I have a number of filters and switches to wire up in my QRO station. I would like the necessary coax jumpers to be thinner (0.25" ?) and more flexible than, say, RG 213. They will be terminated by c

RG142 will handle the power but the center conductor is silver plate on copper clad solid steel (SCCS). RG400 is a more flexible choice as it has a stranded center, silver over copper, but given the
Or RG400 -- pretty similar, but center is silver coated copper stranded, two silver coated copper braid shields. RG142 center is silver coated copper coated steel solid, same shield. RG400 is a bit
This is exactly what I use. I purchased a 50' roll of RG400 for $100 on eBay and use it for HP jumpers and chokes. I think that it is better than RG142 for the reasons Jim mentioned. Amphenol connect

For those wanting to crimp connectors on RG400, I've been using these two types from RF Industries: PL-259: RFU-505-C1 Male N: RFN-1005-3C1 For soldering RG400 with a male PL-259, a UG reducer is nee
For jumpers in the shack what about RG-8X low loss with foil and braid shield that Davis RF lists? How does it compare to RG-400? The most power these jumpers would see is 100W. I use Buryflex from t
The key word here is QRO. RG-8X can handle up to 1000 watts, but suffers some heat loss at 1500 watts, mostly for 100 percent duty-cycle digital modes like RTTY. High dollar, double shielded skinny c
Keith, Tnx for info. Only interested n 160-6M here. I need to make up some jumpers. I have RG8X low loss cable already. Trying to find out if any reason to buy some RG400 instead. Most of the jumpers
Actually, the key word is SHIELDING, and shielding relates to 1) the resistance and 2) the uniformity/density of the shield. The TFE cables being discussed here have two very dense silver-coated copp
Since the subject is QRO jumpers, At 30MHz RG8X is rated at 350 watts (average) and RG400 is good for 2730 watts (average). The peak power level is higher so RG8X may still work however RG400 is the
Hello fellow DX travelers, FWIW my experience with RG-8X has taught me not to use it much. I tried building jumpers as well as buying some like you find for sale at ham fest. But it seemed that half
Agree with Terry, MPD has been a valuable source and delivers top quality at a reasonable price. They recently did some SMA cables for my ADS-B setup. Don W7WLL Hello fellow DX travelers, FWIW my exp
I see no mention of RG 303 and wonder if that's been discontinued. for jumpers I'd use 213. If you need a tighter bend radius I'd re-arrange or re-locate the connection points instead of using skinny
RG-303 is a good cable but not as good as RG-400 or RG-142 because it uses only a single shield. Also, I would still use RG-400 over RG-213 because it meets his desire for a small O.D. cable and bec
Not that I know of. But the center is silver-coated steel, which can increase loss at lower frequencies as compared to RG400, which is all silver-coated copper. 73, Jim K9YC _________________________
Gedas, Tnx for the info. Looking on eBay I see several listings for RG400 from China. I had heard Harbour Industries in VT makes a high quality cable. Not sure about the stiff from China., N2TK, Tony
