I have a friend with the gigabyte ga-h77n-wifi motherboard and the default wifi antennas for the board are pretty average. I'm looking around for him to find something that would fit. Not being able to see the board I can't tell what size they are etc.

I'm looking at this TP-Link antenna at PB Tech. Just wondering if anyone knows if it'll fit?

The main issue here is checking if the connectors will fit. WIFI typically uses the SMA coax connector however some times the inverted version is used (R/P SMA) http://en.wikipedia.org/wiki/SMA_connector

once you know the needed connector type have a look on here

On the shopping link provided by resurrect I would recommend you get an antenna with the thicker style coax lead, and as short of a lead as practical.

I got an 8dB TP Link Antenna, similar to that antenna you linked for my brother, and it didn't improve the signal much. http://www.pbtech.co.nz/index.php?z=p&p=NETTPL2408&name=TP-LINK-TL-ANT2408C-2.4GHZ-8DBI-Indoor-Omni-Direct

After a bit of scratching around I discovered that the weakest link in the system is the thin coax. Typical RG174 attenuation loss as per link is appalling at high frequencies.

http://www.westernwire.org/CoaxSpecs/WRG174XX.pdf

They don't even bother listing the 2.4 GHz loss, it is so bad. Remember that 3dB loss = 50% of the signal lost. Flexible, thin coax simply can't carry 2.4 GHz and 5 GHz signals efficiently. (I don't know why mfg's use it).

I chopped it off and replaced it with bog standard RG58 50 ohm marine coax and got a noticeable improvement in signal. Even though RG58 isn't ideally suited, it is less bad that the thin stuff.

If your mate is a gamer, or pushes big files over the network, and the physical situation allows for it, talk him into using a CAT5/6 cable. That's what we did in the end, and it was so much better than a shonky wireless signal.

Edit: Also, don't forget the Wireless AP antenna. If it has external antenna connectors, you can improve the signal strength at the client by fitting a high gain antenna to the AP. You can get some highly direction panel/yagi antennas, and a pair of those pointing at each other will make a huge improvement over omni directional antennas.
