Excellent Product
Excellent quality. Item is a little stiff and may cause problems if you need to make tight bends, but I should have expected that due to it being LMR-400, but with a little bit of re-designing in my project, it worked perfect. The coax is marked as Times Microwave, so it's the good stuff, not the cheap knock off. The connections feel tight and solid. I am using this inside a 12"x12"x4" NEMA4 box connecting a 1090MHZ filter to a bulkhead mounted polyphaser for an ADS-B set up on my tower.

Top Quality that you will not regret
This looks like top quality cable that is made in the USA. Excellent for permanent outdoor installations that you want to avoid maintenance on. The cable is stiff and does not flex easily, but will flex with effort. Connector ends are well reinforced. Remember to water proof your outdoor connection.

I use w/my Alinco 902-927MHz HT & Comet base antenna.
MPD Digital Times Microwave LMR-400 Coaxial Antenna Cable Line with N Male & Straight SMA Male Connectors, 15': I use it to connect a Comet vertical base antenna to my Alinco DJ-G29 HT on the 902-927MHz band during ARRL V/UHF contests. Quality connectors, no adapters needed. The cable is necessarily rigid. So, if twisted the wrong way, my HT can be yanked off the table. The setup DOES work. I've made a few almost 100 mile hilltop to hilltop contacts on 902 FM, 2-watts. The cable is recommended for this niche ham specialty.

Very high quality
If your not sure of the angle it'll be connecting to the router (mofi4500) then I would buy two flexible adapters, not from them but you can, so your not trying to bend this wire. The Ultra-Flex style these guys sell is what I should've bought, that way it's adaptable to the situation.

MPD cables last and are durable, I have proof
About 1.5 years ago I got 3 MPD cables and one cheaper competitor cable. Welp, after a week of systematically troubleshooting my equipment, I deduced a recent radio signal decrease came from failure of the cheaper competitor cable (Proxicast). I recently moved and slightly bent that half-failed cable no more or less than I moved and slightly bent the MPD cables which continued to work great after the adjustment. All three MPD cables have lasted and performed well so far. My point is that MPD cables are worth paying more for. Just pay a bit more once to avoid buying again, and the headache of cable/mast runs from cheaper options you will have to replace next year!

Improper assembly yields -10B loss
Retired EE. I got a pair of these for a MIMO antenna, and found that one was consistently loosing one bar of signal strength or more. I put in an old LMR 200 cable and all was well. One N male end was loose- inproper crimps on both the crimp sleeve and NO crimp on the pin, slipped right off. I found a similar no crimp pin on one SMA end also. I was able to easily pull it apart and reassemble, solder the pin and replace the crimp ring with a new one. I sure won't be buying cables premade from this alleged US assembler- they have serious training/QC problem. They don't seem to understand that SMA and N crimp connectors don't have a collet to tighten the male pin on the center wire like the clamp style do.

awesome cable! Of course LMR400 is great cable
Wow, awesome cable! Of course LMR400 is great cable, but I was really impressed with the high quality job done on the connectors. Awesome job complete with heat shrink tubing to seal them up. I'll definitely be ordering from them again in the future. Plus they offer just about any cable you can imagine and I'm sure they'd custom make anything you could dream up.
