MLA-T
The MLA-T can be used indoors with a maximum input of 10 W. With higher power, never use MLA-T as a
room antenna, with which you would want to run a round-the-clock contest! Limit your exposure to the RF
magnetic field to a necessary minimum. With more than 10W input, operator shouldn't be located near the
loop! The RF magnetic field passes also through walls. While the side effects of RF magnetic field component
have not been proven by science, stay safe and keep also others in a safe distance.
Do not touch the antenna loop under RF power, it can cause RF skin burns or even death. Expect EMC
problems to surrounding electronics as the usual screens are not efficient for high-intensity magnetic field
component. Individuals with pacemakers and similar implants should never approach a running MLA-T.
The MLA-T Magnetic Loop Antenna was developed following a marketing evaluation of the indoor MLA-M
type which was designed or QRP operation. Repeated requests and interest in a remotely tuned higher-power
antenna for Top Band operation stimulated the development of MLA-T. A reserved view of a MLA-T located in a
concrete-building basement indicates that such antenna cannot compete with a dipole stretched between two
such buildings high above ground. Nevertheless we believe there are many situations where the new MLA-T
can find its customers.
