Ham Radio Antenna On Metal Roof

I would consider a vhf uhf antenna over a huge metal roof ground plane similar to an hf antenna over earth ground.

Ham radio antenna on metal roof. But the benefit of this larger roof mounted antenna is that now we can leave the radio on all the time and listen to it inside which leads to more opportunistic connections and overall more time spent enjoying. It would likely make a lousy antenna. The metal roof acts as a shield so rf exposure is a non issue. A 5 6 tripod with cement block weighted legs and a 10 pole in the center of the roof would work since the bottom of the antenna only needs a few feet of clearance.

Long wire antennas look at the long wire antenna on the roof. For mounting i d leave the 18 pole alone. I am concerned about the impact a metal roof will ham radio antennas and metal roofs 11 30 2004 within the reception discussion of the residential metal roofing forum. When its lower than a few wavelengths and at multiples of 1 4 wavelength like 1 4 3 4 etc the pattern of a vertical antenna can be pushed upward and away from the horizon a bit lowering its gain at the horizon.

On using a metal roof as an antenna the joints between panels are likely not soldered and are likely to form corroded diode junctions that generate rfi. You can probably get as close as a quarter wavelength and still make things work with some adjustments to the tuning. As an ultra beginner without a lot of investment in the hobby it was perfectly acceptable to have to climb onto the roof to get any signal on my portable radio s antenna. It runs up the front of the roof on the left as you face the house then runs across the roof along the ridge vent plastic construction then down the back of the roof to the eaves at an angle.
