Had a D* tech out today to align dish (got a call from D* saying I had low signal). I have R59 in the house and currently using it with 3 receivers without problem. Told the tech I want to upgrade to SWM16 when available for MRV. He said he would never install a SWM with R59 wiring present because it would fry (yes burn out) the wiring after a month or two. Is he correct??
