If you want to make existing access point more directional, you could
try this

You'd be better off getting another Access point and relaying the one
you have. Unless you want to improve the range of this existing system
in -One- direction i.e. focusing the power you have rather than
broadcasting it then any additional aerial you add onto the existing
ones isn't likely to make it any better..


BTW .. Aeriel is spelt Aerial ;!...

If, as Tony says, you can live with a uni-directional aerial - depends, of
course, on the location of all receivers wrt to the transmitter - the corner
director in Andy's link should do the trick and costs virtually nothing.

Forget about velocity factors and coat hangers - anything you come up with will
be worse than you've already got, unless you built a well designed multi
element directional aerial at considerable expense ...

Note the important words the 'well designed' 'directional' 'expense' and
compare with about fourpence for the much better corner reflector with proven
performance ...

Otherwise follow Tony's advice ...
