Ethernet cable is gonna look oogly - but it's cheap. The twisted pairs should provide a little shielding. The jacket will not be very smooth unless it's made from some material like TPE (rubberized thermoplastic). These are usually called Plenum Cables because of the rated temperature range. They're also round instead of the PVC-jacket-gets-twisted (and otherwise deformed) characteristic.
I would advise a fully shielded mic HOT and RETURN cable. The Pro stuff, like Shure used to source in the 1970's. Dunno who sells this class of mic cable now, but there was a distributor in Burbank, CA a long time ago that used to service the west coast NBC studio. I would look along those lines. At this station, there's been no trouble with the cabling for a Heil Goldline that Heil itself provides. It's a little pricey for someone that is mostly DIY, but your TX audio will never suffer from it. So even though you want to use the MH2, an extension in one of these two classes might cut it for you. You might look into Heil Audio; they may source an extension for the MH2 or its equivalent. I believe the idea would be to minimize the impedance from source to load, while keeping any stray RF away from the MIC input to the K3. At this station, I have a lifetime supply of the Shure cable. It's double-shielded with both a woven layer and a thick foil. That, and a few ferrite collars cover the audio here from RFI. Audio reports are good too, better than anyone has a right to expect. 73, matt W6NIA On Wed, 04 May 2011 23:57:48 -0400, you wrote: >I am getting ready to buy a K3 and a MH-2 hand mike. > >Due to the layout of my station, I need to add a 6-foot-long extension >cable from the K3 mike jack to the actual mike connection.
