>Hi Everybody,
>This morning (29th Nov) at 0900 a brand new RFI Folded Dipole antenna
>was installed on top of the tower at the VK5REX B D-Star repeater site.
>I was able to utilize a rigging company that was in town on another job
>which saved me any travel costs. The riggers were delayed a few days
>because of the inclement weather and were more than happy to help me out
>before heading back to Adelaide. The two guys who climbed the tower had
>it done within an hour. The existing ex-Austar MDS cable was used and
>the antenna plugged directly into a 7/8" EIA flange to N type adapter.

>Because of the ongoing isolation issues with the current duplexer, I am
>currently running VK5REX B on a two antenna setup. The existing antenna
>is now the transmit antenna, and the new antenna on the top of the tower
>is used for receive.

>Initial on-air (non scientific) tests show a marked improvement on
>receive performance. I can use low power on my IC-91AD radio from
>anywhere inside my house where as before, I would have trouble even
>using high power. In coming weeks I will be performing DX receive tests
>to see how VK5REX B is now performing.
