Open wire line
I have 1000 feet of open wire line. It is made from 4 AWG stranded aluminum XHHW wire spaced on 5 inch centers. It is supported every 50 feet by 5 foot poles and there are 3 insulators between each support. Zo = 450 ohms +/- 5%. The loss is .3 dB on 160 meters including the transformers at each end

Long Wire Dipolantenne
This is a horizontal half-wave antenna that can be made of ordinary copper cable. The cable should have a cross section of 1 mm2 or more
Longwire with balun 9.1
Vi occorre un antenna semplice e di sicuro funzionamento, in pochi minuti potrete costruirvi una Long Wire di lunghezza casuale
Magnetic Longwire Balun
Le connessioni da fare: rosso della spira iniziale con nero della spira terminale. Il filo rosso va collegato all'antenna, il filo nero è la massa comune, i due fili collegati insieme vanno al centrale del cavo coassiale
Matched long-wire antenna
HF antennas, especially for lower bands, have large sizes and have to be mounted on a big height
