The MLA-ER is a small-size compromise design of a short-wave magnetic loop antenna (by OK2ER),
suitable mostly for portable activities such as an urban QTH. It can be used in locations where other gain
antennas can not be used, such as a balcony, indoors, or from a loft.
This design is lightweight, is easily transportable, and (contrary to other antennas) it needs no ground
connection or counterweight. In its price, frame the MLA-ER is probably the unique commercial MLA
that can operate under a full 100 W power input available from commercial transceivers. The MLA-ER
is also an ideal antenna for vacations as it can be run from a hotel room with a reduced input power.
