As you add antenna and cabling you lose signal. Sometimes that's an
acceptable risk. If your existing locations are providing 'more than
enough' coverage then adding various antennae would probably work. Just
make sure you use very good quality cabling and keep it as absolutely short
There are ceiling antennae: http://www.hyperlinktech.com/item.aspx?id=2011
That one is listed as using an N-female connector. I believe it's an
RP-SMA connector on that AP. So an RP-SMA to N-male pigtail should be
There are also on-wall units: http://www.hyperlinktech.com/item.aspx?id=2115
Look at the technical datasheet PDF when picking antennae. Those polar
chart (round) diagrams will give you a good idea about how the antenna
covers a given area. That's important when it comes to mounting them.
Make sure the antenna is aimed properly to best match it's pattern with the
area in question. What sort of antenna to use will depend on the area you
need to cover. As in, an open room might be great for a centrally
positioned ceiling antenna. But that sort of antenna might be useless for a
long straight hallway sort of area. For that a wall-mounted sector antenna
might be a better choice.
Make sure to use ONLY as much cable length as the situations actually
requires. As in, if you only need a 2ft length then don't get a 10ft one
and coil it up. You're just losing signal strength over the longer cabling.
Buy the right lengths necessary. And avoid using connector adapters, get
the cabling with the correct ends on them from the start. Note there are
right-angled N connectors so a ceiling antenna's cable can exit without
being bent into too tight a curve. When using coax you really want to avoid
bending the wire. There's a minimum bend radius all cabling of this type
requires. If the lay of the cable needs a different exit angle then get the
correct end to the cable instead of bending the coax. The more cable,
connectors, and adapters you use the more signal you lose.
If you've never made cables of this type, save yourself that hassle and just
order them ready-made. Dealing with tiny SMA and N type coax connections is
less than trivial. If you're doing it all the time that's one thing. But
for a DIY situation you're just asking for yet another source of signal loss
and debugging hassles along the way.
