[Repeater-Builder] Re: Double Shielded Cable
Ok now my next question is which is better the RG 142 or the Super flex? This will be used between the Duplexer and tx rx? Thanks KC8FWD

Re: [Repeater-Builder] Re: Double Shielded Cable
RG-400 is a better choice than RG-142. RG-400 has a stranded center conductor and will take repeated bending better than the RG-142 with its solid center conductor. Best choice between RG-400 and Superflex will be mostly length (loss) related.

Re: [Repeater-Builder] Re: Double Shielded Cable
RG400 would be a better choice than RG142 as someone else pointed out. If you are going to make your own cables, you then have to decide what cable you are going to be more comfortable putting connectors on. My opinion is that the cable loss for a short jumper of RG400 vs Superflex is negligible, but a poorly installed connector will cause a big difference. 73, Joe, K1ike kc8fwd wrote: Ok now my next question is which is better the RG 142 or the Super flex?

I use RG223 for my TX RX jumpers unless I need more than 2-3 ft. it's for UHF, then I go to RG214. RG223 is a bit more flexible than RG400. Bob NO6B

Mike, My personal preference is Andrew FSJ1-50 1/4 superflex. To save on connectors you can use silver/teflon PL-259 or the new style silver N connectors that assemble like a PL-259 with a silver UG-176 reducer on this cable. Just drill a 1/8 hole through the reducer to solder to the copper jacket. Assemble the rest of the connector as normal. I have had very good results on both VHF and UHF. Often times I cna pick up a few DB extra isolation which really helps with desense on VHF where we only have 600 KHz of spacing and need all the help we can get.
