Am Ground Systems Co.m
 

Competitive Pricing and Quick, Reliable Installation

AGSC  builds ground systems for AM transmitter sites and lightning protection at any site.

AGSC is a division of KK Broadcast Engineering located in Lawrenceburg, TN.  KK Broadcast Engineering has been providing quality radio engineering services to the southeastern US since 1983 and has built, evaluated and repaired numerous ground systems across the eastern US.

THE SCOOP

In normal soil, an AM ground system constructed using #10 soft drawn copper wire will last approximately 30 years. Highly acidic or extremely rocky soil may cause radials to fail in as little as 10 years or vandals can "recycle" your ground system in just a few hours.  Unknowing (or uncaring) excavators can ruin a ground system in minutes.

If your ground system is over 30 years old, has been vandalized or damaged by construction, call or email AGSC for a ground system evaluation estimate.

If you are moving an AM transmitter site or building a new station, contact AGSC early for information and a quote.  A few minutes planning now could save you days of work and big $$$ later.

Ground system evaluation and repair is performed on a time and material basis or per project if desired.  If only a few radials have been damaged, new radials can be plowed in, but other undamaged radials may be disturbed by the plowing process. Depending on the nature and scope of damage, AGSC has specialized equipment to locate the ends of broken radials and repair them.  If a substantial portion of your ground system (25%) has been damaged, it is often necessary to completely rebuild the entire system.

Ground system construction is quoted on a per project basis with ALL desired services,  ALL expenses,  ALL required materials included.  This includes services such as plowing, brazing, trenching, well attachment or tower tuning.  Expenses like  travel, lodging, etc.  Materials such as wire, ground screen, ground cover, ground rods, copper strap, clamps, brazing alloy and gas.

When AGSC quotes a complete ground system the price is all inclusive...  NO surprise charges that some contractors will present you with.  NO requests for extra money to rent needed equipment. NO asking for extra money to purchase supplies.  AGSC knows that in today's corporate and small business environment that you need to know EXACTLY what a project is going to cost before you start.  You can depend on AGSC to come in at or under your budgeted costs.

All equipment normally used by AGSC is owned by AGSC and transported to the job site by AGSC.  Specialized equipment is obtained at the expense of AGSC.  All AGSC owned equipment is well maintained and reliable.  Having breakdowns on the job site, hunting for a suitable piece of equipment to rent and waiting for that equipment to arrive wastes both of our time and puts YOU behind schedule.











Our plow is designed to carry the roll of wire and plow at a constant depth for the entire length of the radials.  This method creates much less stress and stretching of the wire.  This translates into less breakage during installation and longer life for your ground system.  The most important advantage of this method is that the radial end is buried at the same depth as the rest of the radial.  Contractor's using a plow that pulls the wire from a roll at the tower often leaves several feet of the wire visible on top of the ground and almost always leaves the outside ends exposed to vandals... Not a good thing!
 
 

Beware the exceedingly cheap quote.

AGSC can usually begin construction in as little as 1 week depending on availability of materials.  We keep some wire and strap in stock for emergencies and can obtain all other materials in 2 weeks or less.  All work is done in a timely manner and usually in ONE trip to the job site.  A typical ground system with screen and cover can be built in less than one week and can take as little as 3 days.  Unlike many of our competitors, AGSC has ALWAYS been on time to begin construction and the project has ALWAYS been completed in the time frame quoted...
NO EXCEPTIONS.

By now you may be wondering, "How did a full time broadcast engineer get into the glamorous business of building ground systems?"       Sort of... by accident.     Sort of... by necessity.   Click HERE for the gory details.
 
 

Which would you rather have build your ground system?  A competent broadcast engineer led crew of professionals using the proper equipment and materials?  Or a fly by night outfit using whatever equipment and materials they can beg, borrow or steal(!).

The following photo's were shot at a turnkey AM site installation for WBCF in Florence, AL. This ground system consisted of 120 quarter wave radials (200 ft at 1240 kHz) with 120 interspersed 50 ft radials for ground concentration around the tower base. To further enhance the ground field around the base of the tower (the point of maximum ground loss) a 48 ft by 48 ft ground screen of expanded copper mesh was laid on the ground and covered with 10 year landscape material and limestone gravel. The mesh and all ground radials were connected to a circular ground connection point connected to the tower base with 4 each 4 inch copper straps. Numerous 8 ft copper clad ground rods were driven around the connection point and a 4 inch strap was connected to a 115 ft deep (steel cased) well drilled about 4 feet from the tower base. All copper/copper connections were made using 15% Silver/Phosphorous/Copper brazing alloy for extremely long life and excellent conductivity. All copper/steel connections connections were made using regular brass brazing alloy or special clamps.

The rather large shadow in the preceding pictures is that of AGSC owner Kevin Kidd.  The skinny guy in the
pictures is Shelton Barnett chief assistant and paramedic (he's a full time fireman).  While building another ground system
in Alabama, Shelton and I had to render first aid to the station engineer for a piece of wood  that he had accidentally stuck about 3 inches into the calf of his leg.
