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

Open Wire Feeder Construction
For the suppliers of 450 ohm open feeder. It is far easier to build this than find suppliers of this cable, and its a great deal less expensive

Rhombic antenna project
Back in the 1980's I built this Rhombic Antenna on an Island owned by Movie Actor Marlon Brando. He was a Amateur Radio Operator and wanted an antenna that would help him communicate better with his home in Los Angeles, California.

The inverted V-shaped dipole
The simplicity of the inverted V-shaped dipole it consists of a half-wave dipole

50 MHz preamp Gain 26dB with the BFG135

50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
