In reception, I only lost one point on average compared to dipole despite the poor release of the isotron

Si tratta di due dischi di alluminio, ma possono essere anche di altro materiale

Realization of the antenna, a gray pvc tube 32 mm in diameter and 1 meter long is required, the inductor will be made with sheathed electric wire of 2.5 mm square

A 32mm diameter gray PVC tube, 2mm copper-coated sheathed single-conductor wire 3mm with the sheath, two pvc sleeves for 32mm tube, two metal disks hs hard disks for example 13cm diameter

Wisotronker believed that the magnetic antenna had already been greatly miniaturized, and that the isotron found a further increase

There may be some environments where the dreaded antenna policy is so strict that you not dare put any short-wave antenna of usual dimensions outside

Nico has experienced that this antenna system works better indoors than a magnetic loop antenna

Experiments with isotron antenna for the 80, 40, 30, 20, 17, 15, 12 and 10 meter

Isotron 21 MHz antenna design enhancements

Resonates around 520 KHz,i tried with 15 watts and reached about 80km with s7

I have this Isotron purchased some time ago to use on 20 meter psk31 but never got around to it. In fact, the first time I played around with it the tuning did not make sense

Solve virtually any restricted space problem 40 meter isotron only 22 inches x 16 inches x 15 inches
