Extending cable on Antennae

Hi folks

Is there a way to extend the directional antennae on an AP60, for example a directional AP-ANT-4 9dBi unit? I want to direct the signals from both antennae down two aisles in a warehouse, but the cables are too short. I need a cable span of about 3 metres/yards.

I can't put a second AP in here because the cabling is cost prohibitive for the customer and there is no local power ro connect an additional switch.

The SMA connectors on the antennae appear to be the "wrong gender". Female connector with male part and male connector with female part.


I can't see on the website whether this is possible or even if Aruba do not recommend this.

Any help would be greatly appreciated.

Thanks in advance,

Extending antenna cable

There's no problem to insert an RF extension cable between AP and antennae. You'll need RP-SMA (reverse polarity) connectors on both sides, and it is recommended to use a good quality RF cable. Aruba does not provide this, but this can be sourced from multiple 3rd party vendors.
Make sure to adjust (reduce) the antenna gain as provisioned for this AP in AOS by the amount of loss (in dB) introduced by the cable.

Mark,

One thing to keep in mind is that the antennae work together to provide
diversity. If you point on antenna on direction and the other a
different direction, only one will be active at any given time, so you
won't cover both directions.

If you need two directional antennae pointing two different directions,
you must have two APs.

Having said that, you can order low loss (LMR-200 or LMR-400) coax and
have it terminated with the appropriate RP-SMA connectors (male on the
AP side and female on the antenna side).

Thanks guys

I'll get that sorted today

Another thing..

The 2.4GHz wave length is 4.92 inches. This being said the antenna should be placed no less than 5 inces apart and no greater than 20 inches apart to support antenna diversity correctly in the 2.4 GHz range.

Hope this helps,

Thanks guys

That worked out fine:)
