What makes copper a good choice for an antenna?
One thing that makes copper an outstanding choice for antennas is that it is a very efficient conductor of electrical energy. In fact about the only common element that is more conductive than copper is silver.
Which is the best conductor for a dipole antenna?
This wire is the best conductor and is multistrand and is made up of tinned copper which is a good conductor so often. The conductor comes with a diameter of 1.1 mm or 0.433 inches, the outer jack has a diameter of 1.5mm or 0.06 inches. The wire has an RF power of a maximum of 500 watts SSB 300 watts CW/DATA.
How big is a wire for a dipole antenna?
The amount of current a wire can carry is proportional to its size keeping track of this fact the wire has a diameter of around 0.0641 inches and comes with a length of 80 feet. The product weighs around 1 pound. The wire is usually composed of copper but for giving it ductile properties the wire is annealed.
What is the best material for an antenna?
Copper is a best suited material for base antennas. The metal, while soft and malleable, is quite rigid. Stainless steel has a higher tensile strength, so thinner wire can be used. This makes steel an excellent choice for mobile whip antennas where flexibility is a must.
Why are antennas made out of copper or silver?
One thing that makes copper an outstanding choice for antennas is that it is a very efficient conductor of electrical energy. In fact about the only common element that is more conductive than copper is silver. You can imagine what an antenna built out of silver would cost.
Where are the Blue wires on a balun HF antenna?
Connect the primary side of the ring core (bottom, where the blue wires are next to each other) to the coax connector. The two blue wires at the center core of the coax connector and the black wires on the chassis part with a cable lug. Remove the plastic parts from the cable lug so that a solid solder connection can be made.
What kind of wire does a firestik antenna use?
The “FS” antennas are 100% American made with 100% American materials. To maintain a balance between flexibility and ruggedness, we use a custom blended, glass fiber reinforced shaft. Each is wound with heavy insulated copper wire to prevent the oxidation and shorted windings often found on non-Firestik antennas.
What kind of antenna do I need for Cobra 75?
Setup: A Cobra 75 all in one radio, auxiliary speaker, and 18′ of firestik ring-connector coaxial cable, and 3′ Firestik antenna. SWR Tuning: After educating myself I bought a used SWR meter and saw 1.6-1.7 prior to making any adjustments.
