I recently have moved to a new home, SW of Atlanta and have a SteppIR
3-element with the 30/40 add on sitting in the garage waiting on a new
tower.
I have approval from the HOA and County to erect a Tower, home deed was
filed with modifications to allow a ham radio tower and antennas.
Although no specific restrictions on height or style are place on me by
the HOA or the deed modifications, when I started the process
I thought a US Tower MARB-550 would look very neighbor friendly and be
easy to get buy in's by all.
I already have a base for the tower in-place but I am a little concerned
as to the ratings for the MARB when comparing a TX-455 style.
My Counties wind rating is 70MPH, we have already seen 50MPH gusts
during a thunderstorm recently.
The tower is rated at 9 sq/ft at 70 MPH and 61#'s weight, the specified
wind load by SteppIR is 8.1 sq/ft. at 58#'s I would elect to use the
rotating n base thus keeping the rotor at the bottom of the tower and
reducing the extra weight and little load.
Now the questions?
1. Since I am almost right on top of the spec's, wind load and weight,
should I abandon this Tower selection.
a. As it now stands I have a 3'-6" x 3'- 6" x 6" concrete base with
rebar and mounting bolts per the US tower spec's
2. Is there a way to adapt any type of rotating guy device to this
type of tower?
3. I would also like to hear from SteppIR - US Tower users with similar
setups.
Plans are to erect the Tower some time in mid September or early October
depending on deliver time so I need to get the order underway.
Maybe I can improve on the ratings by not keeping the Tower raised to
the maximum height unless I am chasing some DX expedition or am I dreaming?
