wire antenna for a range of 1.9 MHz

Range of 1.9 MHz or 160 meters when it was very popular among novice hams former USSR. Today, apart from interference on it you will hear nothing . One of the problems of falling interest to a range of 1.9 MHz was of course the complexity of the antenna . To work effectively in this range, the length of the antenna wire should be 40 meters, depth of the antenna should be almost the same at a lower altitude aerial suspension ceases to work effectively in medium and long routes . The most effective range of the antennas to 1.9 MHz (160 meters) are the dipole and loop antenna , the length of which is commensurate to the wavelength. But to establish a dipole wire antenna type is also problematic , such an antenna length should be about 80 meters. In order to reduce the physical length of the antenna can be applied lengthening doghouse as in antenna w3dzz, the antenna can be used to work in a range of 1.9 MHz as shown in the figure below . Unlike in this embodiment w3dzz no capacitors and it can also perform as the " inverter V". The length of the wire antenna is reduced in two (in comparison with the dipole ) , to reduce the loss extending spools must have their own small losses and high Q (of order 150) are also protected from moisture. Connect the antenna 50 ohm coaxial cable , when the size of said inductance coils L1 and L2 should be 70 mH. Setting wire antenna produce change in the length of external conductors ( Figure they have a length of 14 meters) . Having measuring instruments MFJ or other firm I think setting this wire antenna will not cause difficulties . Antennas operate as " inverter V" on the mast height of 15 meters.
