I'd be worried about the SWR of home-brew designs, too high and it can
blow up the transmitter.
I think the original question was can the antenna be taken off the
Access Point and an external antenna used instead.
The simple answer is yes.
The length of the cable between the access point and the antenna is
important and it is best to keep this to 5 metres using something like
LMR400 or RG58. LMR 400 will give the lowest loss so for long distance
communication use it. It costs around £2 per metre and it is best to
buy it ready made. The best you can expect with a 12dbi antenna is 500
If the AP is in the loft then use UPC to go to the network card in the
We are presently installing lots of these systems to distribute Wireless
Broadband around rural communities.
If you need any further help drop me a line direct. You can pick our
brains for free, providing you can find them!
