Welcome to the Stryker Radios company. This company is very quickly becoming one of the top 10-12 meter radios company of the future. We are very excited to bring their antenna line to Sky-Tronics and our customers. The Stryker line of antennas (SR-5K mag, SR-5K roof, SR-A10) are NOT manufactured by Wilson. Stryker antennas are built with original quality carried forward and carry TWICE the warranty AND for LESS money!!!
