mobile 2m/70cm used as base

I am wondering if a mobile antenna (2m/70cm) with a mag mount stuck to the flashing on top of my chimney would work. The flashing is 2-1/2' x 4'. Would that provide enough ground plane if the antenna was placed in 1' x 1' from the corner? The furnace vent is in the center. Thanks

Sure, it will work. How well is the question. I have heard of many hams who mount a mag mount to a pizza pan or an air conditioner unit and get out just fine. I know it will be a lot better than an ht, and many use them exclusively with no problems. Give it a try.
