The question is, can you get RG-316? Same size as 174 but higher power handling capacity and tougher jacket.

Re: [Elecraft] BNC jumpers? (Thanks)
I think RG142 is closer. Specifying that doubles the price, depending on length. Worth it if you need the power handling and flexibility.

Re: [Elecraft] BNC jumpers? (Thanks)
I generally would want UHF connectors, but some BNC. Neither of the two houses I mentioned show UHF connectors at all. They're generally targeting the commercial world and seem to be at home with BNC, TNC, N, SMA and some of the specialty Motorola connectors. On the other hand, there are some places that specialize in the amateur world - Cable Experts (www.cablexperts.com), ABR Industries (www.abrind.com) - who don't seem to have BNC to BNC but look to be heavily into UHF and N cables in .240 inch (RG8X size), .405 inch (RG-213, LMR-400 size), and .60 inch (LMR-600) cables. The LMR/CNT cables are double shielded (braid over foil) where the RG8X and RG-213 cables are single (95%) shield. Cable Experts also shows RG-142U (Teflon, .195 inch) cables ... 73, ...

RG142 has a copperweld center conductor which isn't very flexible RG400 is similar but has a stranded center conductor and is more flexible (but also expensive). 73, Bob N7XY On Apr 8, 2012, at 11:24 AM, David Cutter wrote: I think RG142 is closer.

The steel component of copperweld makes it lossier than solid or stranded copper below about 10 MHz. You can see this in graphs of loss vs frequency for coax with CCS center conductor. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] BNC jumpers? (Thanks)
You can frequently find RG400 jumpers for sale on eBay, with useful lengths, even if you have to cut off the connectors already on them. They sometimes have one or more BNC connectors already on the cable. RG400 is still made new and is rated for the kinds of sharp bends that are found in aircraft wiring harnesses. This is really good stuff that will last a lifetime. Rated at many times ham radio QRO power level. It's good for SHORT runs in a station, very flexible and looks good bundled up. It's the same outside diameter as RG58 and uses the UG175 adapter as a good fit adapter to put a PL259 on the end(s). What I like the most about it, is in soldering connectors, you CAN'T MELT it. You can strip a bit of the outside jacket and sweat (solder) the shield to copper strap without harming it in any way, for excellent grounding and bonding of stuff running around the station. I've only ever been able to do that with teflon coax. Once you get to know all RG400's advantages, it kind of grows on you. 73, Guy On Sun, Apr 8, 2012 at 8:10 PM, Bob Nielsen n...@clearwire.net wrote: RG142 has a copperweld center conductor which isn't very flexible RG400 is similar but has a stranded center conductor and is more flexible (but also expensive). 73, Bob N7XY On Apr 8, 2012, at 11:24 AM, David Cutter wrote: I think RG142 is closer.
