The V2000A is the U.S. version of the V2000 Tri-Band Antenna. This antenna has been optimized for the U.S. FM Bands. The V2000A utilizes a linear phase shift design to couple the different frequency band sections together. A watertight joint assembly connects the two antenna sections into one rigid assembly. The resulting antenna has the same strength as a one piece structure. This is the ideal antenna for FM operation on 6 meter, 2 meter, and 70cm bands. Similar in construction to the X200A dualband, the V2000A has an additional counterpoise radial -- adjustable for 6m (52-54 MHz only). With 6m activity, enjoy the freedom of 3 bands in one compact antenna. Special Features: • Fiberglass radomes • Overlapping outer shells for added strength • Strong waterproof joint couplings • Stainless steel hardware • Wide band performance • Highest gain • High wind rating • DC ground; antenna element and radials connected to mounting pipe • Three radials • One Year Limited Warranty against defects in material or workmanship Specifications: Bands: 6m/2m/70cm Frequency (MHz): 52-54/144-148/440-450 Gain: 2.15dBi/6.2dB/8.4dB Impedance (nominal): 50W VSWR: 1.5:1 (typical) Power Rating: 150 watts Element Phasing: 1/2l/2-5/8l/4-5/8l Max Wind Rating: 112 m.p.h. Mast Dia. Acceptance: 1.2 to 2.4 inches Length/Weight 8.3 ft./2.6 lbs. Connector: SO-239 Female Remarks: Diamond® MX2000 triplexer is required for multiband operation.
