External Antenna for RT-N66U

[Raptor]

My opinion you have 5GHz now only because did other position of antennas.
Stock antennas has also 5dbi.

Hi ArCan. The stock RT-N66U antennas are 2dBi in both 2.4G and 5G. Its in Asus FCC documents.

Oh! Sorry my mistake. I didn't know it.
I always think that 5 because somewhere read about it.
Thank you very much for correction.

 

[WilliamY]

But stock antennas has same 5 dbi I think... why are you going to find big difference?
I have bought three http://www.ebay.com/itm/New-Dual-Band-2-4-5-8Ghz-9dBi-RP-SMA-High-Gain-Antenna-/130729553117
(now it's no longer available) waitting for delivery in couple of days.
I hope antennas will works in two bands with good SWR.
But I'm sure that I will need to expirimentaly find right channel with the best lever of signal
Unfortunately I don't have equipment for so high frquency to mesure resonance and SWR...

2.4 and 5.8 (!) it's mean last channels in 5GHz band...

Hi, ArCan

Please let us know how this antenna performs.

Thanks

I ordered those 9db antenna as well. They will arrive this week.

You may or may not be aware of this, but as you increase the gain of an antenna, the signal will actually go down in some areas while increasing in others. This may be what you're looking for, but you will not get a signal increase everywhere, only where the directionality is. On the other hand, the signal will decrease elsewhere.

Just install my 9db antenna and inssider shows the signal went up 3db

Correct me if I'm wrong, to these antenna, Is it the more closer the antenna, the less signal you get? so for a house around 2000-3000 sq ft., 5Dbi should be enough?

I would think it will give it better range. Anyways, these antenna are pretty long, a little over a foot long.

 

[AnthonyArmato]

I would think it will give it better range.

Either that or allow for Alien communication.

Sorry, you can change the shape of your router's radiation pattern to give you more power in particular directions (makes it less omnidirectional), but you can't put more total energy into radiation without raising the power radiated. That's physics.

On the other hand, you may only care about the directions where the radiation is increased, that would be ideal.

What I understand is that these antenna is not good to those houses that having 2 floors, when the router is located in the basement, since the radiation is dropping to zero directly above and below the antenna.

That's any antenna that's not directional... No ?

2dbi has 360 degree though.

I had order it
http://www.ebay.com/itm/New-Dual-Band-2-4-5-8Ghz-9dBi-RP-SMA-High-Gain-Antenna-/130729553117
on Sunday and I'm going to return it back tomorrow.
Why? It's easy to explain. Even on 2.4 band stock antennas work better.
On 5GHz this "Dual Band High Gain" antenna doesn't work at all !!!
O.K. At the first I ask myself - May be the antennas very sharp directional?
I put router on the floor and walk around inside room and outside to house,
went up to the second floor and gone down to basement,
to try to find the maximum and minimum points...
I was trying to change positions of antennas of router and turn my laptop right-left, up-down... l lift and put laptop on the floor.
Of course I saw changes on inSSDer and they were different in different places.
BUT almost always worse or same like with stock antennas.
I couldn't believe... I don't want believe to it...

I walked around same way and did measure the level of signal in same points
three times for 2.4 and two times for 5GHz band and wrote down the figures...
And with each next time I was more and more sure that my new "double-band-high gain antennas"
ARE "not-double-band-not-high-gain" and only chip chines fake.

OK.
It's only MY my results.
And I really very hope, that others have good experience with this.
And may be the reason for such terrible results only personal myself.

P.S. I had conversation with seller and asked him about the model etc.
he told me that he has information from his diller and if I want I can return this antennas back
any time.
I knew the risk =chines+chip+no name of model+no name of manufacturer+no any warranty...
That experience cost for me a several dollars for shipping.

P.P.S I have two antennas http://www.trendnet.com/downloads/list_subcategory.asp?SUBTYPE_ID=859
(directional) and they works with good results with other router.
Now I'm looking for
http://www.trendnet.com/products/proddetail.asp?status=view&prod=105_TEW-AI75O&cat=91 ...
or similar but with any warranty against fake

I bought a similar product on Ebay. And I got the same result. Worse 2.4GHz band reception and nothing at all on the 5GHz band.

these antennas you are "looking for".. they seem to be for A/G.
dont you need N/G/B ?

 

[ArCan]

these antennas you are "looking for".. they seem to be for A/G.
dont you need N/G/B ?

For antennas doesn't matter what kind modulation will transmit or receive.
For antenna the important parameters are frequency, SWR and resistant
for compatibility with output of transmitter.

A/B/G/N/AC or FM/AM these characteristics doesn't important for antennas at all.

And I'm looking for DUAL band WiFi antenna it's mean 2.4GHz/5GHz, >3:1 SWR, 50Ohms...
Usually good antennas has >2:1 and resistance close to 50Ohms with resonance in centre of working band...

If I see A/G it's mean for me that it's antenna for both WiFi bands 5/2.4
and it's mean that such antenna WILL works with A/AC on 5GHz and
B/G on 2.4... and standard N of course that can be using on 2.4 and on 5Ghz...

I think...

P.S. For manufacturing antennas for such high bands like several GHz
very important the sizes each part of antennas and differences in couple millimetres
could be dramatically important too.
In my case (with antennas that spoke above) I think they was made
with so so control of measuring tools and materials (cable for example)...
On such frequencies the level of reduce of signal (-dBi) in bad cable (or materials)
could be same like the amplification (+dBi) of antenna and we will have 0 as result
and plus wrong sizes of part of antenna...

Hello everyone.

I was wondering if anyone know where to buy the antennas that are exactly the same or identical in specs to the stock antennas for an ASUS RT N66U router. I suspect that my antennas might have broke due to overheating.

I'm not sure if writing an email to ASUS support about aquiring another set of stock antennas would work (I have an account as asustek, so if I do email them about getting new antennas I would already be a verified owner -- but sadly, I did not buy a warranty from them). In addition, I live in Canada, and a lot of sellers of antennas only ship in the US - so I'm not sure where I can get my hand on a set of identical 2dBi stock antennas from all the way here, up north.

If anyone has tips or any suggestions and can share them, I would greatly appreciate them.

Regards,

Kuby.

Thanks for posting your experience its very useful sharing such things for the other ppl planning to buy such stuff, as a thank you I will post my experience

I bought a single band antenna of asus themselve the link below here

http://www.amazon.com/dp/B0046HQKV6/?tag=snbforums-20

I have not seen any improvement in the 2.4Ghz infact it was worse, and one day while reading I think one of toastmaster articles about antenna I learned that those high gain antenna,s only have an positive effect when going horizontal meaning at the same floor, vertical signal will decrease so between floors it becomes weaker. Anyway it was a good read, and my test though unsuccessful was still a joy for me crossing down oan "IF" out of my mind
