There are eleven cavity filters at the VK6RMS site.
On the left is the voice repeater's duplexer consisting of 6 cavities.
In the centre are two cavities,
one for the voice repeater for filtering against pagers
and the 2 metre digipeater,
and the other for the 2M digipeater
also for filtering against pagers and the voice repeater.
The two large black cavities are the 420 - 440 MHz Duplexer
for the packet link.
Both these packet systems are duplexed onto one antenna,
along with the 2M packet digipeater.
Behind the two black UHF cavities is a single UHF cavity
for receiver filtering
of the voice link receiver used to link VK6RUF from Perth
to this site.
The two small colourful cavities right at the front are for insect filtering.
There are only two amateur antennas
on the site,
both being dual band 2M/70CM
GST-1's
These two antennas provide for
the 5 receivers and 5 transmitters on site.
