I finally made the decision to put up another Ham Radio Tower. It's has been since 1986 I have had a radio tower in the backyard and the choice was made on a telescoping tilt-over by U.S. Tower model MA-40. I no longer at this age have any desire to climb an antenna tower. This is the reason for the tilt over. I just crank it down across the backyard and then I can make adjustments to the antennas or rotator. Due to Hurricane Katrina and Rita, I had to wait
about 3 months after I paid for the radio tower to have the tower delivered. Which was alright because we had
to get engineering, building permits, dig the hole, set the steel, pour the
concrete then allow the concrete to set and cure for 28 days. U.S. Tower did
send me the anchor bolts ahead of time along with a template so when the
tower did arrive all I had to do was bolt it down and crank it up.
The Engineer required us to drill a pier 12" diameter x 10' deep.
The
city didn't accept U.S. Tower's engineered plans for 2 reasons. First the
Engineer was licensed in California not Texas and second, the seal on
those plans had an expired date on the engineer's seal. No problem. $200.00 paid
for a local engineer to come up with the footing plans with a good Texas
Professional Engineer's Seal that the city would accept.
On our way to
the 10' depth we hit rock at 6'-6" and continued for another foot to 7'-6". The
Engineer accepted that as good enough. Thank goodness for my
sons who were a great help in the heavy work. The box is 36"x36"x30" then the pier continues to 7'-6" below
the surface and 12" of that is into limestone rock. Renting the Bobcat was a little expensive but we believe we're
not going to have a tower leaning after a few years. All this expense and
work so I can talk to people I don't know, my wife asked.
The amateur radio tower is 40' high at it's full extension. The beam is a Force-12 C3SS fed with about 80 feet of LMR-400 coax. Right below the rotator I have a 80 meter / 30 meter dipole.
