- Small size, since the antenna is
housed inside the suitcase between the
inner liner and the plastic box of the
exterior.
- Stationary wave ratio better than 1.2
across the covered band.

also closing it will change your tuning

ntenna description
INAC, has a magnetic antenna for use in travel or places that require a quick and
convenient start-up.
The magnetic antennas have the same basic configuration, coil and capacitor. In this
case it is a double loop, which without closing the suitcase is an "8" figure and closed
the suitcase is a two-turn loop.
In our case, that is to say in the model MAK-721, we have created a model that
covers the central part of the band, from 7 to 21 Mhz, with the advantage being the
bands used for the local communication (40 meters) And the DX (20 meters).
The capacitor is handled directly on the shaft, with a maximum capacity rotation at a
minimum of 180 degrees. The setting can be made in reception at maximum noise or
in transmission at minimum level of standing waves.
The handling of the transmitting capacitor must be done with reduced power as it
can cause burns on the plates of the condenser.
