Allways a good idea to recondition legs when reusing sections. Jan 1 2009
|
|
|
|
I figured a 10"x 42" hole of concrete and rebar would hold better then just the anchor blade alone, leaving about 8" of the 48" anchor exposed.
|
|
|
|
Why is the phone line here? Looks like they had to go around the patio.
|
|
|
|
Kindorf channel and first two sections as the concrete cures with the ginpole ready to go.
|
|
|
|
The first 50 feet strait up!!!
|
|
|
|
|
|
Ginpole ready to move up and lift the next section to 60 feet.

Made it to 80 feet with no snags. Jan 30 2009

|
The plumb bob gets tricky at this hight. I ended up making final ajustments after midnight.
|
|
|
|
I welded a tab plate to the anchors to simplify turnbuckle attachment. South shown.
|
|
|
|
|
|
On the east side the safty cables can be seen locking the turnbuckels in position.
|
|
|
|
The west side is a different story. I fabbed this mount out of 3/16 and used about 5 coats of cold galvanizing compound.
|
|
|
|
I thought the best way to take the load off the roof was to distibute it to the foundation.

|
The tower and it's antennas
|
|
|
|
First cable run of control, ethernet, and power cables.
|
|
|
|
The first few antennas are up at this point with the ground system started. Feb 16 2009
|
|
|
|
I think theres room for more coax. Mar 15 2010
|
|
|
|
Working the LDF4 run to the new Sinclair folded dipole.
|
|
|
|
There are 8 total grounding rods in this system tied together with 1 inch copper strap.
|
|
|
|
|
|
This what I used to temporarily keep the water out of a unused LDF4 run.
|
|
|
|
Andrew Vapor Wrap and Super33 is used on all outdoor coax connections.
|
|
|
|
The lower is a RX only for EMS fire and the UP railroad that streams to the web at 70'. The upper is for the APRS digi and I gate at 83'.
|
|
|
|
This is one of the WiFi sector antennas with the 900Mhz Data-Link antenna for the remote weather station at 80'.
|
|
|
|
This is the double cross APT sattelite receive antanna.

Left the VHF RX, right UHF RX, with the tower cam in the middle at 99'.

Installing the lower standoff bracket. Thanks for the help James W7SNK right
|
|
|
|
The Sinclair folded dipole, the divorced transmit antenna for the 145.500 repeater.
|
|
|
|
These antenna arn't for the light at heart. They are long and awkward at 20 feet.
|
|
|
|
Attching the folded dipole to the upper bracket.
|
|
|
|
Now the lower.
|
|
|
|
|
|
Connecting the LDF4 to the antenna harness and waiting to seal conections untill testing is compleat.
|
|
|
|
My 130' HF doublet can be seen on the right 80 feet up.
|
|
|
|
Securing the new cable run on the way down. 8 coax runs are hardline ranging from 3/8" to 7/8"
|
|
|
|
Almost done. Let's hope it preforms as well as it looks!
|

Repeater UHF and VHF RX Wacom cans and VHF ARR2 preamp. All cabling in this system is hardline with some short peices double shielded variety.

Some photos of the old short tower. 2000-2008
|
|
|
|
This how the tower looked for many years at 38 feet. It also had a 6M meter yagi and a homebrew 10M Moxon just after this photo in 2007.
|
|
|
|
This was the UHF receiver, filter, and pre-amp for the old crossband 145.500 repeater. 2006
