Unfortunately the antenna is situated just at the top of my house’s roof so it does not provide a great coverage. But it is still better than nothing! And the repeater provides a very good coverage inside of Portsmouth, when I walk with my handheld radio.

Repeater restarts automatically every night 03:00 AM … 03:01AM
