Web15 de out. de 2024 · Using Google Maps to measure the distance between the tree and the house for my End Fed Half Wave antenna. So I started to look into End Fed Half Wave … WebThe key advantage of an end fed half wave is the single high support point with accessible feed and current maximum some distance away from the feed point. If you don't need the feed point to be nearby, consider an inverted V -- avoid the loss in the matching network. The current maximum will be close to the center of basically any half wave ...

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). WebOne such antenna is the W3EDP end fed. It consists of an 85ft wire fed against a 17ft counterpoise (attached to the earth point on the ATU). Some books say that you don’t …
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 ... 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 ...
WebIn reported traditional antennas, slot antennas [12,13,14,15] were the main choices to match the impedance of JJ, such as double-slot antenna and ring-slot antenna [17,18]. However, these kinds of antennas have to be fed by coplanar waveguide (CPW), meaning the shape of the ground has to be changed during the impedance matching.
