One of the three crank up towers had a problem. The head unit witch falls into the top section of the tower has two places where it is bolted together. One of them broke. I temporary fixed it. Now I can tilt over the tower and repair is defiantly.
Mounted a temperary threaded rod to the tower.
The top of the threaded rod in the connection on the head unit. See the hole where was the prevuous connection.
Today Jan PA0VAJ and Thomas PA1M where here to help to lift the bottum 20m =yuagis in the south west tower. I mounted a tram line to the wower and a pully with a rope to bring the tower to the tower.
Antenna going up with help of the tram line and a pull line.
I started to build two 5 element Op-Des yagis from Innove antennas for the 20m stack.
The yagis have a boom off 9,4 meter.
Last year we put the SteppIR in the south west tower (tower7) to test it. I am satisfied with it and decided to put it up in the multiplier tower. (tower 6). So Thomas PA1M and Jan where here to help. We took it down and we made some arrangements to lift it to the new tower.
The first attempt was not a success because the dipole was not in balance as it has a special boom so that is do not have to lift the banana dipole over the tower.
The top of mast pipe is 3 meter oboe the normal sections off the tower. The mast pipe I can lower tow meters so I can put a yagi in and then lift the pipe to it position again. I do not want to climb on top of the tower. To lift the antenna as high as possible a college welded an attachment witch I can put over the mast pipe. At the attachment I connect a tramline and an extra wire to secure the opposite side of the tower. Also there is a pulley where the rope is connected that pulls the antenna to the tower. Today we first installed the attachment. and made preparations to lift the SteppIR dipole.
Left the pulley to pull the antenna up. On the arms we connect the tramline. The wooden pole is used to put it over the mast pipe. This one is a bit short.
