50 Ohm Wire Antenna

Tinned copper bare copper clad steel polyethylene pe jacket material.

50 ohm wire antenna. Rg 58 19 stranded 20 conductor non contaminated jacket 50 ohm. The end wire size can range from 16 awg to 12 awg. Polyvinylchloride pvc 50 ohm. Place a 1 1 balun on the antenna end of the feedline.

But for a receiver it is normally sufficient to just connect the long wire to the input of the rf amp. The balun matches the balanced antenna into the unbalanced coax cable. Each pôle length is lambda 4 143 2f length of each radiator element in meter.

The antenna is constructed from a single length of 50 or 75 ohm coax with a coaxial feed point in the center.

To match that to 50 ohms would require a wide range antenna tuner. Lots of on line calculators for determining wavelength for a given frequency. The larger the wire the wider the bandwidth. As long as the rf amp is stable with the random source impedance it usually works well enought not.

No a simple wire that is 1 4 wavelength long will be very close to 50 ohms especially if vertical with respect to ground which can be the board s ground plane. 50 ohm 175 ft 1 2 antenna rope 600 ft 3 16 antenna rope 80 ft 5 16 antenna rope 300 ft our price. 300 ohm twin lead with the ends shorted is an option for even greater bandwidth. Pvc pipe is about lambda 4 long from the reflector.

One calculator is here. Sounds like you have an end fed random length wire as the antenna. For example 430mhz takes 16 6cm quarter wave length. The larger the wire the wider the bandwidth.

The antenna is designed to be fed with 50 or 75 ohm coax cable of most any length with a balun.
