Once the "theoretical" engineering phase is complete, the product is ready for the "practical" testing phase and manufacture. SWR maintains an antenna test range for FM directional antenna modeling and UHF pattern optimization. Test range measurements and extensive near-field techniques are used to determine the free space pattern measurements. Test data is recorded by a computer, then saved to a floppy disk for future record. Through the use of a complete line of adapters and transition devices, SWR is able to measure and connect to most systems, regardless of the manufacturer. In manufacturing, we maintain a series of rigid quality control steps to assure the products we make will perform according to specifications. That means you can count on SWR to deliver the product you need, when you want it. Efficient production standards also mean we provide a quality product at a price you can afford. When choosing a material for each product, SWR looks at the relevant properties of available choices and selects the best practical material for the intended use. High-purity, heavy-wall copper is selected for the transmission line inner connectors because of its excellent conductivity characteristics. By selecting this material, we can provide a better product that features low loss and high thermal conductivity for greater heat dissipation. That is an important factor when the objective is to get the highest quality signal to the antenna. Once the antenna is assembled, it undergoes a Return loss test to determine the VSWR of the antenna. The company retains experienced and qualified technicians and engineers to assure that the product is properly tuned and tested before leaving the company dock.
