2.5. Mounting the Radial Connection Box:
In 2016 Spiderbeam replaced the big bulky aluminum Radial Connection Plate with this smaller
Radial Connection Box (RCB-1). The RCB-1 is easier to mount to any size fiberglass mast and has
plenty of connectivity for radials.
The picture on the right shows 8 radials, 4 radials
per side. In this example we have connected 2
radials per solder lug.
For more connectivity you may solder up to 4
radial wires to each solder lug and you may
connect up to 10 solder lugs per side
–
giving
you a maximum connectivity for 80 radials.
Should you require more radials, contact
Spiderbeam for a Radial Expansion Adapter.
NOTE: The RCB-1 and radials will be mounted
AFTER the pole is fully erected and properly
guyed.
(Paragraph 3.5, page 25)
Proceed as follows:
Fasten the pole to the wooden base stake, pulling the top strap tight, but leaving the
bottom strap loose. This will enable you to pull the pole a few centimeters away from
the stake for installing the radial connection box (RCB-1).
Place the RCB-1 against the pole near the bottom, approximately 10cm (4 in.) above the
ground.
Fasten by wrapping a large black (UV-Resistant) Wire-Tie around the RCB-1 and the
fiberglass pole, being careful
not
to wrap around the wooden stake. If you don’t have
a
large enough wire-tie, use two medium-size wire-ties.
Now you can secure the Spiderpole to the wooden stake by tightening the lower strap.
Connect radial sets to both sides of the box. (Now, or at the end of the installation.)
o
For portable installations, fasten using Wing-Nuts, Washers, and Lock Washers.
o
For permanent installation, secure with standard Nuts, Washers and Lock Washers.
