LuisT Posted January 21, 2021 Report Share Posted January 21, 2021 Hello everybody! What are you using as a coax cables for long runs? It will be used with a Wisycom LFA and BSRF AS122 distro. I am searching something flexible so i can use it on a drum roll. My sound shop is using Aircell7 usually and i heard about Lmr240Uf. (Slightly more loss at 500mhz but thinner). Thoughts?

Derek H Posted January 21, 2021 Report Share Posted January 21, 2021 Wasn’t this already posted? RG8X would be my choice for a long run assuming you’re using a powered antenna. Quote Link to comment Share on other sites More sharing options...
LarryF Posted January 21, 2021 Report Share Posted January 21, 2021 Cable loss is inversely proportional to cable diameter. RG8X is a smallish cable (.250" similar to RG-58) and will be relatively high loss over long runs. Don't confuse RG-8X with RG-8, which is a .400" cable with less loss over long runs. There are other .400" inch cables that are more flexible and have foamed dielectrics for a little less loss, emphasis on little. Google a cable loss table and figure out what kind of losses you can stand and make your choice. There rarely is a free lunch at the RF table.

Philip Perkins Posted January 21, 2021 Report Share Posted January 21, 2021 RG8. Worked great, but affordable=stiff, not a great thing for days with a lot of moving around. Quote Link to comment Share on other sites More sharing options...
Derek H Posted January 21, 2021 Report Share Posted January 21, 2021 That’s why my vote is for RG8X. Anything thicker is a bear to wrangle and arguably unsafe to lay down on a busy set unless you tape the crap out of it. You can deploy RG8x quickly and a good amplified antenna will overcome the loss for 120+ feet and it will work. If you need a lot more length than that then I would look for different advice. Maybe optical conversion? Don’t know? Quote Link to comment Share on other sites More sharing options...
LarryF Posted January 21, 2021 Report Share Posted January 21, 2021 Hi Derek, Now that you added amplification, I agree totally. Just make sure it is a high overload amplifier, i.e., pretty high current (power). It's not even necessary to use RG-8X (though it is the best of the .250" cables). Good ol' RG-58 will work fine, if you balance the amp gain and cable loss. Best Regards, Larry Fisher p.s. If the amp manufacturer or amplified antenna manufacturer doesn't spec third order intermod values, it's probably a poor choice. Quote Link to comment Share on other sites More sharing options...
LuisT Posted January 22, 2021 Author Report Share Posted January 22, 2021 Hi ! thanks for the answers. I found on the forum but didn't found it. Is RG8X more flexible than LMR240 UF? Thanks Also what is the difference beetween RG8 and RG8X? Quote Link to comment Share on other sites More sharing options...
Johnny Karlsson Posted January 22, 2021 Report Share Posted January 22, 2021 Here’s a calculator that allows you to enter different types of coax, in addition to cable length, frequency etc. and see how much insertion loss you’re looking at: https://www.timesmicrowave.com/calculator/?Product=RG-8X&RunLength=100&Frequency=550 Now, that’s of course not going to tell you how stiff or supple a particular cable might be, but at least it will give you some helpful info to work with.

Not a huge difference but the LMR240UF has a bonded foil shield in addition to the braid that makes it a little stiffer. Otherwise it’s very similar. Uses the same connectors. It’s a bit trickier to terminate because of the foil shield you kind of have to trim it back a little bit and it’s glued tight to the dielectric.

RG-8X is .250" in diameter and RG8 is .400" diameter and half the loss per length. Best Regards, Larry Fisher Quote Link to comment Share on other sites More sharing options...
drpro Posted January 23, 2021 Report Share Posted January 23, 2021 When performance matters LDF-5. About .9db per 100' of loss at most wireless frequencies. Not light, doesn't roll very well, but will impress the client. Have several rolls in the garage. Quote Link to comment Share on other sites More sharing options...

lazajamsonic Posted February 23, 2021 Report Share Posted February 23, 2021 Curious if anyone can recommend a good source for a coax cable wind up ‘reel’, hand crank style. Have searched all over and haven’t found a winner yet. Worked with a mixer who has had a couple of these, 2-pair loomed coax reels at 75’~ length, from Silent Sound in Toronto. They are too busy to build one for me lately so I want to try and get it built elsewhere/ DIY! This thread is super helpful to decide what cable to use, thanks @Johnny Karlssonfor that link!

Thanks Paul, yes I could have been clearer in my request above - I will elaborate! This link shows the specific style I am after... (except not an AC cord, obviously). An enclosed retractable reel, but with a plain centre section where I can install two 'surface mount' BNC connections. Where does one buy such a thing? https://www.amazon.ca/Woods-2801-Power-Extension-25-Foot/dp/B000GAS3A8?ref_=Oct_s9_apbd_omwf_hd_bw_bAbXRAR&pf_rd_r=1MM3D6YBA3JAPB8TWBV8&pf_rd_p=c424f636-186f-52e9-a942-15f2f915a80f&pf_rd_s=merchandised-search-10&pf_rd_t=BROWSE&pf_rd_i=9716022011 Quote Link to comment Share on other sites More sharing options...

Markertek. I have a 100' coax(BNC)/dual XLR reel with panel mounted connectors on the reel and a 200' ethernet reel with panel mounted jack. They are well made, lightweight and reasonably priced. Those were actually pre-made, but they do custom, as well, if they don't already have what you need. A quick look on their site(not as user friendly/searchable as it used to be) I ran across a single and triple coax reel, but not a double. Not saying there isn't one or they won't make it, but just didn't see one in the quick glance I took. Quote Link to comment Share on other sites More sharing options...

The LMR240 is nice, is a bit thicker than the RG58 (6,1mm instead 5,5mm of the RG58), up to 22m for a 5dB (550MHz), but is a bit stifther than the RG58 Quote Link to comment Share on other sites More sharing options...
