newzhack Posted December 26, 2019 Report Share Posted December 26, 2019 I hate reception problems and I am about to purchase a new PSC multi for my two omni directional paddles. Question, what cable are most using to route the outputs from the distribution box. regards from Oklahoma Quote Link to comment Share on other sites More sharing options...
drpro Posted December 26, 2019 Report Share Posted December 26, 2019 I use RG-316. It's double shielded. This does make it stiffer. Also fairly low loss for its size. Quote Link to comment Share on other sites More sharing options...
henrimic Posted December 26, 2019 Report Share Posted December 26, 2019 I use these 250 mm sma to sma cable between the receivers and the PSC https://www.te.com/usa-en/product-1337812-1.html Between the PSC and the antennas, I use RG58 but not more than 10 meters. If I need longer, I'll use Sommer RG-213 Quote Link to comment Share on other sites More sharing options...
Derek H Posted December 26, 2019 Report Share Posted December 26, 2019 Newzhack, what kind of setup is this for? Over the shoulder bag rig or a cart? And you’re wondering about patch cables between the distro and the individual receivers or between the antennas and the distro? In a bag I think most people are using RG174 which is thin and flexible and lossy but at 2’ or less should be negligible. On a cart the size and flexibility is less important so use whatever you like. RG8x (better than 58) would be my choice for long runs and maybe short runs too. LMR-240-UL is the same size as RG8x but with better specs since it has a foil shield in addition to the braid. But it’s a bit less flexible.

drpro Posted December 27, 2019 Report Share Posted December 27, 2019 or just get some LDF50. Loss ar 500mHz is about 5db per 100meters power handling is 1.5kw at that frequency. You would be the only bag op with hardline!! Quote Link to comment Share on other sites More sharing options...

Never mind, just looked it up. 1/2” thick with corrugated copper shield... that’d be a nightmare on set if you ask me. Isn’t that kind of cable meant to be installed once and never touch it again? I think RG8x is the right thing for film set work since it’s the same diameter as heavy mic cable ~1/4”, flexible enough to lay mostly flat and having a stranded conductor and no foil it rolls up nice again and again.

drpro Posted December 27, 2019 Report Share Posted December 27, 2019 It is I was just kidding. Definitely would make sense in a permanent install, studio, theater, etc. For a bag smaller/flexible/lighter makes perfect sense. With the RF in and around my bag I want something with 100% shielding. RG316 along with some similar size coax offers. For a cart based antenna system I would definitely choose another cable, though still double shielded. Quote Link to comment Share on other sites More sharing options...
Derek H Posted December 27, 2019 Report Share Posted December 27, 2019 Gotcha, was wondering if you were kidding! I agree on the double shield. I’m planning to re-wire my humble cart setup with LMR-240 ultra flex. As far as I can tell it’s pretty much identical to 8x but with the addition of a foil shield bonded to the dielectric.

drpro Posted December 27, 2019 Report Share Posted December 27, 2019 I use LMR-240 for some of my ham radio gear. Excellent cable, though removing the bonded foil shield has its moments!! Quote Link to comment Share on other sites More sharing options...
Derek H Posted December 27, 2019 Report Share Posted December 27, 2019 Yeah I was wondering about that. Is it even necessary to do so? Quote Link to comment Share on other sites More sharing options...
resoNate3973 Posted April 3, 2020 Report Share Posted April 3, 2020 Slightly unrelated question, but still related to PSC Multi, What are y'alls opinions on using the 470-~800 Mhz version versus the 470-618, 940 version? I'm concerned about overloading the multi with cell signals in the higher frequency bands that aren't filtered out. I know I can use filters, and my antennas will cut off around 700mhz, but I'm just curious in general would that be an issue? PSC seems to think it shouldn't be, but just wanted to see if anyone has run into an issue with this and do you think it is better to go with the new dual band version? (I like the full range version in case I need to shoot in Europe (obvs it will be a while with the current state of things) ) Thanks!
