[HamWAN PSDR] Advice for parts for a portable setup

I am planning on setting up a portable unit myself, and just awaiting
re-stock of the antenna I plan to use so it can be ordered:

https://www.eurodk.com/en/products/mt-lhg/lhg-xl-hp5  This is a 9.5inch
diameter wind-resistant 27dbi gain dish with integrated
modem/router/firewall and is 24VDC PoE.  I have bought and installed the
smaller 6.75 inch 25dbi gain version of this same antenna at my home QTH
that is working well about 1.5mi away from the cell site.


I have another ARES team mate who purchased the small 5in square SXTsq 5HP
flat-panel 16dbi gain antenna for his portable station, which I think he's
mounting on a tripod.  His home QTH is a bit over 1mi from the cell site and
he needs to use it outdoors, but with no trees and clear LOS view it's
working well.  He's using this:
https://www.eurodk.com/en/products/mt-sxtsq/sxt-sq-5-hp   I worry that he'll
have some trouble with this smaller-gain antenna during field deployments at
a distance or during snowy/rainy weather.


For the portable use I have planned in emcomm field deployments and RV
traveling, I feel I need the most amount of gain I can get that is also
easily managed, transported, and setup/teardown.


I recommend that you use a dedicated laptop for HamWan with no valuable info
that you can afford to have exploited by an attacker, as I have experienced
twice now unauthorized router logon attacks after connected to the 44
network > half hour; since I'm a pro infosec guy, I have a pro-grade IDPS on
my local network that detects/blocks such attacks and alerts me, but most
people do not.so in addition to keeping everything patched, hardening your
MikoTik router config, hardening your laptop config and using good
anti-malware protection on it, you should think about what you can lose or
not lose and keep your HamWan dish powered off except when you are actively
using it.

Subject: [HamWAN PSDR] Advice for parts for a portable setup


Hello to the group!

I am on Bainbridge Island, and I am looking into a portable setup to
experiment with from different locations.

While there is a lot of useful gear info on the website and on this
listserv, I want to make sure that I don't end up getting something that
doesn't maximize data speeds or will be obsolete in a year.

I am looking for advice for a complete portable system. I can make use of a
power supply and tripod that I already have, although I'd be interested on
input on that, as well.

Thanks in advance for your help with this.
