Comms bug out bag gear

I offer this resource:

And I make a suggestion to set some sort of reminder or alarm to check the status of your batteries on a regular schedule. A ready bag is really a good idea but it's not a make and forget thing when batteries get involved. REI has so many 'beaners that your likely to get a shiny-hemorrhage in your brain should you go look :)

Hi all! Putting together a comms bug out out bag and looking for some direction. I've already secured a Fara-J antenna and throw line. What coax would you recommend that is lightweight yet good quality? Looking for about 50 ft. Also any recommendations for sbiners. 

Thank you in advance! 

I would recommend using RG-8X cable. It has far less loss than the typical RG-58 type and just slightly larger in diameter. You can use larger coax like LMR-400, less loss, but its much more bulky and heavy. But for a portable application I would assume you would like something small, light and easy to carry.

All my portable radios I typically use BNC connectors. Those don't cause SWR problems and are low loss when using quality types. You can find adapters from just about any connector type to BNC. I have BNC adapters for all of my radios.

I would use the minimum length of coax to get the job done. The link below is for a 25 foot RG-8X cable with male BNC connectors on the end. If you really need 50 feet then use two with a BNC barrel adapter. Otherwise the 25 foot one would likely be more than enough.

I use a portable mast system with about 25 to 30 feet of RG-58 cable. The higher loss on the cable helps to keep the SWR on the antenna down below 2:1. That's a trade off I made and I had the cable already. If a find a good buy on a RG-8X jumper cable I'll swap out the RG-58.
