Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

Any Technical information about using a Nanostation M5 with a 2.4ghz omni antenna.

What kind of results can i expect?

I have no idea what s the consequence of note using a 5Ghz antenna with a 5Ghz Radio..

I work for A touring Show (cirque du soleil),I'm trying to create a wireless network within 10 Movableoffices/trailers. I would like to eliminate cabling since we are moving the trailers every 2 months to different states. I would like to setup the antenna once on each trailer. The thing is these trailers will be on the road after all so I need something ''aerodynamic".

I found this : www.luxulwireless.com/product...spherical-omni

But they are for 2.4Ghz...

I would prefer a 5Ghz network.

I'm covering 10000 square feet.

Thanks!

Re: Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

Do not use a 2.5Ghz antenna on
a 5Ghz radio. It will work very poorly
and may also damage the radio over time.

The Luxul antenna you show is actually
meant for 2.4Ghz indoor use, and they
don't have a 5Ghz version.

Here's an example of an inexpensive
outdoor 5Ghz 'stick' omni antenna:
www.streakwave.com/Itemdesc.asp?ic=OD5WM%2D6&eq=&Tp=
If the trailers are all in sight of the
sending radio, these will work fine,
and they don't have much wind load.
You could find even smaller antennas,
and could use magnetic base mounts
if the trailers have steel roofs.

Or, if a trailer has a window that is
visible from the sending radio, you could
put a NS in the window and use a suction-
cup mount (available as a Ubiquiti part).
That way, your installation is instant,
and there's no outside cabling/drilling.

Epcot: absolutely magical!) Dave

Which one?

thanks for the advice.

I did a little more research for the antenna and I found this :
www.mobilemark.com/shop/item.asp?itemid=954&catid=646

They are not as pretty but they seems more adequate for what i'm looking for.

Now I m at the point of which UBNT 5Ghz device I should pair with...

I was thinking of the new NanoStation M5, Because of the 802.11n capability but it seems that the PicoStation have more power to offer : 1000mw...

At the moment I own 2 nanostation 2 and i'm familiarized with the AirOs, As far as I know the best way to set these up is as Accesspoint WDS. I heard that the OS of PicoStation is slightly different and allow easier ''mesh network''.

Re: Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

I'm a bit confused about your layout.
You mention 10000 sq.ft, but I assume
you have a cluster of trailers where
none is more than 300ft from your AP.

If so you need very little power.

And you plan to use external antennas.
So the Nanostation's internal antenna
won't do you any good. Why not simply
use Bullets connected directly to your
outside antenna? That will permit you
to run CAT5 instead of coax.

I assume you are simply distributing a
bit of Internet. So you may not need
the 'n' equipment and its higher speeds.
But the price difference is very small.

I don't know of any setup differences
between devices, except for the radio
options such as antennas. Dave

Mostly the trailers are grouped in pairs and spread over the site within the 10000sqFeet and they are note located at the same spot each site/city we visit. So what i'm looking to achieve is a effortless solution for the connection at the setup, during the city in case a trailer needs to move and at the ''tear down''

I should have put it differently. Are
the trailer antennas in sight of your
AP antenna? If so, extra power may
have little effect.

If there's a metal building or a thick
grove of trees in the way, all the
power you can buy won't help. Dave

Only canvas tents can be obstructing.


I did a gig that was using canvas 2 sloped roof canvas / aluminium structure tents with absolutely NO effects.

That is quite the fancy tent!

Canvas will be transparent to your
signal; there may be minor reduction
from the steel suspension cables.

If your antennas are all in sight of
each other and only a few hundred
feet apart, power should not be an
issue. I would put the AP antenna
on a tall pole if possible; that's easy.

Consider mounting a NanoStation Loco
with built-in antenna for trailer windows
with a view to your AP antenna. Outside,
you could use the tiny PicoStation with
very high power and included omni
antenna; that would save an antenna
purchase and avoid coax cables. Dave

I'd put 2 bullets & 2 antennas on the top of the tent. One would be a link from the internet source, the
other would be the AP, they'd be connected with a short cable, and 24V wire running down to a power source.

Parkland, the tent wasn't the question.
Please read the whole thread first. Dave

Re: Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

I know the tent wasnt the question, just thought it might be a better AP than a trailer, just in case the setup requires an uneven ground level rig up.
If the AP trailer was ever "beneath" another trailer, there could be serious issues with getting the signals through a metal trailer. Were talking about antennas that are mounted 16" or so inches above the roof, so even on slightly uneven ground, theres a good chance the AP could be hidden behind another trailer. Even some random semi truck pulling through could potentially block the signal.
Maybe the trailer with the AP could have a 20-30 ft fiberglass pop-up tripod or something?
I dont know exactly what would work for your particular situation, but if it was me, I'd get the AP up above the average height of the trailers, and more if theres ever any chances of rigging up on uneven sites.
just my .02$

Re: Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

Sure--put the AP up high; that's why
I suggest putting its antenna on a pole.
You could put it on a big tent of course.

But you talked about something with two
radios on the tent--one for the Internet,
the other for the AP. What's that about?

If you're trying to describe some kind of
repeater, this is not the question either. Dave

Re: Using a 2.4Ghz Antenna with a 5Ghz Radio-->Good or bad?

I was thinking that if the trailer couldnt have an elevated antenna, the tent could have a link from the trailer with the internet source, and then a 2nd antenna acting as an AP for everyone else. Of course you could run ethernet up the tent to the top, I just though it would be better to avoid that using 2 radios & antennas.
Ideally, it would be simpler and easier to elevate the AP right from the trailer, if this is possible.
Yes, I was describing a repeater more or less. This would be a good option if they want to keep all the antennas low profile on all the trailers.
