Hi All,
Please use this thread to confirm your attendance at our annual holiday party and how many. The Ixtapa Redmond Ridge reservation is for 6 p.m. Ordering is off the menu, and separate checks, no pre-pay. I already have Kathy and Rowland and Lindy and Chuck confirmed. Thank you very much.

I'll look when I'm back home. I may have 100' of excess.

Worth noting that while DXE does occasionally stock LMR400 (a product by Times Microwave), most of what we buy is "DX-400."  They are both great product, but definitely differ.  The plastic used on the outer jacket is more plasticky on the DX Engineering stuff, slightly rubbery on the Times stuff.

UltraFlex is also a Times Microwave brand, but others have produced equivalents.  I use DX-400 Flex or whatever they call it (braided center conductor), as the real deal is even _more_ expensive.

I've also had great luck with Shireen's knock-off "400."  When I was last looking, it was hard to find in quantities less than a full spool, but it might be a good option for a group buy.

As others have said, .2dB/100' isn't a huge deal for most uses.  Longer runs, consider coax to a 1:9 transformer then 450 ohm window line to a 9:1 on the other end; lower loss than LMR400 and it's cheaper and less of a PITA than hard line. DXE manufacturers a pair of these. They're nearly impossible to find on the site - I'll find the model number, if anyone is interested.

K7ADD/AM somewhere over Canada

Good question.  I had thought it was from the end of the feedline cable but if it’s a pl-259 magmount then it could be from the antenna mount point.

Which is it, Rowland?

3 for dx engineering. Also agree with ultraflex. I vote for the pl-259 connectors. They're supposed to be good up to 300mhz iirc. I only use N for my scanners above uhf.

If you can spare a few bucks I'd get the dx engineering RG213u for hf. The dialectric doesn't soak up water and you can direct bury it.

I’ve had good luck ordering coax (both LMR-400 and RG8X) from DX Engineering.

It might be time to consider another group coax buy from DX Engineering…

Thanks Jim,

There’s a very high probability that I’m not designing my HF antenna cox run correctly. I was thinking of running LM 400 right from the back of my rig in my shack (home office) to the external tuner and ladder line for an open wire dipole strung up in some trees.  Thanks for the input. I’ll definitely get the ultra flex and connectors.

Hi Howard,

That's a lot of coax!  Going to be expensive...

Make sure you get the Ultra Flex version of LMR400.  Typically P/N is LMR400U or LMR400uf.  You will be glad you did.  Much easier to work with.

You are going to want N Connectors installed on the cable. 

ABR Industries makes really good cable.  You can get that at HRO (Ham Radio Outlet)
