The metal part just came back from the galvanizing workshop

Non-metal parts before painting. These made of 7/14 mm thick PC board, removed Cu foil

A very easy way how to make current baluns at home within minutes


Tube parts on the ground. 10 m long, 90 mm OD Aluminium pipe (boom) and the elements

Weight test. The same boom guyed, loading its ends with high power audio amplifiers (about 20 kg each). No sag at all!

The central mast-to-boom plate with 1,5 m vertical steel support tube


I check the inductance of the calculated temporary loading coil. Just for test! The final solution will be made on high quality teflon

You can read the display of MFJ-259. The resonance and impedance is very close to the computer modelled value

The first resonance measurement. Now the antenna is just on half-way and hold on two points


Side view. You can see the thin plastic disc, that holds the whole coil tight on the Aluminium tube

The four coils. Enameled Cu wire is 3,4 mm and I wounded it to the 95 mm diameter teflon tube. The Q is very high - almost 800!

Installing the coils to the Al elements, inserting through fiberglass rods



Boom to element connection

The last check before lifting up the antenna. The staff: HA8XI, HA8LGA, HA8JV, HA8FM, HA8RX

Wow! The Yagi left the earth without any problem. All the elements are straight

Halfway to the top of tower. HA8FM is climbing on ladder, his help is needed at the basket


Bibo and Boti provide the balance of Yagi

We succesfully fixed the boom to mast (21. Apr. 2011. around Sunset). No waste of time - the first DX is 30 minute later in the LOG :)

The 2 el. 80m Yagi antenna next day. I like its shape!
