Tower #2 is now operational (8/20/00)!


The second tower is also Rohn 45.  There are 8 sections plus about 2 feet sticking out of the concrete base.  The tower was built on a concrete slab that used to be the floor of a barn behind the current garage.

Here are some shots of us getting things together...

The tower sections arrive after a trip to be re-galvanized. 

N9VA sets up the mast mounting hardware. There are two Rohn TB-3 thrust bearings used to hold the 170lb mast.  NI9E and KA9WXN are checking over the hardware. 

 

N9LLT and NI9E drive one of the 7 8' ground rods while N9VA and K9YNF supervise. 

Stacking the first few sections...

N9VA and I put up the first 50 feet as pretty much a  two-man operation.  This is yet another place where a 20hp garden tractor can come in handy!  You can see the concrete slab where the barn once stood.  Part of the original fieldstone wall is visible to the right.

Setting up the guy hardware. There is a set of guys at 35' and another set at 75'.   Anchors are 8' long galvanized rods with a 8" helix on the end and are rated for around 10K lbs pullout in undisturbed soil.  Guy material is 3/8" fiberglass rod from Polygon.  The ends are 1/4" EHS steel cable. 

Here's a shot facing south.  Tower 1 is on the left and tower 2 is on the right.  You can also see an R5 mounted to the silo - comes in handy once and a while.  Thanks to Ted, N9LLT for most of these pictures.

Here's a series of shots showing the 20m antenna going up the tramline.  
We were lucky to pick a day with winds less than 15MPH. 
View from the ground.  N9VA is on the tower. 
Up she goes.  All the pulling is done by the tractor.  One man on each tag line and one on the tip line to roll the elements around the guys 
Got it! 
The finished product.  Plays great for an antenna at 80 feet.
