Liberty Net: May 7, 2016

Inverted-L_antenna_with_counterpoiseby Kevin Strom, WB4AIO

SOMETIMES PEOPLE wonder about what kind of antennas are used by Liberty Net participants — and this is an excellent thing to know, since by emulating those with excellent signals, you are likely to have an excellent signal too.

W1WCR uses a 165′ long doublet fed in the center with open wire line, up about 90 feet in the air. There is an extensive ground screen underneath the antenna in every direction. N2IRJ uses a pyramid antenna, which is two inverted vees at right angles to each other fed by the same coaxial feedline — one tuned for the low end of 80 meters, the other for the high end of 75 meters — with the apex up about 50 feet. W3JMD uses a cage dipole up in the clear at 32 feet, with a somewhat longer wire ground reflector directly underneath it. WB4AIO uses an inverted L that goes up more or less vertically for about 80′ (the wire slants somewhat, so the highest point is about 65-70′), then almost horizontally for approximately 70′ for a total wire length of 150′. The antenna base feedpoint is seven feet above the ground and there are two elevated 50′ radials. The L is fed by open wire line with a current balun at each end.

Note that all of these antennas are full size (or larger) for the band in question, and do not use traps or coils of any kind in the antenna wires.

Here is my take on a small selection of the ideas put forth on the Liberty Net this session:

• Now that hyper-Zionist oligarch Sheldon Adelson, who has been the de facto owner of the Republican party for years, has endorsed Donald Trump, does that signal that a deal has been made between the establishment and “anti-establishment” Trump? (30 minutes)
