These pictures show the installation of the radio tower and antennae at the station location (QTH) in North Las Vegas. The project occurred during April 2010. The tower is located on the north side of the house. The permit story is below the thumbnails.
Installation was in two parts, install the tower and install the antenna group; separated by two days to let the concrete set.
I rented a backhoe and hired a recommended operator and one assistant: cost $380, three hours. The backhoe was used to excavate and to lift the tower into position, but the bracket installation and tower tie-in, and positioning of the bottom of the tower to get it vertical ... I did it myself. The cement was mixed in the cement truck on-site, and poured the same day ... about 2 hours later: cost $180.
Two local hams (W9AYK and KE7WOD) and another gentlemen assisted with the antenna installation.
The big antenna is a Force12 C3S, just 14 lbs.

Permit Story: This installation is in North Las Vegas, which is in Clark County Nevada. It's also in a Homeowner Association.
In order to get approval of the HOA, one must first get the building permit. So I downloaded Rohn's technical stuff and found a couple of documents that were near matches to what I wanted to do. I already know that 32' would be max, due to proximity to other building, mainly my very accommodating neighbor.
Rohn's documentation calls out ANSI/EIA-222-F and EIA RS-222-C standards. The City Engineers had a cross-reference to their standards and approved the proposed installation. [ROHN: SS Self-supporting Towers, G-Series, 25G; and B Bracketed Towers. Both are downloads.]
This called for a specified footer and rebar configuration. I couldn't match it exactly because the tower would be too close to my house. So I specified an installation with my own computer generated drawings, that is a combination of SS and B.
At installation, i used 50% more cement footer than required, and the bracket was about four feet lower on the house than planned.
The permit was approved and I put a copy of it with the remainder of the HOA application papers and sent it to the HOA management company, and the Architectural Review Committee. It was approved in less than a day. I included a copy of the Nevada PRB-1 and a quote from the CCR regarding compliance with PRB-1. [Nevada made the FCC PRB-1 into law in Nevada. How cool is that?]
One final note: In NV, most HOAs are run by a contractor, mainly because it's nearly impossible to get owners to volunteer to serve on the Board of Directors; or do anything about the HOA except complain! When we bought this house and signed the papers, I already knew there was only one person sorta participating on the HOA. So, I volunteered and became the president of the HOA! The Architecture Review Committee was ... me. [The NV version of PRB-1 is very carefully worded, using the term "Governing Body", which can be taken to mean the HOA Board; but technically the term means a government governing body, not necessarily an HOA.]
