Tower Guy Wires...

 My son, Chris, and I installed my tower back in 1993. In 1998, I had to move the northeast guy cables to provide clearance for a shop addition, so I installed an elevated guy point. When I put the backup anchor in, there was no tree here. 32 years later, you can barely see the turn buckle exposed from the tree that swallowed it! Additionally, after the big rains recently, a spare guy plate arose from the ground, where it had disappeared in 1998. :-)

Taking a Tower Down...

 Earlier in the year, I helped a friend, K4WGD,  remove a tower from a location that will ultimately be reinstalled at his QTH. I finally got around to editing a zillion photos down to the basics. I'm the guy on the tower in these pics. It was a 110' commercial Motorola tower, very similar to a Rohn tower in design. There were several antennas, feed line, guy cables, anchors, turnbuckles, etc that all had to be removed. We also discovered the based had failed at some point in time, and it became very unstable below the lowest guy cables and temporary support had to be installed during the disassembly. My buddy was the ground crew, he ran the tractor, tied and untied parts, etc. Due to early summer storms popping up almost every day, it took the better part of the week to get it disassembled and clean up the site. These photos aren't in exact order, but you'll get the idea.

More of the yagi's back up on the tower...

It was a long, tiring day, but what a great feeling to look up and see it all beginning to come back together. It's been over 2 years since the storm took my antennas and tower down. Today we got more antenna work finished, and it's much closer to being completed. 
 

The 5 element yagi for 6 meters and 13 element yagi for 2 meters SSB (horizontal) are now installed at 108' and 111' respectively, feedlines installed & terminated, and other tower maintenance done. Still have to install stuff for 2m / 220 / 440 FM, and raise the 160, 80, & 40 meter antennas from 65' to abt 100', and 30 meters to about 90'.

 The 13 element 2M SSB yagi propped up against the house, waiting to be pulled up the tower.

 Looking to the NW at about 80'. You can see the top guy wire coming down from above in the photo.
 
 The view as I was climbing up the tower. The work / tool bucket was already tied to the tower near the top...

  Looking down from the rotator shelf at about 100', at the 2m SSB yagi to be installed with horizontal polarization at about 111' on the tower.

 Looking up at the mast where the yagi's will be installed...

 Looking to the west from under the 2M SSB yagi at about 111'.

 Looking up through the HF, 6m, and 2m yagis while on the tower.

 Looking to the west at about 105', just below the Force-12 HF Yagi...

 View to the east at about 105', under the Force 12 HF yagi


 
 Looking straight up the tower at the yagi stack. More antennas coming to fill that space :-)

 An opening in the trees frames the view of the new yagi stack from the back yard.

 Looking up at the tower and yagi stack from the rear deck.. More tower work coming soon!

Tower Work, 9/27/17

I had time to climb the tower and do a bit more work before dark. I got the rotor mast installed, set the height of the mast so as to not vertically load the rotator, locked the thrust bearing inner race to the mast, slipped a home brew rain/ice skirt in place over the thrust bearing, and the pulled the rope back down the tower for the next task.

 Rotator mast installed into the tower top, working on the ice/rain shield. I didn't have this for the first 23 years of use, and it would get water in the top of the bearing and freeze up every year...


 Top thrust bearing now has a shield to help keep ice and rain out...


Looking down the torque arm on the top NE guy wire.


A better view of the torque arrestor in use on the top guy wires.


 Rotator locked to the mast and ready to get busy!


 Looking up the tower to the mast that will soon be supporting the rotatable antenna array.


The sun was setting on me again, while I was up the tower... time to climb down!
