Welcome to another NEW HIGH QUALITY product from Stryker Radios! The SR-A10 was designed after the A-10 Thunderbolt "Warthog" known for it's huge Gatling Gun making up the entire front nose. The Stryker SR-A10 has been tested by many over the last 2 months with MANY reviews and NOT one single negative review over performance. In fact ALL of our customers have stated reviews, tests between their other antenna and the SR-A10. This IS an unbelievable antenna with that "Perfect Q" that has many turning and scratching their heads at how much quieter this antenna is until someone talks. ALL reviews thus far as of 6/27/2016 have been rave reviews to say the least! Louder clearer audio, better receive, and quieter than all others customers have tested against. 3/8 24 thread center load trucker style antenna. IN STOCK for immediate shipping!!!
