Fernando asked: "What is the difference between Double Bazooka and dipole?" It's just a lot heavier than a wire dipole, more expensive, stretches over time to where it is no longer resonant and generally a disappointment. A fan dipole is usually superior in bandwidth, costs and longevity. 73, Ray LaRue, W4BYG VP Engineering Dominion Video Satellite, Inc. (SkyAngel DBS) Naples, Fl
