Assembly

Note: Be sure to assemble from upper element. If the antenna is

being assembled from lower element, element can not be pulled

out from outer shell and fastened properly.

1. Put special wrenches on upper and center FRP outershells as

shown in Fig. 1. Use small diameter section of the wrench.

2. Connect upper element in the upper FRP outershell and center

element in the center FRP outershell with screwdriver.

3. After connecting these two elements in the outershells,

fasten upper FRP outershell joint bracket with special

wrenches as shown in Fig. 3.

Fasten the bracket thoroughly until there is no gap between

each part of the bracket.

4. After fastening the bracket, detach the wrenches from the

outer shells as shown in Fig. 4.

5. Connect center element in the center FRP outershell and

lower element in the lower FRP outershell the same was as

sections 2 and 3, but use larger diameter section of the

wrenches as shown in Fig. 5.

6. Attach three radial elements with the wrench as shown

in Fig. 6.

7. Attach mast brackets on support pipe and fix them.

8. Attach assembled antenna on mast as shown in Fig. 8.

While installing, be sure to take the balance of the entire

antenna into account.

9. Connect coaxial cable with connector to feedpoint section at

the bottom of the antenna through waterproof sleeve as

shown in Fig. 9.

10. After connecting coaxial cable, fix waterproof sleeve to the

bottom of support pipe with a screw.

Turn connected coaxial cable once to make a loop right below

the antenna as shown in Fig. 10 to escape excess load from

the cable.

Adjustment

The X500HA and X500HNA antennas are completely adjustment

free. If VSWR of the antenna is extraordinarily high, most likely

it is due to coaxial cable and connector contact, or a connector

soldering problem. Be sure to use 50Ω coaxial cable to feed the

antenna.

Note

Though the X500HA and X500HNA are DC grounded structures,

circuit across the inner conductor and outer conductor is open-

circuit when measured by a volt-ohm meter. If it is close-circuit,

confirm coaxial cable connections. Use the antenna vertically. If

the antenna is tilted, it can not perform perfectly as it is expected.
