TESSCO Technologies has been around since the 1950s as Towson Engineering Supply and Sales Corporation, but it wasn’t until the current CEO took over in the early 80s that it began to become what it is today. What is it? Your total source for anything wireless. Do you want a new faceplate for your phone? TESSCO can help. Do you want to put up a broadband security system around your business complex? Again, TESSCO is the place. The catalog for this company is bigger than a phone book – and it is set up so you can do side by side comparison shopping of the various brands. Since there is so much, the easiest way to shop is on their website – www.tessco.com.
