This is how a quality CNC machined long lasting antenna is manufactured. Starting at the top..Delrin lower coil support with .750 inch of oil lite bronze for a nut, 3/8 inch Stainless allthread, threaded clamping collar, bearing housing with two double sealed ball bearings, threaded clamping collar, magnet support ring/motor coupling, Delrin motor support housing and finally the Industrial grade robot motor.
We use only the finest materials for our antennas. Our customers comment on just how well they are built. Our antennas cost more to manufacture than the other guys but we know our antennas will be around for many years to come.
Below is a chart on how strong the Delrin is we use.
