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
