3 Element Tri-Band Yagi goes up.


Travelled down to Cris`s (VK2BOZ) place over the weekend to help with the installation of his Wilson 3 element Tri-Band Yagi antenna for 20,15 & 10 meters on his new 60 foot Hills 3 stage tower. We were planning to install a Cushcraft  3 element 4 band Yagi belonging to a friend of his, but several components were missing after being in storage for several years, so he decided to erect his old Yagi. Started to organize some gear on Saturday afternoon, picked up the mounting plate for the rotater and gave it several coats of paint and got all the cabling together.

Early start on Sunday morning with the rotator being bolted onto the plate and a length of pipe to mount the Yagi to. Cris was then up the ladder to install it , along with the RG-213 coax feedline from the Amritron RCS- 10/12 Antenna relay box. LMR 400 coax then runs from the relay box into the shack.


All was ready for the Yagi to be installed, Cris moved it closer to the tower and I climbed up to give him a hand. After several minutes of positioning the antenna through the 80 & 40 meter Inverted Vee`s and guy wires, the Yagi dropped into place. All bolts and nuts were checked and the rotator control wires installed. Final checks were made and the tower was taken up to the first level.

Unfortunately the rotator control cable came up short, so the tower had to stay at 40 feet. Not a big problem, a section of cable will be added to it in the next few days.

All was set, Cris headed into the shack and powered up the ICOM IC-7600, and after checking the SWR, all was found to be good. Pointing the antenna north into Asia and Eastern Russia, the signals were coming in loud and clear.

Cris rotated the Yagi south, long path into Europe over the poles, found a station in Poland calling CQ on 20 meters and answered back. Only operating on 100 watts, a signal report of 59+10db was received, and a 58 given in return. A few final adjustments are needed before the 400 watt Ameritron ALS-600 amplifier can be used.


Several more European stations were worked before trying out 15 & 10 meters, with good signal reports. It had been several years since Cris had been able to work 20,15 & 10 meters from home after his old tower was damaged and had to be replaced. No doubt it will be hard to get him out of the shack over the next few weeks. Won`t be long and the tower will be up to it`s full 60 feet. Great to see him back on air again.


The new tower and Yagi at 40 feet, still 20 feet to go.
