Tower leg ground fixture

Ground both your tower and coax shields at the same time!  Ground fixture attaches to any round leg tower or mast 1”-2” in diameter with supplied stainless steel vee bolts.  Ground fixture is 1/8” thick CNC laser cut 304 stainless steel for corrosion protection, and comes pre-punched for four PL259 bulkhead connectors (included!).  Also included is a copper ground lug which fits up to #2 copper wire, to provide a ground path from the tower to a ground rod.  If you prefer to ground the fixture with flat copper strap rather than round wire, your copper strap can be pinched between the bracket and the rectangular clamp (included) using the U-bolts to provide the pressure.  The other end of the copper strap can be attached to a nearby ground rod using one of our ground rod clamps.

Zinc tower leg to wire clamps
Tower leg to flat copper strap clamps
 

These clamps allow a low inductance copper strap attachment to  your tower leg.  Galvanic corrosion is prevented with an integrated stainless steel buffer between the copper and the tower leg.  Entire worm drive clamp is stainless steel (including the screw mechanism) to guarantee a long life.  Clamps fit tower legs up to 2” and copper strap up to 2” wide.  Two band model also available with double the clamping pressure.

Crank up tower grounding fixture

Finally an easy way to ground both your crank up tower and your coax shield at the same time!  Ground fixture attaches to your crank up tower under a 3/4” bolt or nut on the leg of your tower.  Ground fixture is made from stainless steel for corrosion protection, and comes pre-punched for four PL259 bulkhead connectors (included!).  Also included is a copper ground lug which fits up to #2 copper wire.  In addition, the fixture comes with a copper liner for improved conductivity of the bulkhead connectors and ground lug.  If you prefer to use flat copper strap rather than wire, copper strap can be sandwiched between the copper liner and stainless steel for connection to a nearby ground rod using one of our ground rod clamps.

Alpha Delta ground bus wall mount

Copper Ground Bus Wall Mount is a very rugged device for mounting up to 4 Alpha Delta Model TT/ATT3G50 series broadband coax surge protectors. Heavy gauge (.0937, 13 ga.) copper prevents twisting or flexing from the weight of long coax cable runs. Comes with copper bar, two copper ground lugs for #4-14 size wire with stainless mounting hardware, and  two ring terminals with stainless mounting hardware.  User supplies own wall mounting screws or anchors.  Alpha Delta surge units attach with stud mounts supplied in original packaging.


Ground Bus Wall Mount (GBWM)
Crank up tower ground lug and point

Inspired by N3XF, this stainless steel bracket allows a simple way to ground your crank up tower by utilizing one of the 3/4” base mounting bolts at bottom of your tower leg. Similar to the ground fixture above, but without the bulkhead connectors for coax.    Includes a copper lug for up to #2 ground wire.

Price:

$39.95

$4.00

Clamps are tin plated cast bronze, with stainless steel hardware.    Will accept #6 to 0000 gauge.  Fits .75” to 1.7” tower legs  (Rohn 25 and 45, and 55.)  Wire can position vertically or horizontally on the clamp for maximum versatility.  Rated for direct burial, even in concrete! UL listed.


A stainless steel shim is available if needed to put between the tower leg and the clamp to prevent dis-similar metal corrosion, recommended for aluminum towers.

Heavy duty tower leg clamp

Our heavy duty tower leg clamp allows a tight, secure method of bonding flat copper strap or ground wire to a tower leg using two T bolt style band clamps.  Galvanic corrosion is prevented with included stainless steel buffer between the copper and the tower leg.  Unlike traditional hose clamps, the heavy duty tower leg clamp uses T-bolts to tighten a 3/4” wide band around the tower leg, and secures with a stainless steel nylock nut.  Entire clamp is 300 series stainless steel, including the T bolt and nut.   Clamps fit tower legs 1.25” in diameter (Rohn 25g, 45g) or 1.5” in diameter (Rohn 55g).  Sizes are specific; please inquire if you have a tower leg that is NOT 1.25” or 1.5”.  Can fit copper strap up to 2” wide.

Harger beam clamp for round rod                          

Price:

$24.95

`Similar to above, this version can be used on tower cross bracing up to 15/32” or .460” in diameter.  This  is perfect for crank-up towers which are difficult find a suitable place to attach ground wires. Clamp is tin plated for corrosion and dissimilar metal protection, and will accept a wire up to #0000 (4/0, or 1/2” diameter wire!). Anti oxidant grease around wire and tower leg such as Penetrox-A is recommended.  UL listed.  Approx. 1 3/4” x 2”.


Similar to the ground lug above, the Crank Up Tower Ground Point comes with an additional square piece of stainless steel to sandwich copper strap, providing a low impedance path to ground.  Requires drilling of the copper strap, easy to do by using the existing holes in the unit as guides.  Comes with hardware AND also comes with a wire lug, so you can also ground a wire with it.   Fits up to 2” wide strap.
