2.3 RF Cabling Requirements
 For all coaxial connections to/from the Repeater - high performance, flexible, low loss
50Ω coaxial communications cable.
 All cables shall be weather-resistant type.
 Cable length - determined by the Repeater installation plan. When calculating the cable
length, take into account excess cable slack so as not to limit the insertion paths.
 Make sure that cable and connector are compatible. Using cables and connectors from
the same manufacturer is helpful.
 All connectors must be clean and dry
 Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable
substance as moisture and dust can impair RF characteristics.
 Make sure enough room has been allocated for the bending radius of the cable. RF
cables must not be kinked, cut or damaged in any way
 Connect the RF cable to the antenna tightly but without damaging threads
 Fasten cables tight to cable ladder or aluminum sheet
 For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose
thicker coax cables for lower attenuation. Minimize the length of the coax cables to
reduce the attenuation
 Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each
end with a jumper cable.
