Can you ground a magnet mount antenna?
Can you ground a magnet mount antenna?
There’s always a ground. Whether it’s what you intend it to be or not is another issue… 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.
What is a magnetic antenna?
The magnetic loop antenna measures the magnetic field (H-field) emanating from the EUT. Measurement of the H-field is often specified when RE testing below the normal 30 MHz lower frequency point is required by the product standard.
Do antennas have magnets?
The alternating current of the antenna creates a weak but very real “vibrating” magnetic field around the antenna. A magnet placed close to the antenna has it’s own magnetic field which interacts with the magnetic field of the antenna.
Do magnetic mount antennas need a ground plane?
Since aluminum doesn’t have any ferrous metal in it, the magnet isn’t going to stick, but that’s OK. In an attic, all it’s got to do is sit on top of the aluminum to achieve the capacitive coupling it needs to utilize the ground plane.
Does a magnetic CB antenna need to be grounded?
Usually this surface is part of the vehicle (roof or trunk) which is at the vehicles’ electrical ground and thus can make more of the vehicle part of the grounplane. The antenna itself does not need an electrical ground.
