Di semplicissima esecuzione, non presenta alcun tipo di difficolta' per il suo montaggio
Active Ferrite Rod Antenna for HF
The red connector is for an optional external antenna wire and the black connector is for a ground wire. The red is wired to secondary winding and the black is connected to the circuit ground plan
Ascoltare i radiofari OL con una antenna filare accordata

A Low Cost Loop Antenna
One of the greatest problems encountered when one likes DXing on the lower frequencies such as 1.8 and 3.5/3.8 Mhz is weak signal reception
Noise Cancellation Project
The noise cancelling system to be described here consists of the Main Station Antenna receiving a wanted signal and associated QRM and a separate
