9db upgrade antennas on ebay - worth it?

Prolly help with distance, but signal strength too? Here's the link.

good question

+1 what will these really do for this router?

just order going to see what they do, ill have them between the 5th and 7th...

Coolio. 'Look forward to your review.

 

[nowknown]

here's some good info from a SNB article about add on antennas.

HI,
Gain figure may be higher but certainly it won't have same vertical/horizontal radiation pattern/angle, SWR figure. Result unknown until you try it out.

Ant-157

I was shocked how this directional antenna improved the 2ghz and 5ghz performance of my RT-AC66U. I replaced the center omni-directional antenna with the ANT-157 and it filled in all the weak and dead spots on all three floors of my home. The router is installed on the middle floor at one end of my house, so a directional antenna works great for my application. This is certainly a better solution than installing a repeater on the other side of the house.

Could you not specify figures regarding signal strength before and after
you replaced the antenna ?

I have replaced the antennas on my AC66U with these ones and can see a gain of about 6 dbm on the 5 GHz band but on the 2.4 GHz band it is a weaker signal of about 8 dbm. It certainly catches eyes as these antennas are much longer than the standard ones.

Has anyone managed to buy this antenna in EU?

Here's a perhaps relevent quote from the ubove linked SNB article regarding this,

"Radiation Pattern

This factor is as important as gain in determining whether a specific antenna is right for you. It determines the directivity or coverage area of the antenna, and if chosen incorrectly can make your wireless connection worse!"

 

[mikeg]

Actually I wanted to test if I would get a stable connection to the 5 Ghz band with my laptop 2 meters away from the AC66U or not. Theory is one thing , real testing is another more practical way to see how things will work. As it turned up the connection did not improve in stability at all on the 5 GHz band.

I highly recommend these

Worked great for me, didn't effect 5ghz.

Did you replace all or just the middle one?

 

[claymoh]

Are you sure that is the right one? Seems like both it and the Asus are males?

This is the wrong antenna for the RT-AC66U. This antenna impedence is only for 2.4ghz. You would kill your 5ghz using this, and possible damage the transmitter.

You have to get a replacement antenna that is made for dual band. Asus makes their own that will work for dual band.

I replaced all 3 antennas on my n66u with
http://www.newegg.com/Product/Product.aspx?Item=N82E16833997226

I hope they make a dual band one. But I don' think it is effecting my 5ghz though my signal has been jumpy though I think that happened when upgrading to the latest firmware.

How can an antenna be tuned to 2 bands? How is it different from a 2.4 only antenna? Hope I dont blow my 5 ghz tx.

 

[netmik3]

I found this http://r.ebay.com/9yBERk but I don't know if I believe the dbi nor the dual band.

 

[italyguy01]

I tried the "Asus" 9db dual band antennas that amazon sells. No markings of Asus on them anywhere.

I sent them back, Did not make any difference at all.

 

[netmik3]

italyguy which ones? These? http://www.amazon.com/dp/B005UBNJ48/?tag=snbforums-20

italyguy which ones? These? http://www.amazon.com/dp/B005UBNJ48/?tag=snbforums-20

Yes I tried one of those, and didn't do anything for 5ghz at all.


Then I tried 3 of these and no difference:
