Transmission Line Support Systems
Antenna Support Bracket
for transmission line
Pipe-Leg Support Clamp
for transmission line
The Antenna Support Bracket angle mounts directly to a 41/2" (114 mm) OD antenna pipe mount or tower leg. This
is ideal for supporting transmission line runs close to the
antenna and for positioning the line to begin a vertical run.
B358 includes:
1 - 2" (51 mm) x 2" (51 mm) x 3/16" (5 mm)
Angle, 3' (914 mm) long
1 - U-bolt Assembly
1 - Channel Attachment
Clamps are heavy-duty 3/16" (5 mm) x 1-1/2" (38 mm)
galvanized steel formed to fit common tower-member
diameters. The pre-punched holes are used to attach
either Cushion or Butterfly Hangers or Coax Blocks using
3/8" hardware. Snap-in Hangers are supported using the
Snap-in Adapter (p. 2.02). Conduit runs and ground
wire can also be attached to the Clamps.
Included are two 1/2" x 1-3/4" bolts, nuts, and lock
washers.

Climbing-Ladder Support Bracket
for transmission line
The Bracket supports up to seven Snap-In Hangers for
support of coax transmission line on climbing ladders
built with vertical angle members. The Bracket attaches to
angle sizes from 2-1/2" (64 mm) x 2-1/2" (64 mm) to
4"(102) x 4"(102) and may mount on either leg of the
angle. To use cushion hangers, B1757 (p. 6.01) will
convert the 3/4" (19 mm) diameter hole to enable the use
of 3/8" diameter hardware.

Transmission line runs can be clamped directly to a round
tower leg or diagonal, as shown (Fig. A), by using two
clamp heads back-to back. The clamp heads must be
bolted together (Fig. B) before installing either the
Cushion Hanger or the adjustable Clamp. Threaded rod
standoffs may be used to extend the transmission line
away from obstructions, for either angle-leg towers (Fig.
C) or pipe-leg towers.

Heavy Duty Welded Coax Support
Ladder
with Angle Rail and Rungs
The Coax Support Ladder, in lengths of 5' (1.524 m), 10'
(3.048 m), and 20' (6.096 m), is provided in welded
sections, that include 2-1/2" (64 mm) x 2-1/2" (64 mm) x
1/4" (6 mm) angle rails, angle rungs, and hardware for
tower attachment. The maximum span between tower
attachments is 20' (6.096 m) Two hardware mounting kits
are provided with the 20' (6.096 m) ladder, and one
hardware mounting kit is provided with the 10' (3.048
m) ladder and the 5' (1.524 m) ladder. Each hardware
mounting kit includes two brackets and hardware to
attach the ladder to the tower.
There are two ladder widths available, 3' 1-1/2" (953
mm) for 12 runs of coax and 3' 10-1/2" (1.181 m) for 15
runs of coax. The rung spacing is 3' 4" (1.016 m) and has
3/4" (19 mm) holes for Snap-In Hangers and 7/16" (11
mm) holes for Cushion Hangers or Butterfly Hangers to
support coax transmission line up to 2-1/4" diameter.
Each ladder section is furnished with splices to interconnect with the next section. The ladder for round tower
members attaches to an 1-1/2" (38 mm) to 4-1/2" (1.231
m) OD round tower girt or diagonal with included
brackets and hardware. The ladder for angle tower
members attaches to a 5" (127 mm) maximum, girt or
diagonal, with included J-bolts and backing plates. An
optional J-bolt can be ordered when the angle tower
member exceeds 5" (127 mm). J-bolt part number B2335
(p. 14.04) will accommodate angle tower members from
5" (127 mm) to 7" (178 mm) in width.
When the Ladder extends to ground level below the
lowest girt, a Ladder Base Kit is required to support the
ladder at ground level. The Kit consists of stub angles that
either install in a concrete footing or bolt to a concrete
pad. Material is hot-dip galvanized after fabrication.

Bolt-Together Coax Support Ladder
with Angle Rail and Rungs
Coax Support Ladders are available in three lengths, 5'
(1.524 m), 10' (3.048 m) and 20' (6.096 m), and are
available in factory assembled or field assembled sections.
Each ladder section is constructed of angle rungs bolted to
1-3/4" (44 mm) x 1-3/4 (44 mm) angle rails and includes
the hardware for tower attachment. The maximum span
between tower attachments is 10' (3.048 m). Two hardware
mounting kits are provided with the 20' (6.096 m) ladder
and one hardware mounting kit is provided with the 10'
(3.048 m) ladder and the 5' (1.524 m) ladder. Each
mounting hardware kit includes two brackets and hardware to attach the ladder to the tower.
The ladder is available in two widths, 2' 8-1/4" (819 mm)
for 12 runs of coax and 3' 3-3/4" (1.010 m) for 15 runs of
coax. The rung spacing is 3' 4" (1.016 m) and has 3/4" (19
mm) holes for Snap-In Hangers and 7/16" (11 mm) holes
for Cushion or Butterfly Hangers to support coax transmission lines up to 1-5/8" diameter.
Each ladder section is furnished with splices to interconnect with the next section. The ladder for round tower
members attaches to an 1-1/2" (38 mm) to 4-1/2" (114
mm) OD round tower girt or diagonal with included
brackets and hardware. The ladder for angle tower members attaches to a 5" (127 mm) maximum, girt or diagonal,
with included J-bolts and backing plates. An optional J-bolt
can be ordered when the angle tower member exceeds
5"(127 mm). J-bolt part number B2335 (p. 14.04) will
accommodate angle tower members from 5" (127 mm) to
7" (178 mm) in width.
When the Ladder extends to ground level below the lowest
girt, a Ladder Base Kit is required to support the ladder at
ground level. The Kit consists of stub angles that either
install in a concrete footing or bolt to a concrete pad.
Material is hot-dip galvanized after fabrication.

Lightweight Support Rail
Combination Square Rail
Lengths of B240 or B251 Combination Square Rail can be
joined together with B252 Splices to fabricate a lightweight vertical transmission line support.
One side of the Square Rail is used to attach Cushion
Hangers at desired intervals using Spring Nuts and 3/8"
hardware. The other side attaches to the tower using
various methods, depending on the tower construction.
The recommended maximum span between tower
attachment points is 20 feet (6.096 m), based on a
loading of 20 lb (27.120 Nm) per lineal foot.
Transmission line runs of this type should be installed
near a climbing ladder or tower leg since the support rail
itself offers no footing for workers installing the linesupport components.
Rails are 1-5/8" (41 mm) square, 12-gauge (3 mm)
galvanized steel that is spot welded back-to-back. When
used for horizontal transmission line support, the top Rail
slot is used for attachment to Pipe Heads with 1/2"
hardware and 1/2" Spring Nuts (B262). The lower Rail
slot is used to attach transmission line with 3/8" hardware
and 3/8" Spring Nuts (B174). See page 6.01

Lightweight Support Ladder
with Square Rail
Vertical support ladders for self-supporting towers can be
fabricated using standard products, as shown. Ladders
are 3' 4" (1.016 m) wide and are attached to the face of
the tower. The recommended maximum span is 20'
(6.096 m) between tower attachment points. This is
based on a loading of 40 pounds (54.233Nm) per lineal
foot resulting from a 100 mph (161 km/h) wind load on
seven 1-1/2" (30 mm) elliptical waveguide runs.
Cross Pieces, for either Cushion Hangers or Snap-In
Hangers, are attached at desired intervals to one side of
Combination Square Rails using 3/8" Bolts and Spring
Nuts (p. 14.03). The other side of the Combination
Square Rails attach to the tower with 1/2" hardware.
Exact methods of attachment depend on the type of tower
construction. Lengths of the rail are joined together with
B252 Splices. Attaching hardware for the Rail and Cross
Pieces is ordered separately.

Cross Piece
for Square Rail Support Ladder
Cross Piece ladder rungs are available to support either
Cushion Hangers or Snap-in Hangers. The B291, fabricated
from 1-5/8" (41 mm) square rail, enables the attachment of
eleven Cushion Hangers using 3/8" Spring Nuts (p. 14.03)
and hardware. Multiple transmission line runs can be
supported in each Cushion Hanger, depending on the line
size.
The B1647, fabricated from angle steel, provides sixteen
3/4" (19 mm) holes for installing Snap-in Hangers. The
hole spacing of 2-1/2" (64 mm) on-centers allows 16 runs
of up to
1-5/8" coax to mounted on each Cross Piece.
Both Cross Pieces are 3' 4" (1.016 m) long and are hotdip galvanized steel.
Adjustable Clamping Bar
The Adjustable Clamping Bar is used to support vertical
transmission-line runs and to terminate horizontal
bridges on the face of angle leg towers. This is an extremely versatile product. Slots in the Clamping Bar allow
it to attach to a variety of tower widths.
Galvanized.
Adjustable Clamping Bar includes:
1 - 4' 4" (1.321 m) long Clamping Bar
