http://www.laud.no/la6nca/loop/index.htmloop no. 2 was a car mount loop.
size: 160 cm x 120 cm.
frequency range: 3.5 to 7.5 mhz.
two loops of 1x10mm cu was used.
the capacitor is mounted on the top of the loop, and is actuated by a motor.
test results are very good.
for communications from 20 to 200 km is this small loop better or as good as a full size field mounted dipole.
an hf whip antenna is also mounted on the car.
the magnetic loop is fare better than the whip antenna.
