Coax Loss Specifications

Coax Cable is available through Radioware in several 50 & 75 ohm types. Recommended coax types for several Coax 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.

900MHz	27.9 B	20.1dB	12.6dB	7.7dB	6.0dB	5.4dB	4.9dB	4.2dB
1GHz	32.0dB	21.5dB	13.5dB	8.3dB	6.1dB	5.6dB	5.3dB	4.5dB
Imped	50ohm	50ohm	50ohm	50ohm	75ohm	75ohm	50ohm	50ohm
* 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!
