Antenna for 2m/70cm, Diamond X-30N, mounted on roof of dormer
Parts for mounting the
Diamond X-30N which I bought in October
on the roof were collected in the months since October and it was finally
clear enough weather for a fellow radio amateur with lots more climbing
experience and the right gear to climb on top of our dormer and install
There are rubber granulate pads on the roof to avoid damage, a metal frame
sold as a mount for satellite dishes to which the antenna is mounted,
4 concrete tiles in the mount to weigh it down on the roof. The coax enters
the house alongside a chimney.
After the work on the roof it was good to drink a beer to celebrate and
afterwards I routed the cable further to my shack.
The first fast test was calling CQ on a local 2 meter frequency and someone
from my radio club answered immediately.
The second big test was participating in a radio roundtable held on Sunday
evening. This went fine, net control at a distance of somewhat over 30
kilometers gave me a 55 report (audio readability 5 and signal level 5). So the
antenna is clearly doing what it is supposed to do. It's also nice to see
the base noise level on the 2 meter band is near zero.
