Easy base radials for vertical antennas
WebThis is EXTREMELY easy to assemble, requires no tuning or adjustments and VSWR is under 1.6:1 continuously from 3.5MHz – 57MHz! It is not a 1/4 wave vertical, but an end-fed long wire type antenna with a matching … WebThis vertical requires a ground plane, and it's best if it angles down to bring the feed- Figure I—The sleek, low-profile whip antenna is hardly visible against the daylight sky. One radial wire can be seen sloping away from the bracket at roughly a 450 angle. point impedance close to 50 Q. I used three radials made of 8-foot pieces of scrap wire

WebA full wavelength at 3.8 MHz is 984/3.8 or 258.9 feet. Lets round that up to 260 feet. 260*.05 = 13 feet. Assuming that our radials are a quarter wavelength long then each radial is 65 feet long and the circumference of the circle covered by our radials is 2*pi*65 or 2*3.1416*65 or 408 feet.
WebThree or four radial monopole antennas are the most popular configuration. One interesting consequence of adding still more symmetrical radials to the base of a monopole antenna is raising the capacitance between the radials and monopole. The net effect of this is each radial can now be a bit shorter in length. how to take screenshot in thinkpad lenovoWebHigh Performance 40 Meters Vertical . Without Radials .
