>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.

>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.
