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 (P I /P O = 2/1)

Coax Cable Design - Electrical VSWR (Return Loss): –Voltage Standing Wave Ratio –Measure of electrical uniformity (Z O ) 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 ® Cable Benefits Flexible Non-kinking No water accumulation (air-dielectric) Easy connector attachment Easy installation Loss comparable to corrugated copper cable and air-dielectric cables

Added Protection with DB Cable Flooding compound seals braid from water ingress Passes industry standard water blocking tests No problems with connectors DB is standard on LMR-900 thru LMR year warranty

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) Lower loss than 9913 Comparable loss to 3/8” corrugated Foam PE vs airspaced PE dielectric (9913) No water accumulation (9913) 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 types

Attenuation Comparison LMR /8” corr LMR-600 LDF4 superflex GHz (dB/100ft)

LMR-900-DB (between ½” and 7/8”corrugated) 2.0 GHz: 1/2” corr LMR-900-DB 7/8” corr Cutoff Frequency: 6.9 GHz No impedance change at bends Excellent selection of TMS connector types

LMR ® Connectors Interfaces - N, TNC, SMA, BNC Body Attachment - Crimp, Clamp –Crimp - quick install - crimp tool required –Clamp - field install - no special tools Pin Attachment - EZ nonsolder (spring finger) or solder Tools - strip, crimp, wrenches

VSWR vs Frequency

EZ field Connectorization Requires only a trim tool, crimp tool < 5 minutes to install 2 connectors Time & $$$ savings Reliable connection

LMR ® 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”
