Stryker products are known for rugged reliability and the center-load SRA-1020 is no different. Uniquely designed to be used with either a 10" or 20" lower shaft, the SRA 1020 includes two 10" stainless steel lower shafts along with a coupler to connect both shaft pieces together for a 20" shaft if needed.  Use the longer shaft if you need the length to get the antenna coil over the roofline, or if you just want the antenna coil to be higher in the air. This is a wide band antenna that easily covers both 10 and 11 meter bands, 26.965 - 30 Mhz. Other notable features are the double waterproof coil cover, 10,000 watt rating, and 6 gauge silver plated coil.
