Coax Loss
Specifications |

Coax Cable is available through Radioware in several 50 & 75 ohm types. Recommended coax types for severalCoax Applications are also provided. The Insertion Loss chart is provided below for coax cable comparisions. Remember the higher the frequency, the more signal you lose for any cable type, so keep your cable lengths as short as possible. |

Note: Coax losses shown above are for 100 feet lengths. Loss is a
length multiplier, so a 200 ft length would have twice the loss shown above and
a 50 ft length would have half the loss. This multiplier factor is why you
should keep cable installation lengths between radios and antennas as short as
practical! |
