160 Foot Tower Project to 190 Foot Tower Project <<<here>>>
Also An affordable, yet sturdy Vertical Fall Arrest (home-brew) System.
Picture of my little 160 ft. 45G tower, exclusively guyed with .3 inch OD
phillystran/aramid. The two upper guys are terminated with Torque arm
stabilizers from Norm's Fab in Michigan. The last 30 feet and beams checked and
installed by Matt, KC1XX of
http://www.xxtowers.com/
I use strand vises to terminate and tension the 1/4 inch galvanized ground
porcupine leaders. Some of the leaders are 40 feet long as I enjoy small trees
near the 12 foot 10 inch guying screw augers.
The first 50 feet of tower was straightened and checked with a carpenters level.
The remaining guys were tensioned by feel/insight and tower sighted up from its
three sides for straight. One of my guy points is much higher than the tower
base and closer. I put up the first 140 feet
myself with one ground helper. On top is the little Comet 6, 2 & 70Cm Vertical hooked to a FT-8900R through
200 feet of LMR600.
Next down is the 6 meter Force 12 5 element beam for my
Lafayette HA-460 through LMR600 .
Then a space for the two 2 meter 7 element vertically stacked beams being
assembled soon & 70 Cm.
On the bottom above the Yaesu thrust bearing (laterally supporting 11 feet of
61T6 2 inch OD, 1/4 in. wall pipe) is a small trap-less Force 12 C3S/HH 140 mph
survival, 6 element, 1 reflector/1driven element on each band.
Short 12 foot boom for 20, 15 & 10 awaiting the next ice storm test!

Feed lines are 1000 feet of LMR400 and 500 feet of LMR600 available UPS from
Maryland on e-bay.
Before Winter I will add a 80 meter bi-square quad towards New Mexico which will
be feed at the 153 foot level (upper inverted V supported by existing philly
guys) At the bottom will be a vaccccummm relay to short the bottom V section,
affording an 160 meter loop feed at the top. Regards John, Southern Vermont
Top Section being installed by Phillip with Ham M 4 Rotor and Comet tri-bander
