Hi

Does anyone know the specification of the coax cable for VM installations, and or where any decent cable may be purchased (approx 20-25m)?

Background info -
I installed some PH100 cable in part of my build around 5 years ago, but we're only now getting around to completion. Hooking the V+HD box today I saw some problems with a high signal loss so will need to replace. Maybe the cable is pinched or something.

The V+HD Box shows a 32 dB Signal to Noise Ratio (SNR), through a 6.1dB 3-way splitter at the wall and a 34 AGC signal level. However, at the end of the cable (direct to the wall) I'm seeing 22dB SNR and 58 AGC. This is only enough to view SD channels and the box will not go online, in fact if I try though a 3dB 2-way splitter, even the SD picture breaks up. Through the 3-way (which will need to happen) i get nothing.

Please only post with regard to this specific question.

Cheers,
