Liberty Net: July 30, 2016

IT’S LIGHTNING season. There are many methods of protecting your station from nearby strikes (nothing can protect it from a direct hit). One method used here at WB4AIO is this: I use open wire feedline. Where it enters my home, the two balanced-feedline wires pass through the wall by going through through two narrow plastic tubes just a little bit wider than the wires themselves.

Just about an inch or so outside the wall, each wire of the feedline is connected via a Powerpole quick-disconnect connector. When a storm is approaching, I just walk out to the back of the house, disconnect the feedline, and toss it ten or 15 feet away from the house. (This is also done when mowing the lawn, so the feedline is out of the way and out of danger.)

There’s no better way of keeping a lightning-induced spike on the antenna from entering my equipment than by having that antenna’s feedline a dozen feet from the house!

Another thing I do is keep a 2-Watt 22 Megohm high voltage resistor connected across the open wire feedline at all times. This absorbs practically no desired RF, but effectively prevents DC static charges from building up across the antenna’s feed system during precipitation or storms. Such DC buildup can sometimes cause loud popping sounds in your receiver called “precipitation static” — or even cause arcing when a passing storm front brings a large atmospheric voltage gradient along with it. With the resistor paralleling the feedline, any such charge is bled off before it can cause any problems.

Here are a few selections from the topics brought out on this week’s net, along with my comments:

• The murders, rapes, and other crimes committed by non-White invaders being brought into Germany by traitorous politicians like Angela Merkel are getting so overwhelming that Germans are starting to call this 2016 season “Merkel’s Summer of Slaughter.” (21 minutes)

SOMETHING to consider during this lightning season is having the capability to disconnect your antenna when local strikes are occurring. At WB4AIO, I use a couple of 30-amp Powerpole connectors to attach the open wire feedline for my antenna to the open wire feedthrough tubes that go through the outside wall of my house.

When a storm gets close, I just walk out to the back yard, disconnect the feedline by pulling apart the connectors, and throw it back toward the woods patch about ten or fifteen feet away. Problem solved!

I also have high-value (about 20 megohms) resistors permanently connected across the feeders so that local precipitation or atmospheric fronts are incapable of causing a static DC buildup on the line.

Here are a few items heard on the Liberty Net this week along with my commentary:

• The sudden collapse of the Kasich and Cruz campaigns could be just exactly what it seems to be — but it also might be an indication that the oligarchs have found another and more effective way of containing and controlling Trump, who just hired a Jewish hedge fund CEO and former Goldman Sachs operative as his finance chief. (29 minutes)

• Yet another Confederate monument is being removed by the forces of Political Correctness, this time at the University of Louisville in Kentucky. When White genes are replaced by non-White genes, all of our heritage will ultimately be lost; that is how civilizations fall. (32 minutes)

THE SUMMER THUNDERSTORM season has made me do some reading and reasoning on the topic of protecting your amateur radio equipment from lightning.
