Hi Brent, In my experience from sourcing and testing many standard HDMI cables it is very difficult to get a good quality shielded cable without working closely with the vendors. At the very least a copper foil backshell with good solder termination should be specified but better performance can be had with an all metal two part backshell.
Most of the products sold through Amazon, eBay, etc. are generally unshielded or poorly shielded. I even tested some expensive super Hi-Fi HDMI cables that retailed for $30 for 1m and they were just as bad as the rest. Ones with moulded "ferrites" on them were often found to perform the worst. I would try and find parts from a reputable manufacturer, perhaps Molex, Amphenol and try them. Be prepared to buy and test several samples before you find The One. I hope this helps, James -----Original Message----- From: Brent DeWitt [mailto:[email protected]] Sent: 24 August 2015 16:49 To: [email protected] Subject: [PSES] HDMI extension cable recommendation? I’m looking for a good quality HDMI extension cable for test use. Price is not an issue since I only need a few. Does anyone have any recommendations based on their shielding and build quality? Thanks!
