Dick Smith et al. don't realy have the type of cable you want. They 
have RG213 but that is very lossy.

I just checked the rsaustralia  site, couldn't find the confirmable 
microwave cable but looking at some of the cable they are selling
it's pretty expensive ( like really really expensive ).

LMR 400 should be something like $5 a metre + about $10 per each 
connector.
Try looking somewhere like freenet antennas,  rfshop.com.au , ebay or 
ask Vak if he can make you up one.
If you go to the next meeting you may find Dan has some pre-made cables 
he is offering to sell

shop around, but remember cheap may not be best, the type of cable and 
the cable loss can make a big difference, especially
when you are talking about a long run ( 10M ). Most people would be 
looking for ways to reduce the cable run length like putting the AP in 
the roof near the mast, or even in a waterproof housing on the mast. 
Look on the wiki for some examples and also some good info on coax and 
the different types that are useable.
