• Tower Feeders
• In-Building Feeder Runs
• Rooftops
Coaxial Cable - Basics
• Coaxial cable is used to move (transmit RF
energy (power) from point “A” to point “B”
with maximum efficiency (minimum loss)
• Minimum loss = maximum power to the
antenna for optimum coverage (footprint)
• Tradeoffs are size, handling and cost versus
minimum loss
Coax Cable Design - Electrical
• Attenuation (Loss):
– Measure of efficiency
• The larger the cable, the lower the loss
• The lower the loss, the higher the efficiency
– Loss (dB) = 10 x log (Power In/Power Out)
• 0 dB (no loss) = 100% efficiency
• 3dB loss = 50% efficiency (PI/PO = 2/1)
Coax Cable Design - Electrical
• VSWR (Return Loss):
– Voltage Standing Wave Ratio
– Measure of electrical uniformity (ZO) versus
frequency
– The lower the VSWR, the better
1.10:1 up to 1.30:1 is typical for LMR - 98% to
99.8% efficient
– Field measure of system “goodness”
LMR Cable Design Features
• Center Conductor:
– Solid Copper, Copper Covered Aluminum or
Copper Tube
• Dielectric:
– Closed Cell Foam Polyethylene
• Shielding:
– Aluminum Tape Bonded to the Dielectric with
Tinned Copper Braid (>90 dB Shielding
Effectiveness)
• Jacket:
– UV/Sunlight Resistant Black Polyethylene
designed for 20 to 40 year service life

®
LMR
Ultraflex Cables
• Stranded center conductor for
easier bending and flexibility
• Thermoplastic rubber outer jacket
for enhanced flexibility
• Perfect for applications requiring
installation in tight areas
– NOTE: Cannot use EZ connectors;
not for repeated bending & loss is
15% higher than standard LMR
LMR®- FR Cables
• For installation in vertical building
risers, access and service shafts.
• Flame retardant low-smoke
polyolefin jacket
• Meet NEC Code Requirements
(UL/CSA CMR/MPR listed)
• Uses same connectors as standard
LMR cables
®
LMR
LLPL Cables
• Perfect for In-Building
Installations
• Meet NEC Code Requirements for
Plenums and Air Handling Spaces
and Air Returns (UL/CSA CMP/MPP
listed)
• Non-Solder EZ Connectors and
Solder-On Connectors Available
LMR-400 (vs 9913 or 3/8” corrugated)
•

No impedance change at bends (9913/3/8” corr)
Excellent selection of TMS connector types
LMR-600
(vs ½” corrugated or ½” superflex)
•
•
•
•
Much lower loss than superflex
Comparable loss to ½” corrugated
No impedance change at bends
Excellent selection of TMS connector

EZ Connector Install
Tips (LMR-400 & 600)
• Recommend using EZ Prep/Strip tools
• Debur the center conductor
• Make sure connector body is pushed
all the way onto the cable – look for
braid protruding
• Crimp directly behind the connector
body
• Don’t double crimp
• Give it the “Pull test”
LMR Factory Built Assemblies
• Fabricated from DB cable
• Sweep tested for Insertion
Loss and VSWR
