WebThe Sloper Antenna Explained. The classic sloper antenna is a top-fed 1/4 wave vertical antenna sloping down and away from a tower. The sloper's feed point is anchored high above ground near the top of the tower on … WebDec 22, 2024 · With an EFHW the antenna resonates on all harmonic bands with a good match, so using a 40 or 80m version and adding wire to resonate on 160m will in effect parallel two antennas operating on the same bands and pull the feedpoint impedance down, plus you will have RF currents flowing in different directions at the same time causing …
WebThe EFHW revamped... The idea was to set up an EFHW as inverted-L : from the feedpoint at the edge of property, about 10m upwards into the direction roof ridge, then bent in a 90° angle sloping downwards for 10m towards the garden house, so in total about 20m in length. http://vtenn.com/Blog/?p=1089

WebAug 12, 2016 · End-fed wire antennas are a different beast. They are not a half-wavelength long, meaning that, if you choose the length of the radiator wisely, the impedance at the end of the wire will not be as high as the impedance of a half wavelength long wire.
