Radials first the Home QTH part 2

Of course the day started cold, right around freezing with a light frost on the ground.  A bit colder than usual for mid-May around here.

32F/0c – cold for May 12th around here


The white frost still shows in the shade. Temperatures did get up to 53F/12c for a glorious half-hour. – Notice the old tow-behind cutter.

First job was to move the old tow-behind cutter that is a lawn decoration.  Had to be pried from the ground and dragged out of the hole where it had settled into.  The tractor’s hear lift did the jacking and the ATV dragged it away.

Next stakes went in to provide guidance for both the pattern and for the radial lengths.  I put in 12 stakes at 30-degrees from each other. I made up a rope harness that with a layout line worked out to the length for each radial.  As radial fields are not precision work the angles were spot checked as were the lengths.

Here is the result:

They are all in. We’re raking and leveling.

Radials for the home QTH Flag Pole Vertical

Installing vertical antenna radials is a chore.  Period.

In my Zero-Five Flagpole Vertical Antenna the designer suggestion is radials nominally the same length as the pole with at least 30 radials if possible.

Vertical with 30 radials (taken from a text book)

They also note that at that point more radials do not seem effective or worth the efforts & costs, with little improvement even if you double the number of radials.

So I’ve settled on installing 36 radials, which makes them an easy 10 degree spacing, with a nominal length of 32 feet each.  This will put down roughly 1152 lineal feet of radials of which 6 radials or 192 lineal feet are extras above the suggestion.

K9ZW Shacks Evolve – Proper Dummy Loads, Additional Metering, New Power Distribution, Specialized Headsets and more…

I knew that doing a new station build wasn’t for the faint of heart, and as usual I am loath to miss a chance for upgrading the home QTH station.

All in all the order and assemble is fun other than the bills.  Now in spring the read work begins!
