cloth or metal antennae box cid If that metal 'box' shields the antenna from receiving a signal it just isn't going to receive very many signals. So getting the antenna outside of that metal 'box' would be a very . But what type of metal building insulation is best? Let’s start with the basics. Obviously, metal is different than wood in the fact that it conducts more heat. Depending on the specific design, it may often keep cold air in during the winter.

As more and more electric lines are buried in neighborhoods and throughout your local electric co-op’s territory, more big green metal boxes — about the size of a mini fridge — are likely to be seen. These are pad-mounted transformers.
If that metal 'box' shields the antenna from receiving a signal it just isn't going to receive very many signals. So getting the antenna outside of that metal 'box' would be a very .Most likely no. We design our products for the antenna to be on a placed away from metal or components like LCDs. If etching the antenna on the pcb is not possible then we use pigtail .

Paint can, cheap, and readily available. mild steel shields down to basically DC. Copper and aluminum sheet or screen work to pretty low frequency. look up "skin depth" to determine how low you can go.. even thin foil in plastic works above a few KHz.

If that metal 'box' shields the antenna from receiving a signal it just isn't going to receive very many signals. So getting the antenna outside of that metal 'box' would be a very nice thing. Or, you could turn that metal 'box' into the antenna. Most likely no. We design our products for the antenna to be on a placed away from metal or components like LCDs. If etching the antenna on the pcb is not possible then we use pigtail antennas with sticky tape. A last resort is for the antenna to be protruding the case or mounted outside the case.
Normally AM radios use a magnetic loop (ferrite rod antenna) for picking up the H field part of the electromagnetic wave they are trying to receive: - A closed box of steel isn't going to substantially prevent the H field penetrating inside. The Faraday cloth creates a continuous and uniform ground plane, which can enhance the antenna’s performance. It’s particularly useful for reducing ground losses, which is a common issue with vertical antennas. If you have a rooftop antenna, it probably has steel, aluminum, and plastic. Your indoor antenna might have all three, too. Why are there so many different materials used in antenna manufacture, and which is the one you just can’t live without?
Three 10-foot rolls of hardware cloth serve as a ground screen around this end-fed antenna that has been converted to a ¼-wave vertical. How big should the ground screen be? As mentioned earlier, mesh within 1/8th of a wavelength around the antenna will do a great job of reducing ground loss. 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. The region around the antenna where metallic objects will have the most impact is within the "near field". This distance is directly proportional to wavelength, and varies depending on if the antenna is electrically short or long. My concern is that the galvanized steel mesh presents greater resistance than would copper wire radials. At the same time though, I could lay down a lot of metal on my ground plane at no cost. What are your thoughts or experiences regarding steel .
