http://www.vk6.org/160m_vertical_antenna/ WitrynaThe 160-meter loading coils ( Hy Power LC1682) are placed at the 70% point following the design by Hy Power for their 82-foot horizontal 160-meter antenna. Since each leg was originally 40 feet long, the loading coils were placed at the 28-foot position. The antenna was tuned for 1840 kHz to maximize FT8 digital mode operation.

WitrynaA 160 meter dipole. The dipole for 160 meters is just like the dipoles that we build for 40 or 20 meters. The difference being that they are BIG! With out any loading coils to possibly shorten the antenna, it will be nearly 260 feet long! Of course, this is larger than a typical city home lot, so the dipole may have limited application. WitrynaThe coil data will be listed for each band will be at the lowest frequency of that band, i.e., 1.8 MHz for 160 meters, 3.5 for 80, etc. The three base-loaded, and the continuously loaded antennas, will be computed as having 1 inch or 25.4 mm of coupling before the start of the coil. The coil diameters that will be used will vary from a seymour estate agents camberley

From left to right: ~5uH loading coil, 3x120pF, 100uH static bleed off coil. (the bleed off coil is not connected to the caps, the image is skewed) So to recap, if your resonance point is too high, your antenna is electrically too.
