Router Antennas

Does anyone know what advantage I would get from using large antennas on my router? I have ordered 2x 16dBi antennas and was wondering what difference it will make in terms of wireless range. They're 38cm in length and omni-directional.

Thanks!

Re: Router Antennas

I've bought 2 of these: http://bit.ly/UPIng9

I will be fitting them to a DLINK DIR-615 and want to eliminate the dead / weak spots in my house. Currently when you go to a corner of the house the signal drops quite bad and becomes slow.

Re: Router Antennas

have you checked whether the 615 you have or rev. has the ability for the owner to simply unscrew the antennas off? don't pull or the hard wire will come out with it.

Re: Router Antennas

I will have to check on Monday, but if not will it be as simple as to de-solder the old antennas or a little more complicated?

Re: Router Antennas

more complex and also could prove a problem for the router itself (over heating)

Re: Router Antennas

Revision D2 as U.FL connectors for replacement antennas/pigtails, revision D4 has the antenna cable soldered directly to the mainboard.

Large antennas focus the signal in one direction. Indoors, it's pretty pointless as most of the signal is reflected, and even if it weren't it'd only work well if you had a wide, flat residence.

You'd also be breaking ETSI regulations, but who cares about those, right?

Re: Router Antennas

Is it the antennas that could cause overheating or using the soldering iron on it?

Re: Router Antennas

Ok qas, if the antennas are maxed out will the router overheat and will my health be at risk from such large antennas?

Max out antennas? What are you on about?

Router outputs fixed power. Antenna points it in a certain direction. Different antenna points it more precisely in a certain direction.

Nothing to overheat.

Though if you short the antenna connectors it probably won't like that, but all you'll get then is crappy performance until you connect them properly.

Only revisions D2 and D4 (the Virgin Media ones)

That said I still haven't managed to get the ethernet, wireless, hardware NAT and mesh networking to work on it at the same time. I kinda gave up and I moved onto more expensive kit.

Re: Router Antennas

The antennas I got say they're omni-directional and I have the D2 version.

Omnidirectional in the horizontal plane. Probably as omnidirectional as a pancake in the vertical plane...
