Who We Are:

Keith S. Clark, d.b.a. Sandown Wireless

    Sandown Wireless is the Registered Trade Name of Keith S. Clark & Associates. We are located in the Northeast USA in the great State if New Hampshire. New Hampshire is known as the "Live Free or Die" State and is a perfect place to be in business. NO Sales tax and NO Income Tax has made New Hampshire a very competitive environment to function in. I'm personally retired from the Rockingham County Sheriff's Department where I served as the Department's Communications Technician. After 20 years I decided to go out on my own and use some of that experience to better advantage. I am also known by my "Ham" radio call sign WA1HZK. Hey, maybe I'll hear some of you on the air sometime?

     For the last ten years I have been in the Radio Communications Consulting and Equipment Supply business. I have an extensive background in the battery business previous to those government years and now partner with several key manufacturers to bring you the best quality batteries and communications products the industry has to offer. From portable Radios, Batteries & Accessories to custom built Communications Radio & TV towers, we do it all. Check our link sites for more details.

    We specialize in David Clark Co., Inc. & OTTO Headsets & Accessories to our Military and Public Safety Customers. If you need the military hardware from David Clark Co., Inc. or the Public Safety headsets & accessories from OTTO for your portables, you will find it here factory direct!

    On this Critical Radio site you will find no "On-Line" ordering. I encourage my customers to call me and talk to another human being about exactly what item they are looking for. This personal touch ensures that what you get the first time is what you need to do the job. If you know what you want then just print out the order form and either fax or e-mail it to us for processing. If we think you might have made a mistake, we will still call to talk over your project. We are factory distributors and as such I drop ship 100% fresh products direct from the manufacturer to you.

    We also specialize in exporting all of our products anywhere on the planet. If you need a skid of batteries shipped to Jordan or a radio tower delivered to Baghdad, we are your guys! Just give us a chance to quote. You will be surprised to find out how easy it is to do business with us.

You Will Be A Satisfied Customer, I Guarantee It!
