2-meter mag mount antenna used on sheet metal The sheet metal would need to be at least 1/4 wave length radiating out from the base, so for 2 meter VHF, 19" in all directions, or 38" across. Then there's the issue with what . Benefit from a second key, which can be used by co-owners or as a backup set in case of loss/misplacement. ADJUSTABLE SHELF HEIGHT: Four of the five shelves in this cabinet are adjustable, guaranteeing maximum adaptability and convenience for your own unique storage and organizing needs.

Milbank NEMA 3R enclosures are designed for either indoor or outdoor use and provide a degree of protection to internal equipment against water (including rain, sleet and snow). NEMA 3R enclosures are also designed to be undamaged by the external formation of ice on the enclosure.
The sheet metal would need to be at least 1/4 wave length radiating out from the base, so for 2 meter VHF, 19" in all directions, or 38" across. Then there's the issue with what .The mag mount is not working great as the ground plane is not big enough. These antennas are meant to be on top of a car roof, not a small cookie sheet. At 144Mhz, the wavelength is 82 .A mag-mount antenna is grounded through capacitive coupling between that magnet and the metal it's stuck to. At VHF/UHF frequencies, this effect is adequate for good results which .
My trusty antenna analyzer has shown me that you really want 19" of metal on at least one side of the antenna. If your metal sheet is that size or smaller you'll get better performance sticking .
In general, the radius of the thing the mag mount sits on should be at least a 1/4 wave in length (and you seem to have a 1/4 wave antenna for 2 meters). So for you, a 20 inch radius metal .Mag mount antennas use the car they're attached to as a ground plane. If you have it sitting on a shelf with no metal for a ground plane this antenna will not be effective. Attaching the mag .
Attaching an antenna to a metal roof probably won’t improve or hurt reception. Yes, practically anything made of metal can be used as an antenna in some way. However, .
I use a 2 foot x 2 foot piece for both GMRS and 2 meter ham work with a 50W radio. Exposure to RF is an issue you need to guard against. There are calculators available . I placed a mag mount Tram dual bander on a window unit ac, and later on top of a 25ft steel tv antenna tower. In both cases I hit repeaters up to 50 miles out with 50 watts or . The sheet metal would need to be at least 1/4 wave length radiating out from the base, so for 2 meter VHF, 19" in all directions, or 38" across. Then there's the issue with what grade and how long the coaxial cable would be. Magnetic mounts are usually intended for mobile use, and will have a short length of RG-58 coaxial cable.
The mag mount is not working great as the ground plane is not big enough. These antennas are meant to be on top of a car roof, not a small cookie sheet. At 144Mhz, the wavelength is 82 inches (~2 meters). These cookie sheets are only 19in in the . My first HF contact was made between San Diego, Ca and Florida on ten meters using a mag mount CB antenna placed on the roof of a metal storage shed. Yeah, metal roofs can help. A mag-mount antenna is grounded through capacitive coupling between that magnet and the metal it’s stuck to. At VHF/UHF frequencies, this effect is adequate for good results. How do I figure out the dimension size of the antenna’s ground plane?
A good ground plane doesn't have to be ferrous metal, it just has to be conductive, and preferably extend 1/4-wave or so in all directions from the whip. But if it's not magnetic, you'll need some other way to mount the whip, which goes back to just getting a base antenna anyway.A mag-mount antenna is grounded through capacitive coupling between that magnet and the metal it's stuck to. At VHF/UHF frequencies, this effect is adequate for good results which explains the popularity of these mounts. My trusty antenna analyzer has shown me that you really want 19" of metal on at least one side of the antenna. If your metal sheet is that size or smaller you'll get better performance sticking the mag base on the edge, not the center.
In general, the radius of the thing the mag mount sits on should be at least a 1/4 wave in length (and you seem to have a 1/4 wave antenna for 2 meters). So for you, a 20 inch radius metal plate. Mag mount antennas use the car they're attached to as a ground plane. If you have it sitting on a shelf with no metal for a ground plane this antenna will not be effective. Attaching the mag mount to a baking pan and then placing it on the shelf should work for a ground plane.
Attaching an antenna to a metal roof probably won’t improve or hurt reception. Yes, practically anything made of metal can be used as an antenna in some way. However, unless something is designed to be an antenna it will work so poorly that a “real” antenna won’t be affected by it at all. The sheet metal would need to be at least 1/4 wave length radiating out from the base, so for 2 meter VHF, 19" in all directions, or 38" across.
