WebI came across the following antenna which covers the 80-10m bands with no traps and just one loading coil. It is called the EFHW-8010. It is simply a half wave end-fed on 80m which will resonate on all multiples of that frequency, loaded with a small inductance near the feed end. This inductance has the effect of bring the resonances a bit ... WebThis antenna wire is fed via a section of parallel-wire transmission line with 1/4 the length of the antenna wire (i.e., 67 / 4 ≈ 17 ft). An 84 ft long end-fed antenna wire, with a "counterpoise" wire of 1/5 the length of that antenna wire (i.e., 84 / 5 ≈ 17 ft). how did criss angel walk up the luxor

WebWire Antenna Calculator. The following program will calculate the lengths needed to construct several popular wire antennas. All you need to do is enter the desired resonant (center) frequency in the form below, then click "Calculate". The correct lengths for the various models will be displayed in the chart. (To better understand the variables ... WebOn 20m band it's a half wave antenna. Highest current (radiation) in the middle of the wire. On 40m it's a quarter wave antenna (-3dB). On 80m it's a compromise antenna. To … WebThe theoretical impedance of a center fed dipole antenna far removed from ground effects is around 73Ω. As the feed point moves towards one end, the impedance gradually end shows an impedance of around 200Ω +/- 100Ω. Some commercially available antennas impedance point.
