The magnetic loop antenna, MLA-C, has been modified and optimized by computer modeling, to achieve an optimum size and efficiency. MLA-V is designed for operations at 3.5, 5.3, 7, 10, 14 and 18 MHz, with input power up to 100 W. It is tuned remotely by a DC motor driving a high-voltage variable capacitor, by a CB4M driver unit using an intelligent PWM mode.
At 3.5 and 18 MHz, operation is slightly compromising. At 7, 10 and 14 MHz the antenna offers very good results even in DX mode. MLA-V KIT is the newest of the series developed by OK2ER. It is preferable for /m and /mm operation, but it works well in any mode. It can be completely disasssembled and reassembled anywhere where transporting the assembled MLA-C would be impossible. Therefore it is ideal in crowded lofts with a limited access.
Antennas are delivered with individually filed test protocols.

The MLA-V (V as „veranda“ or a patio) is a new antenna of the series of magnetic loop antennas from the workshop of OK2ER.

MLA-V is a magnetic loop antenna for five (six) short-wave ham bands, 3.5 MHz, 5.3 MHz, 7 MHz, 10 MHz and 14 MHz (18 MHz). An important point is that contrary to other competing MLAs, the MLA-V can be used with 100 W RF input and needs no control cable. It is remotely tuned via the coaxial cable.

Like in other pioneer designs (Switching loop turns) to allow using a MLA-M over several short-wave ham bands, MLA-V covers also several bands which works virtually against laws of physics.

MLA-V is of course not an equivalent to a full-size 3 el. Yagi but without any doubt this tiny antenna (1.3 x 1.3 x 0.7 meter) can be well used during a vacation without explaining to curious onlookers that the antenna is not a worthless „strangeness and hobby“ of a Czech tourist.
With the MLA-V you will not disturb the public by hanging provisional wire antennas that actually would not function better than this new MLA-V. You can inform others that your MLA-V is a mobile laundry dryer, see the photo.

In MLA-V design, OK2ER applied his extensive experience learned in this special antenna field (magnetic loop antennas) over long years since 2009.
