  • simple, basic antenna

    posted by Mariusjunior on 13:39:42 G2T 08/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Feels as massive, good quality. Very cheap antenna.

    Cons: I can't turn the wheel on this antenna. So, when I screw this antenna on the router, the antenna point to a total wrong direction! So, I have to screw it back a little, but then the antenna is loos and not tight. That's why I only gave 3 stars for usefullness.

    Other: If I knew that the screwingwheel is fixed, I would look for an antenna wich is a few dimes more expensive. But for now, I am glad I found a fitting and working antenna.

  • Weaker than a 2dBi antenna

    posted by ET3D3D on 03:24:12 G7T 17/07/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It works.

    Cons: It works worse than the 2dBi antenna that came with my router.

    Other: If you just need a replacement antenna, it'd work. If you expect a signal boost, you'll be disappointed.
    (And BTW, it'd be nice if the review form said how many characters I'm missing to get to 500.)

  • affordable replacement antenna

    posted by axlety on 17:13:04 G3T 22/03/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The antenna is cheap and it works. It can lock in 3 positions. Big and heavy - looks strong.

    Cons: Does not offer any signal improvement over stock antenna. In fact, it is even slightly worse!
    The connector is metal, but is painted with non-conductive paint, so the shield is probably not connected.
    Was shipped without any packaging or documentation, only with some paper label, that was extremely difficult to remove.

    Other: Buy it if your antenna was broken/lost and you need a cheap replacement.

    posted by redhawk89 on 03:00:55 G3T 06/03/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: -Plugged this device into the back of a linksys wireless and it finds the router which is downstairs. This is a significant upgrade over not being able to find the router.

    Cons: -I cannot think of any con. The only con would be to not buy this item. You should buy it if you just need some sort of simple solution like I did.

    Other: I like internet access, so I like this device. I am really glad to be able to use the internet again after so much time not being able to use it.

    Involvement Level: Expert (understands the inner workings)

    Pros: a nice antenna, a bit stronger than the stock antenna =) works well on my FON router =)

    Cons: none where i can think off, works like a charm

    Other: if you want to replace a stock antenna and you don't want to spent a lot, this will do the trick :) and it is probably better than your stock antenna :O

  • Enoth for general use, but its not what specified

    posted by Sysmatck on 17:25:10 G9T 08/09/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The antenna works very well, the price is realy good, and the material seems like all others of the same kind.
    The antenna is a litle bigger than a 2dbi antenna and a litle smaller than a realy 5dbi one

    Cons: I don`t think the specified Gain (5 dBi) is true. In my tests this antenna could not issue better signal than my 2dbi antenna (original router)

    Other: The wireless antennas must have a very good material because of the caracteristics of this kind of signals. The recomended impedance is 50 ohms. Maybe this item don`t follow these stuff rules

  • Great replacemet Ant for WiFi cards

    posted by nightshade on 05:13:15 G7T 08/07/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a exact replacement WiFi Antenna for my Linksys WRT54GC and EdiMax card. It works great but the range is no better than the original antenna. It is still a very cheap replacement antenna as the original antenna from Linksys would cost at least 5 time the price we paid at dealextreme.

    Cons: Was hopping that this could give better DBi but for its price, I cannot complain.

    Other: Since it is very hard to get a replacement Antenna for the Linksys WRT54GC, this is the best solution.

  • Changed over to RP-SMA

    posted by cctsmaster on 07:05:39 G7T 01/07/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: * Has three locking angles
    * Solidly constructed connector
    * RP-SMA connector, not RP-TNC as mentioned previously. Your experience may vary.
    * Uh... it's black?

    Cons: * Squeaky and rattly
    * RP-SMA connector, I ordered it hoping for a RP-TNC... sigh. No real use for a RP-SMA myself.

    Other: As mentioned, it's apparently now a RP-SMA, not RP-TNC. Take that into account - there is no guarantee that you'll get the connector you want.
    DX doesn't have any other RP-SMA or RP-TNC antennas of this type either, which is a bit of a shame. Consider buying an adapter; DX doesn't seem to carry one either, sadly.

  • Basic antenna with wrong connector

    posted by kevredon on 09:54:24 G11T 16/11/2007 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: A cheap basic antenna (not more then +2 dB) for routers without internal antenna

    Cons: It the wrong connector. The product claims [RP-]SMA, but it's RP-TNC

    Other: Be aware of the connector, the true connector is RP-TNC, not SMA

    posted by InvisibleSoul on 19:37:44 G11T 01/11/2007 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Using NetStumbler to get a more reliable reading, here is what I found. With DD-WRT on an old WRT54G v2 using single antenna mode, I found that one of the two antennas I bought is defective. With no antenna attached at all, the signal/noise ratio was 40. With the default antenna, SNR is 58.

    With the defective antenna, SNR is only 42.

    With the working antenna, SNR is 70 - a definite improvement.

    Also for reference, with an official Linksys HGA7T high gain antenna, SNR is 75.

    Cons: Not very good build quality.

    Other: Good replacement antenna, but don't expect too much of an improvement over the stock antennas.
