My multi-two station, with third spotting station, is being rebuilt into new digs. I have a lot of 3-4 foot RG213 cables running between the amp, power meter, tuner and switch. I have heard there may
Hello Keith: Only using RG-400 double shield high isolation cables at K3LR https://www.dxengineering.com/parts/dxe-rg400r003 Handles 1500 watts in the HF bands no problem. 73 Tim K3LR --Original Mess
Keith: A couple very similar candidate cables are RG-400 and RG-303. RG-400 is double shielded while 303 is single. They're good as interconnects because they have a small bend radius (about 1"). RG
I third the sugjestion of the RG400 small enough for all the switching in a more then one radio setup. The tight bend radius the small diameter make for a clean instlation that coupled with the doubl
The quality of a cable shield can have a strong effect on crosstalk, very important in a multi-transmitter environment. This characteristic of a cable shield is quantified as its Transfer Impedance -
Thanks for the info. Looks like RG400 is an excellent choice. 73, Keith NM5G The quality of a cable shield can have a strong effect on crosstalk, very important in a multi-transmitter environment. Th
I just bought 10 feet of RG-400U (supposedly Harbour Industries) through E-bay for $13. Belatedly, I learned it was coming from China. It's now here, but I don't think it is for real - it only has

Can you file a complaint with eBay and get your $$ back? Sounds like the "RG400" is actually not-as-advertised. 73, ron w3wn I just bought 10 feet of RG-400U (supposedly Harbour Industries) through E

Pete It would be helpful to know who the vendor is that you bought the bad cable from; so we don't make the same mistake. A link would do the trick.73,Gary K9GS -- Original message --From: N4ZR <n4zr
This is an interesting post since I just made a RG400 jumper last night. It was made with coax also purchased on eBay more than a year ago however mine is clearly marked with the manufacture's name -
Oops. I did some more dissecting on the cable, and I'm wrong about the shielding. That leaves only the absence of printing - this is advertised as Harbour Industries RG-400 - and its stiffness. Thi

Pete, Checked some RG142 vs RG400. With a hand squeeze test it is easier to flex the RG400. Not scientific but you can feel the difference. My RG400 is marked "M17/128 RG400 MIL DTL 17 27478 HARBOUR

Did some more checking on eBay for RG179. Besides selling some unmarked cable as "Harbor", there are listings that show Harbour Industries horizontal vs vertical printing on the coax. All my Harbour
The cable youre describing sounds more like RG-142 than RG-400. They look similar. RG-142 has a solid beryllium copper center conductor that is prone to fracture if flexed repeatedly. tnx Mike / W5JR

Both for re-wiring my station and for my project on the new Choke Cookbook, I've purchased roughly 200 ft of RG400, all printed with the label of Harbour Industries. It is relatively stiff, as are ot
Hi Pete, I can easily wrap my Times Microwave RG-400 around my finger. But the improved shielding effectiveness of double shielded coaxial cables such as RG-400 and RG-214 doesn't provide a useful pe
