It&#8217;s a classic inverted L, it&#8217;s only 9 meters high and it has an 11 meter long single wire hat.<\/div>\n<div style=\"text-align: justify;\">The position is really not elevated, the base is about only 2 meters from my terrace.<\/div>\n<div style=\"text-align: justify;\">To get better performances I&#8217;ve put the loads the higher that was possible.<\/div>\n<div style=\"text-align: justify;\">Starting from the base, where there is the variometer, the wire of antenna goes up for about 5 meters, then came back down for other 2,5 meters, then goes up again rolling up around the main fishing pole. At this point there is a 15 cm 3 layers coil, not so good for getting best performance, but&#8230;<\/div>\n<div style=\"text-align: justify;\">The wire continues toward the tip of the rod where it&#8217;ll become the horizontal hat for other 11 meters about.    I&#8217;ve only one random radial, 15 meter long about, and a connection to the ground.<\/div>\n<div style=\"text-align: justify;\">This ground connection gives me a lot of noise making reception almost impossible. Without this ground connection the antenna is a very quiet antenna for receiving, too.<\/div>\n<div style=\"text-align: justify;\">Transmission power without grounding worsens drastically.<\/div>\n<div style=\"text-align: justify;\">The variometer is remote controlled by a stepper, but about this I&#8217;ll speak later.
