[QUOTE="Robbo, post: 520149, member: 256551"] Not sure what 120dB refers to, it is probably the screening. On a long cable run, the important factor is the attenuation per 100m. The usual benchmarked '100' type cable has an attenuation of 32.5 dB per 100m, and is supposedly good for up to 30m to 40m. The lowest attenuation benchmarked '165' type cable has an attenuaton of 22 dB per 100m. By my reckoning the '165' type should be OK for 60m without any additional components. wf165 is an example of it. Robbo:) [/QUOTE]
