AP-518 + AP-ANT-313 and extension cable.

    Hello everyone.

    I`m interested in AP-518 + AP-ANT-313 but I would like to install the antenna about 10 mts away from the AP. I`m not able to find in Aruba website the correct RF cable. Neither if it is possible to extend this distance the antenna from the AP.

    Does anyone has info about possible attenuation in RF cable and if I could use a generic RF cable?

    Thanks.

    I think using LMR-195 cable you could lose about 30 dB/100 ft, so for 10 meters it will be about 10dB or so.  You can go with LMR-400 or better to reduce the cable loss.

    Also add 0.5dB loss per connector

    There are many online  tools available to calculate cable losses. Here is one of them

    I would avoid antenna cables in general and long antenna cables as much as possible. The coax antenna cables are quite fragile, and you would even need 6 of them with the AP-ANT-313. Especially for the receiving by the AP, attenuation you can't really compensate for. Mounting cost may go up as well. Using an AP-575 may be a better solution, but you didn't share the deployment scenario and why you got to the AP-518+ (6 times) ANT-313.

    Hi Herman, thanks for you post.

    the scenario where we are working is an historical protected monument, and visual impact is critical. It is totally forbiden modify original structure, walls, etc due to his historical and cultural value. So AP-575 is not an option.

    The plan is placing the AP-518 in a IP68 box underground and 4 AP-ANT-313 in the streetlights hidden by a thin box in the same colour and shape of the streetlight (even the streetlight is made according to historic strcuture). It is assumable the the loss of signal quality to protect the place.

    In that case, have a look at the AP-565, which is much smaller. Even smaller than the 6x ANT-313, which may be challenging to get enough spacial separation.

    I can't find photos at the moment, but know there have been projects to hide access points in historic environments outdoor with an add-on that blended with the design of a lamp post. Also have seen APs hidden in 'mushrooms' or 'rocks' on the floor, similar to music speakers in some amusement parks, which is far from ideal for coverage.

    You may reach out to your local Aruba team and see if they know a partner that has done such projects in the past. It's probably better than reinventing the wheel.
