End Fed Antenna Length Chart

End Fed Antenna Length Chart - Web formula the efhw antenna calculator uses the following formula to calculate the antenna length: Some say any length will work, some stress odd multiples of 1/4 wavelength, while others lean toward even multiples of 1/2 wavelengths. Longer wire is always more efficient but is usually best kept under 300 feet in overall length. 186 ft / 16.5 ft and 186 ft / 33 ft. 450 ohm average antenna impedance to 50 ohm coax, also know as a 9:1 unun). Length (feet) = 468 / frequency (mhz) where: Web the single wire end fed antenna is probably the simplest antenna to use. Frequency (mhz) is the desired operating frequency in megahertz. The antenna tuner will load an end fed long wire effectively, especially if it is cut to aprox. Length (feet) is the optimal antenna length.

( You May Want To Make A Note Of Them) Revised:

The impedance varies over a very wide range, depending on the length in wavelengths. It requires some sort of ground connection to work. Web the single wire end fed antenna is probably the simplest antenna to use. Length (feet) is the optimal antenna length.

The Entire Antenna Is #12 Stranded Insulated Copper.

Length (feet) = 468 / frequency (mhz) where: The antenna tuner will load an end fed long wire effectively, especially if it is cut to aprox. Frequency (mhz) is the desired operating frequency in megahertz. 186 ft / 16.5 ft and 186 ft / 33 ft.

Above 300 feet the characteristics of a beverage antenna begin to show up. 29 35.5 41 58 71 84 107 119 148 203 347 407 423. Some say any length will work, some stress odd multiples of 1/4 wavelength, while others lean toward even multiples of 1/2 wavelengths. But when you start looking around, you find that no one can agree on what length to use.

Web Formula The Efhw Antenna Calculator Uses The Following Formula To Calculate The Antenna Length:

Longer wire is always more efficient but is usually best kept under 300 feet in overall length. 450 ohm average antenna impedance to 50 ohm coax, also know as a 9:1 unun). Example let’s say you want to design an efhw antenna for a frequency of 14.2 mhz.
