helpful is there a Cisco kit for this?

I have tried locating some photos for the install team of Cisco Dipoles mounted away from the AP body on RF cables but haven't been able to find any so will probably have to make a mock-up.

Once again thanks for taking the time to reply and share your experience.

Well you have two choices. There are N-Type inline arrestor's and then you can use a PoE rated Ethernet lightning arrestor's like this one:

i would put this somewhere not close to your equipment.
