FAQ:

Q: What is the best wire for an antenna?

A: The best wire to use in making a long wire antenna is a hard drawn copper or copper clad wire of around 12 or 14 gauge. These two wires will produce minimum stretch over long periods.

Q: What is the length of a 40 Meter Dipole?

A: A 40 meter dipole is around 10.10 meters per side. As the fishing poles I had lying around were 8.70 meters this is what I used. Most of the mechanical construction is now ready. Wire length and support. The length of the fishing rods is 8.70 meters and yes, too short.

Q: How do you calculate dipole antenna?

A: The formula to calculate the length of the antenna is 147/frequency in MHz, this gives the total length of the dipole in metres. For example, to make a 150MHz dipole: 147/150 = 98cm so each element of the dipole should be 49cm.

Q: What is a wire antenna?

A: A random wire antenna is a radio antenna consisting of a long wire suspended above the ground, whose length does not bear a relation to the wavelength of the radio waves used, but is typically chosen more for convenience. The wire may be straight or it may be strung back and forth between trees or walls just…
