STAGES OF MANUFACTURING
|Aluminum coils shown above are purchased in large volumes,
typically around 40,000 lbs. per size. We use a 3003.0 temp coil which comes direct
from the mill
All aluminum must go through a circling process as we are doing above. This requires that each individual piece is handled by our trained technician.
|Equipment selection, material prep, welding technique, visually inspecting weldments to ensure high-quality gas-metal-and gas tungsten-arc welds on aluminum alloys are key to quality product. Even for those experienced in welding steels, welding aluminum alloys can present quite a challenge.||Metal spinning is a metal working process by which, in our
case, the large flat circle aluminum is placed on the mandrel above. A trained tech
then applies a wheel with pressure that is controlled by computer, to lay out
the aluminum so that it forms (work hardens) to the mandrel. We use extreme care to
measure the pressures of each spinning.
|Mandrels can spin various sizes of aluminum thus giving you a different focal diameter than what we offer as standard. Notice that mandrels are made of both steel and wood.||Should you have a special need we can offer you
the option to purchase a mandrel / tooling that we cut from a block of wood. The
mandrel above was once a large square chuck of wood that has been cut at our factory by
our trained professionals.
|Antennas, once spun, must go through a cleaning
process that requires acaustic alkiyd wash, bath rinse, priming and than
painting. We than hang the antennas to dry as we show above.
Standard color is beige and we do offer custom color for an additional fee.
|Steel is purchased in large volume. We custom cut each piece to our specs. The carbon content is most important factor of steel for weldability. We use both spot and seam welding. This welder has over 15 yrs experience in welding.|
|Stacking of the ring for these mounts help to
eliminate space that is required for storage in the warehouse. Typical stacking
above also shows how we can ship economically for large volume orders.
|We warehouse a fair amount of our standard inventory as shown above. This allows for DH make manufacture in large quantify which helps reduce your cost.|
|The Dual Powered Gibralter mounts above are our Top-of-the-line mount. These units are massive in size and are stored in upright position until shipped. Motors are protected with special wrap to eliminate moisture from entering while stored.||This is the finished DH antenna with our Galvanized Dual Powered Gibralter. DH offers "Installation Assist" for all antennas. Your antenna can be handled by DH from beginning to end. Ask for details.|
