Coax and coax calculators

[Flameout]

I was trying to avoid having to ask yet another coax question here, but using the coax calculators that are out there really didn't help. None of them list the two types of cable that I have.

Both are 50' sections with professionally installed PL259 connectors (I wish they were N, but they aren't)

One is ABR Industries LLC-25400F RG-8/U 50 ohm Low loss High Flex Direct burial https://www.hamradio.com/detail.cfm?pid=H0-017172

and the other is Wireman CQ1000 LL400 50 ohm low loss https://thewireman.com/product/cq-rg8-low-loss-4xl-lmr400-equivalent/

Which would be better for GMRS? The antenna is a DB404 and using a coax calculator, what would be the equivalent to these, as none of the calculators show them

Your coax calculator doesn’t have RG8/u or LM400?

[Flameout]

No RG8/U but there is Times Microwave LMR 400 but the Wireman stuff I have looks and feels a lot different than the 25' section of LMR 400 that I have.

You don't even need a calculator for these two. Your second link shows loss at 450MHz (2.7dB), and little googling brings this page: https://abrind.com/coax-guide-2/?gclid=EAIaIQobChMIhor86fWt-gIVpT2tBh1P-gcyEAAYASAAEgLy4_D_BwE where loss for 25400 at 450MHz is 3.3dB. So, Wireman is better, but LLC-25400F is a direct burial.

Ok, thanks. I was thinking they were around that, per 100' but wasn't sure I was looking at the right info. The LLC-25400F will be MUCH easier to work with. That Wireman stuff is almost as bad as hardline
