escription of the antenna
INAC magnetic antenna has a tunable remote actuation and with a quick tuning of less
than one second from end to end of the band.
The magnetic antennas have the same basic configuration, coil and condenser.
AH-376
Obviously, to get a complete spectrum of the HF ham bands, ie 1.6 to 30 Mhz., Has to
have different skills and different coils. Determine the inductance coils, as a rule, we
can say that the greater the diameter of halo, higher inductance. Thus, for frequen-
cies of 1.6 to 4 MHz. The size of the coil for acceptable performance is 3.4 meters in
diameter and against higher frequencies, such as 14 to 30 MHz. Simply avoid reach one
meter in diameter.
In our case, ie in the Ah-376 model, we created a model that covers the center of the
band, from 3,0 to 7,8 Mhz., With the advantage that more bands are used between the
frequencies of 3,5 and 7 Mhz.
The condenser is operated remotely and commanding performance, is placed in the
radio room, and the feeling you get, it is as if we moved the axle directly control the
variable capacitor shaft. With the advantage of appreciating the naked ear the presence
of noise in the tuned band, indicating the input of the antenna tuned.
