Satellite Tower Installation
Below are links to photos of the satellite tower construction.
- 2 10ft 1.5in square tube joined with angle iron. Overall mast height 20ft.
- 2 rotator platforms. The bottom platform will hold a Ham-IV
rotator and the top platform has 2in hole co-axial of the rotator below.
Through the hole will be attached a 14ft 1.75in O.D. Alumunum mast
of respective wall-thickness and alloy for strength and weight
advantages (stronger and lighter).
- Attached to mast will be other UHF and higher frequency antennas
dedicated to local terrestrial use.
- The plan is to install the Yaesu G-550 at the top of the 14ft
mast and then place 2m, 70cm and 1.2Ghz antennas controlled by Elevation
rotator (G-550), and Azimuth rotator (Ham-IV).
- Total length from feed point to radio is approx 50ft electrically.

Notes: The 3ft section of 1.5in square tube is doubled up with another
inside the shack bolted through and sandwiched around the frame of the
shack. The top mount is further lag-bolted vertically through the
top-plate of the shack frame. The mast isn't going anywhere. ;-)

Notes: The flood light mast is going to be removed prior to
installing antennas, so there will be ample (10ft) of gap between the
apex of the roof of the shack and the Elevation boom (horizontal)
attached to the Azimuth boom (vertical).
- Steel is used in the mast, platform and supports.
- 5/16in stainless hardware is used throughout for attaching the mast
and it's parts.
- The mast is installed on a hinge at the bottom that allows the whole
structure to be lowered and serviced for safety and convenience.
