Greetings!
I intend to build a 5 Ghz "Go Box" (somewhat) portable AREDN system that I can keep in a box in my car for emergency use,
mainly "mountaintopping". Any tips for recommended equipment? Is a higher gain antenna worth the increased size and investment costs?
Thanks!

Next, I'd recommend the Mikrotik hAP ac lite to plug in local devices, model RB952Ui-5ac2nD -- plugin laptop, ipcam, voip, etc. There are 3 LAN ports and can also do a wifi AP to connect in devices. Also, the hAP ac lite can pass though the POE power to the dish pointing to the mountain top. The POE passthough power is on the dtdlink connection between the nodes, and simplifies the cabling. Dtdlink is the connection between 2 co-locate nodes that routes mesh traffic.

HG XL HP5-US (USA) is factory locked for 5170-5250MHz and 5725-5835MHz frequencies. This lock can not be removed.
LHG XL HP5 (International) supports 5150MHz-5875MHz range (Specific frequency range can be limited by country regulations).
-RIchSuggestion: Ignore 'This lock can not be removed' and 'US' .vs. 'INTL'.
There are three:
25 dBm 24.5 dBi - RBLHG-5nD
28 dBm 24.5 dBi - RBLHG-5HPnD
28 dBm 27.0 dBi - RBLHG-5HPnD-XL

... a fun Go Kit. And her kit has saved our bacon more than once at AC100, B2V and more than a few exercises.
See the attached excerpt from her project poster.

Rich, like Joe mentioned Im using the MikroTik hAP ac lite, coupled with a Ubnt N switch for expanded (pass thru) poe lan ports. I added a Mikrotik LHG 5nD-LX for PtP link and a pi 3b+ with free PBX. This is all power by a lithium cell from Amazon https://www.amazon.com/gp/product/B07SWBS55F/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 which provides 24volt, 12volt, and 5 volt all in one nice package.

First, my AC Lite arrived a few days ago, and bringing up Aredn wasn't any more complicated than flashing the firmware in my MD-380.
You have answered my question of the day before I even had a chance to post it. I had spent the afternoon today studying voltage doublers, regulators, etc. to convert a 12 v battery to the 24 volts required for the AC Lite. Now none of that will be necessary.
Please allow me to ask a different question: When the AC Lite is fed with 24 volts via the DC input jack, will the POE output be at the same voltage as the input to the switch (Since it is passive), or should I use a PoE injector to power both the AC Lite, and the PoE out?
Eric, the docs claim that your Ubiquti N switch can handle up to 30 watts. How much current does a typical 5 Ghz setup use?
-Rich, KY6O
I have one and ISTR that there *is* a voltage drop when using POE-in on port #1 and POE-out on port #5 and it might be the same for wall-wart 24v-in as well, but so mush stuff runs just fine at a slight under-voltage when using short ethernet POE runs that it's never been a problem for me. Also the voltage-in specs on the hAPlite is a very wide range for the unit itself. - check the mfgr docs.

Guess my recollections were not correct as I can't find anywhere what I thought was a discussion of a voltage drop from POE-In to POE-out,
Here's what I did find from factory specs for MikroTik hAP @ https://mikrotik.com/product/RB951Ui-2nD :
"PoE in input Voltage 10-28 V"
"DC jack input Voltage 10-28 V"
"24V 0.8A power adapter"
"Unit provides PoE output function for port 5 - it can power other PoE capable devices with the same voltage as applied to the unit. Maximum load on the port is 500 mA."

Apologies,

OK you made me go measure it!
IN 24.10V
POE5 23.53V
0.6V voltage drop... makes sense since it's switchable.

Just a couple of days ago AB6BW and I did some testing - 12V converter to 24 volts to hAP input. POE passed through to port 5, feeding a Nanostation through about a hundred feet of cable, then POE pass-through through the Nanostation's Secondary port through another 120 feet of cable to a Powerbeam PBM 5 300. Using a POE tester the voltage at the Powerbeam was 22.5 volts. As an added point of reference the power consumption of the Powerbeam at that time was 3.7 watts. We didn't measure the Nanostation, but its power consumption would have been very similar.

My setup is similar to the pamphlet except I don't have the radio part as I don't own a mobile radio that small. I have the RigRunner setup in mine so I can use the USB ports to power a ZUMspot for DMR access. So related to that would DMR work on the AREDN network? So if we go with a 12V bus setup would that only work with 1 Ubiquity NSM5 or a NS-Loco M5?
Thanks,
