Diamond Antenna V2000A Instructions

Diamond Antenna Products
The V-2000A is the U.S. version of the V-2000 Tri-Band Antenna. This antenna has
been optimized for the U.S. FM Bands. Diamond MX-2000 Triplexer is required for
multiband operation.
The V-2000A utilizes a linear phase shift design to couple the different frequency
band sections together. The antenna functions as a 1/2 wavelength counterpoise,
two 5/8 wavelength elements are 70cm. A watertight joint assembly connects the
two antenna sections into one ridged assembly. The resulting antenna has the same
strength as a one piece structure.

1. Remove antenna sections from package and note how sections are tapered to
fit together at the Section Joint Assembly.
2. Upper & Lower Section Joint Assembly. Lay the Upper and Lower Sections
in a line end to end. Connect the antenna elements at the Element Joint as
seen in Figure 2. Tighten the two set screws. (It may be necessary to slide the
brass antenna element slightly out of the upper section in order to fit into the
Element Joint Coupler.)
3. Carefully insert upper fiberglass section into lower fiberglass section. The
black line should be touching lower section. Slide gasket holder down to meet
lower section joint. Verify proper seating of gasket. Threat upper joint nut
onto lower joint. Verify proper seating of gasket. Thread upper joint nut onto
lower joint. Do not overtighten.
4. Fasten radials and secure lock nuts. Figure 7 depicts 6m counterpoise.
5. 6m Adjustment. Support antenna about 10' above ground. Measure VSWR.
Adjust counterpoise radial length for best VSWR at desired operating
