Up your area. It is at Wiruna.
I use the 3rd harmonic from a hand held CB for testing. Its frequency is 1429 Mhz. However the spectrum analyzer is calibrated and can see -117dbm at maximum sensitivity. The LNA givers an additional 30 db and the dish should eventually add another 24 db when it is repaired.
The spectrum analyzer is old but good, a HP 141 main frame with 8552B and 8555A plug ins. It is at Wiruna
I also have an 8558 Spectrum analyzer (1 to 1500 MHz). I have this one at home for testing but it is not as sensitive.

PS I have built transmitters and receivers for the 1296Mhz Ham band 45 years ago when we had to work with valves. I was the first one to get a working system going and as I was "The contest Committee" I organized a contest with cross band allowed and naturally the scoring was biased my way. However I let Dick 2ZCF have my receiver and he eventually won.
