The Gary King (W4WKZ) Antenna Project


On December 5th, 2009 members of the West Tennessee Amateur Radio Society completed a community service project to assist a fellow Ham, disabled by blindness, repair his aging tower and replace the damagaed antenna array with new equipment.

Gary King (W4WKZ) has been a long-time Ham Radio operator in the Medon, Tennessee area.  The past few year's storms had severly damaged his antenna array which consisted of double 11 element two-meter beams and a Mosely, Jr. three element beam.  The tower was in poor repair, with the base of the Rohm 25 rusted off at the ground.  As it was, his station was unusable.

The frist step of the project was to secure the base of the tower and guide-wires so the old array could be removed.  You can see from the photo what sad shape is was in. 

To the secure the base of the tower, without having to drop it and start from scratch by digging a new foundation and re-assembling the structure, it was decided to pour a concrete base over the exisitng footing and brace the tower using 2-inch pipe as shown.  Now picture a bunch of middle-aged Hams in the heat of summer (90's +), cardiac prospects all, mixing and pouring a base approx one foot thick in a 6' X 6' x 6' triangle.  By the way, the mixing and pouring (11 bags 80 lb bags of concrete) was done with a 5 gallon bucket, a hoe, and garden hose.  A sight to behold, indeed!

After the base dried and cured, an inspection of the tower was made and it was determined, that although much more stable than before, was still in questionalbe shaple to climb.  Therefore plans were made to secure a bucket truck to remove the old array and install the new antennas. 


Randy Rushing of  Rushing Crane of Jackson, Tennessee and Andy Russell - KJ4CLS, kindly donated the use of a extended boom bucket truck for all the aerial work.  We are very grateful for thier help for we could not have completed this project without them.

In order to reduce the possibility of ever having to go back up that tower, the two-meter beams were replace with a Diamond dual band vertical which will cover the area that Gary would like.  At a heght of about 60 feet, this was accomplised.

The HF tri-element (which was missing an element) was replaced with a multi-band di-pole wire antenna built by Randy Bennett (W4RFB).  This was attached via a pulley system to allow the lowering and raising of the the antenna, without climbing, for repair and tuning.  Gary does not have an antenna tuner.

At the end of the day, all was installed and the W4WKZ station was once again operational and is now providing hours of Ham Radio pleasure to and old Ham who missed the hobby and unable to repair the damage himself.

Thanks to all participants in this project.  This list is long and I am afraid that I would accidently leave someone out.  Nevertheless, I would like to say a special thanks to Phillip Julian - KG4NVN - who conceived, planned, largely funded, and brought this project to fruition, once again confiming the fact that Hams as some of the best people you will ever meet.
