Worked 2 of my 1000 mile/watt awards with an attic mounted 1/2 size G5RV (mounted at the ridge) with normal shingles. It actually proved better on 40 than an outdoors 134'6" wahr/9:1 unun. Mu current location has a metal roof so I'm going the "ground mounted vertical" route (as soon as the rain stops!)
Be blessed all,
