I'm trying to make an extension cable for the antenna from my wireless router

This is the wireless router I have:
http://www.newegg.com/Product/Produc...82E16833704038

You can detach the antennas. Since I want to set this up in a 4 bedroom apartment and don't want multiple routers or extenders, I think placing the antennas in different rooms would be best.

The connector is RP-SMA. I checked online and the cable is RG58u, I believe. However, I have access to (much better) RG56u cable because I will be running cable lines throughout the apartment (hidden in the wall). Is it possible to use RG56u cable to extend the antennas throughout the apartment and crimp the ends with RP-SMA connectors?

Has anyone ever done anything like this?

I use a 20ft WIFi Cable Extension (bought on ebay) on PCI desktop wireless card, I believe I get much better reception... that all the experience I have...

like running a marathon while breathing through a straw...

you need LMR 195 or LMR 200 for runs up to 20 feet and LMR 400 for anything longer

Thanks. LMR has a lower loss rate? Bandwidth is the same? Also, 56U will not work at all?

I believe you'll break the MIMO feature of your router by separating the antennas like that. Not to mention you'll have a serious signal loss problem if you are extending the antenna by more than a few feet without some pretty hardcore cabling (LMR200/400).

http://en.wikipedia.org/wiki/MIMO

In (single-layer) beamforming, the same signal is emitted from each of the transmit antennas with appropriate phase (and sometimes gain) weighting such that the signal power is maximized at the receiver input...

Spatial multiplexing requires MIMO antenna configuration. In spatial multiplexing, a high rate signal is split into multiple lower rate streams and each stream is transmitted from a different transmit antenna in the same frequency channel....

Why reinvent the wheel? Multiple access points is really the right way to do this...

Big mistake to use at the WIFI frequency Antenna coax longer than few feet.

The decay of the signal with distance is very sharp.



:cool:

I guess this isn't such a good idea then. My only other option would be to setup two wireless routers since the apartment is large.

Yeah two or three will do.

If your Wireless is capable for simultaneous AGN then it will work great.

what is the problem you are having in this apartment?

what are the distances / materials you are working against?

is someone just microwaving chimichangas all day? :)

if the rooms you want to cover are all on the same floor, using a higher gain antenna is a better option I would think that getting a antenna extention.
