In order to use a 110v extension cord from my router it would need to go through an outside wall. through the crawlspace and through an inside wall. That would be an electrical code violation and not something I want to risk doing. It's possible to find an electrical circuit in the the crawlspace to tap into, install a junction box and install an outdoor rated outlet on the outside wall below the modem. That's a lot more work than just running another low voltage cable.

The battery is an interesting idea. I'll probably just run another cat6 cable since I already have everything except the POE splitter.

Of course you do what's best in your case, those were merely some suggestions.;)
I might try the battery thingy myself, since it also provides a power failure backup at the same time.

I looked at them a while back, and they were all low level CAT rated, verses buying the newer Sierra MC series modems which supported the latest LTE releases.
The HAT version doesnt have a modem embedded like the shields previously. Its pretty new-ish.

oh that's pretty slick, but a USB enclosure is still cheaper.

Granted if you're tight on space, that's not a bad idea.

Wow-we-Wow, I like that! Have some older pies laying around but this renews my interest, thanks for sharing the link!

Hi, I’m looking into doing a similar setup as yours and I’m wondering what the high pass filter does?

It filters out any radio frequency below 600mhz so the modem doesn't see it at all. I did this originally to try to help the modem from being overloaded by strong nearby signals below that frequency.

That being said, it's not necessary for the average user, unless you live like within a mile or less of a nearby AM or FM broadcast tower. It turned out being very useful for me because I'm also into ham radio and have very strong nearby antennas that transmit below 600mhz.

Swwifty,

That's cool! Im curious though, how much loss does each one add to the cable runs, specifically?

Might be worth looking into for many more people if its negligible.

I can't remember exactly but I'd suspect its .1 - .2 db. not very much. It wasn't a cheap filter.

I'm getting close to replicating your setup - but can't run my Pi over POE - I only get a flashing red light. Can someone provide guidance on where I went wrong?

I've purchased:

https://ltefix.com/shop/power-adapter/p ... mm-jumper/

and

https://www.amazon.com/gp/product/B019C ... UTF8&psc=1

To power:
https://www.amazon.com/gp/product/B07BC ... UTF8&psc=1

If I use the power supply that came with the Pi, all good.

Thanks in advance for your help!

EDIT: I believe I found the issue: Need 2.5 Amps. (only getting 1.5) Can anyone verify?

Your gunna smoke you rpi with that.

The poe injector outputs 48VDC power, there's nothing there to step it down to 5V.

Lemme dig up a link for you.
