Thanks for that link, I'm having a look now.

No, writing a cheque means bugger all.
I just had a look at that URL and the hardware they're using looks 
familiar. I wasn't sure if I could use RG-213, Beldon or some other 
lower-loss coax cable but it looks like they've used that, with N-type 
PL-259 connectors, so that's no problem. If that is a PL-259 I can see, 
they would've used N-type instead of standard PL-259 to try and avoid 
coupling losses because when you're dealing with frequencies in the GHz 
range antenna coupling's are usually a signifacant portion of a 
wavelength, which causes the coupler to radiate signal instead of the 
antenna radiating the signal.

QSL, thanks again I'll check it out.
