What is the dB loss for PowerMax low loss coaxial cable when comparing the different lengths?
Solution

Cable is a very important part of an installation. The dB loss of the cable selected must be examined to minimize signal loss. All Digital Antenna PowerMax amplifiers and repeaters must be used with 50 ohm cable. Cable should be laid as straight as possible since bends or sharp curves greatly decrease performance and may cause drastic or complete signal loss. Each end connector attached to the cable will produce 0.5dB of loss.

The following table outlines dB loss for PowerMax low loss cables at 850 and 1900 MHz:

Cable Loss @ 850 MHz Loss @ 1900 MHz
10' DA240 low loss 50 ohm cable 2.0dB 2.5dB
15' DA240 low loss 50 ohm cable 2.4dB 3.2dB
30' DA240 low loss 50 ohm cable 3.9dB 5.4dB
50' DA340 low loss 50 ohm cable 3.9dB 5.5dB
75' DA340 low loss 50 ohm cable 5.4dB 7.7dB
100' DA340 low loss 50 ohm cable 6.9dB 10.0dB
