Question regarding dual band antennas

post #1 of 3
Thread Starter 
I own an ASUS RT-N66U wireless router which has both 2.4GHz and 5GHz bands. I am wanting to purchase a set of 9dBi dual band antennas to improve the wireless network signal strength in my house. I was just wanting to know what the difference is between the three listings below? Would they be compatible with my wireless router? Why is there like a ~$4 price difference between listing 2 and 3? Also, does antenna length have an impact on signal strength (ex - 15.2 inches fully extended and 14 inches folded vs 15.7 inches fully extended and 14.5 inches folded)? Any help would be much appreciated. Thanks in advance!

dBi gain, H-Plane and E-Plane are usually what you'd be looking for. Not sure what kind of elevation plane those would have although they are omnidirectional. Length is fairly irrelevant compared to dBi value, although you may find higher gain antennas are longer/beefier.

You'd need either 2 or 3, the router you have has RP-SMA connectors. Not sure for price difference, although one specifically states dual band in the title and the other does not.

What concerns me is that in listing two and three the antennas are listed as 2.4 Ghz ~ 5.8 Ghz antennas but the word "dual band" is not reflected in the item name in the second listing whereas it is in the third listing. Is it safe to assume that the antennas in the second and third listing are both dual band? Thanks.
