I recently (within the last 2 months) had a contractor run some coax cabling in my apartment while he was doing some other work. My digital cable (Time Warner in NYC) works, but about 30 channels do not work or work very sporatically. The TW technician told me that he thinks that I have R-59 cabling in the walls.

Before I pay to have the contractor come back out to price the costs of upgrading to R-6 cabling (plaster walls), i thought I'd check with you all to see if there is anything that I can do to improve the signal in my existing cabling.

My fault for doing some research beforehand.

Thank you in advance.
