Previously I had tried to get someone to put it on the roof of the house but it's a two level roof with very steep sides and, apart from being dangerous for the installer, it would have been impossible for me to get up there to do any maintenance.
Mounting the antenna on the flat roof of the garage means it's easy to work on. The drawback is a longer coax run. Tests so far show excellent signals from repeaters around Melbourne.
Currently I'm running WSPR and only hearing VK3DXE. I'm transmitting 10W and so far no one has spotted me.
The focus for now is 2m but I've also run two pieces of RG58U out to the back yard with the intention of adding a 20m dipole and whatever else I can come up with in very limited space.
I should add that I did not do the roof climbing but merely supervised. Here's a picture Phillipa took showing the limit of my management.
The 2m antenna is working well and tonight I had simplex contacts with Ralph, VK3ZZC and Chris, VK3AML.
