Shively Labs 6810 Replacement Manual

Model 6810: Replacing an Old (Brown) Partial Radome
with the New (White) Style

Step 1: Remove the bay assembly from the feedline

Whenever a rigger is on the tower in the area of the antenna, shut off the
power and lock it off so that it cannot be turned on accidentally.
Do not disturb the feed strap (1) at any time during this process. If you do,
the antenna will not perform well.
1. Shut off all power to the antenna and any other antennas on the tower.
2. Depressurize the system.
3. Mark each radiator with its position in the array. Radiator number 1 should
be at the top. NOTE Closure plate screws are usually 1/4" hex, but may be
round-head. If they are round-head and the feed strap is in their way, take
great care not to disturb the feed strap.

4. For each antenna radiator: remove the screws (2) securing the closure plates (3) to the partial radome (4), and
remove the closure plates.
5. Remove the hose clamp (5) securing the saddle (6) to the feedline (7).
6. Inside the partial radome, remove the flange nuts (8) from the feedline
studs (9).
7. Remove the entire bay assembly from the feedline.
8. Leave the inner conductor connector (10) in the feedline. If it comes off
with the bay assembly, pull it out and re-install it in the feedline.
9. Carefully lower the bay assembly to the ground.
10. Seal the baymount (11) with a protective cover to keep dirt out. If you
wish, you may purchase a cap flange from Shively Labs.
Step 2: Remove the old partial radome from the ra-
diator
1. Inside the partial radome, remove the two bolts (1/2" hex) securing the
antenna mounting saddle (6) to the antenna radiator.
2. Remove the plastic spacer between the back of the radiator and the
partial radome.
3. Remove the two small screws (12) at the sides of the partial radome
and spread the radome so that the front clears the antenna arms and the back clears the mounting flange.
4. Lift the partial radome off over the top of the antenna radiator.
