Скачать или смотреть Ladder Line with Folded Dipole 40m Antenna Mounted

Ten meter long ladder line was made using 2.5 sq mm insulated copper wire, 2 inch long pieces of drip irrigation tubes with 6 mm diameter and 20 cm long black nylon ties. I was told that black nylon ties are resistant to solar ultraviolet rays while white ones are not. Drip irrigation tubes are also UV protected, but the insulated copper wire meant for home wiring may not be! I bought 60 m of 2.5 sq mm insulated copper wire, of which 20 m was used for the ladder line. Remaining part was mounted as a folded dipole antenna with a compromised mounting as there are no regular high locations for mounting here. There is no soldering or joints at the feedpoint as the ladder line continues as the folded dipole antenna. Read More: https://johnsonfrancis.org/techworld/...
