MLA-M V.5: magnetic loop antenna for portable use, 80-10m incl. 60m! MLA-M is a magnetic portable antenna for QRP operation. The rugged antenna has a diameter of 60cm and can handle up to 10 watt. The box contains the tuning circuitry.

Frequency range is selected by two jumper connections on top of the box. One jumper is responsible for the operation on 80m, while the other one selects 20-10m.

If none of these jumpers are connected, the antenna operates at 30, 40 and 60 m. The bottom side of the tuning unit has 4 rubber feet, so the antenna can be put anywhere without causing scratches of furniture.

Connector is UHF (SO-239), weight is 2.5kg.

The antenna is not 100% waterproof and so not suitable for permant outdoor installation without additional cover.

Retaining plate for stand construction

For mounting on a tripod there is an extra dapter for the MLA-M as an accessory available.
The plate is screwed to the tuning unit and inserted on the other side on the stand. Thus, the antenna can be rotated not only in the horizontal plane, but also the elevation to be changed, which is reflected in the targeted suppression of disturbances.

MLA-T: portable magnetic loop antenna 160-40m

The MLA-T is a magnetic portable antenna for 160m, 80m and 40m.
In contrast to the MLA M here is a stepper motor in the housing for tuning. On the radio now remains only the controller and the antenna can be placed deducted.
Also new is that the antenna can handle a power up to 100W. The power should not be more than 10W at a distance of less than 5m around the operator.

The stepper motor is powered directly through the coaxial cable, so no extra cable is required. On the controller are 3 LED for a simple and easy tuning. In addition, the stepper motor runs on each press on the controller slowly the first 3s to ensure accurate tuning.

The connection to the antenna has an N-jack. On controller 2 PL sockets are installed and a 2m long cable from the controller to the transceiver is included. Similarly, a power supply (12V / 0.8A) is included. The size of the antenna is 82 x 105 x 22cm and a weight of 12kg. The four loops each have a diameter of 80cm.
