Static Dissipaters for Towers and Buildings

Static Dissipaters

These products are very similar to the Cortana Static-Cats that you may be familiar with.  

Static dissipaters bleed off static charges that build-up on towers.  The end result is they prevent lightning strikes or reduce the intensity of any strike that may occur.

The EN-1 Eagle Nest Static Dissipater is for towers typically taller than 200 feet. Each one has 420 stainless steel points, 1/8" diameter, on the top and 420 points on the bottom.  Each side of the nest is 30".  Four 5/8" x 4' stainless steel all-thread rods mount it to the top of a tower usually surrounding a beacon light.  Standard procedure is for a tower worker to install the EN-1 using the existing four bolt holes that the beacon uses. 

The photo on the right shows two men installing one on a tower.  The job took about an hour.   

The price is only $1200.00.  This is a quality product that is worth the cost and much more. The shipping weight is 30 pounds.

There is a crossbar to go across the top of the EN-1 that has more stainless steel points.  That option is $350.00.

The Gila Stat GS-3 is typically used at 200 foot intervals on towers.  It has a 2" x 17" aluminum bar with 60 1/8" stainless steel rods sharpened to points on the top and 60 more on the bottom.  A 5/8" x 24" all-thread mounting rod is included.  The cost is $300.00.  Shipping weight is 8 pounds.

Note: You need to specify the leg diameter of the tower it will go on.  If it is an angle-iron tower, then specify a bolt hole diameter that is currently being used on the tower at the height where the unit will be mounted.  You will need to remove that bolt and re-insert it through the mount of the Gila Stat.  Also, specify if the hole is on the side or top of the tower.  The mount is included in the price.   

The cost is only $195.00.  It comes with a mounting bar and is shown here attached to the side of a tower.  You need to specify the diameter of the round-member that it will attach to.

The Gila Stat GS-1, with 12" long mount, sells for $79.00.  A Gila Stat GS-1 with 36" mount is $89.00.  In either case, you need to specify the diameter of the tower leg that it will attach to.    

Use these on 100 foot towers, tops of buildings, and on guy lines of taller towers to keep static charges from snapping across guy insulators.
