Hi Bob,
Good to hear from you again, we met at Valley Camp last year. It would be
very cool to interconnect the islands. The west coast of Bainbridge has a
good view of Seattle cell sites.
We can't get around line-of-sight. It is one big exercise in finding a LOS
path. Rob's request for site details would help drill down on specifics.
Seems like nobody from the Netops Team is available this Saturday morning.
A future zoom meeting would be much more interesting with specifics to
discuss. What questions do your members have?
An often overlooked concept behind HamWAN is that it is less about "the
Internet" and more about reliable communication between sites A and B that
you care about.
>From the San Juans, probably easiest to get LOS by shooting across the
water. Does anyone have access to a ridgeline or hilltop? Cell sites can
easily run with a solar panel and a battery, and can mount to a tree.
General information and hardware requirements are published at hamwan.org

Here is a recent post from Rob with plots of the Blyn/Coupeville coverage.

Blyn just came online, and is located at:
Latitude 48.006681 (48° 0' 24'' N)
Longitude -122.972646 (122° 58' 21'' W)
Any interested HAM could start by determining if you have line-of-sight to
this or other hamwan cell sites.
Use a high-gain dish to shoot long distances, and a 120 deg sector antenna
to re-broadcast the signal.
Bainbridge HAMs are also welcome of course. Kitsap ARS has expressed
interest too. John Hays K7VE suggested "Suquamish tower and perhaps at the
Casino up at Little Boston, they would have good visibility and coverage
for client nodes." in this thread about a Bill of Materials for a Cell Site.

Here are 2 emails I've sent before, copy and pasting in here for some
examples and more info. Please pardon borrowing from other conversations
without full context.
Example #1) KARS Field Day
Team, I just popped over to Mountain View Middle School to test the
connection to HamWAN @ Gold Mtn. Worked great! Brem SD Tech Director Mike
walked out to ask what's up, and explained that Field Day is usually in the
back field, whereas I was setup in the front parking lot.
On Friday, we'll need to identify a site location for my dish, with
line-of-sight to Gold Mtn. We could also colocate a regular old wifi
hotspot, fed from my dish. Probably best to have AC power, instead of
battery all day, but I can provide a bigger battery if necessary. Keep me
posted on timeline/plans for Friday setup.
2. Line-of-sight to Gold Mtn, easily identified by all the towers

3. Powering the device with a 12v battery, and a Mikrotik mUPS PoE
injector.

Zoomed view of Gold Towers, rough visual aim was sufficient.

Example #2)
Here is a smaller radio, connected to capitol park cell site. Shorter
range, less gain.
[image: 20181223_112817.jpg]
I buy this hardware from streakwave.com, reliable source for the ROW model
radios, and good prices.
MikroTik mANT30 parabolic dish antenna 5GHz 30dBi MTAD-5G-30D3
Dish also comes with a “precision alignment” mount.
*Radio Modem*
MikroTik RouterBOARD RB912UAG-5HPnD-OUT MIMO modem
You must order the ROW (rest of world) AKA International version *NOT* the
US version.
Amazon has them for $89.95 free Prime shipping but, you may not get the ROW
version.
*Optional*
If you are in a noisy environment, you may want to buy the optional. We use
this on towers.
MikroTik Sleeve30 Kit - Kit for mANT30 Parabolic Antenna
These are also options, integrated dish and radio, very nice, cheaper, less
dB gain on the dishes, so less range.
https://mikrotik.com/product/RBLHG-5nD
https://mikrotik.com/product/RBLHG-5HPnD
https://mikrotik.com/product/RBLHG-5HPnD-XL
even a flat panel like this:
https://mikrotik.com/product/RBSXTsq5nD
Any Mikrotik 5Ghz Dual Chain device will work. We can choose hardware based
on the range(gain), size, and cost.
I used a cheap speaker stand from amazon, I think a nicer stand would be
key to a reliable mobile setup.
As far as your internet connected repeater, where is that located? We need
Line of Site to an existing HamWAN cell site. We'd basically make the same
set of hardware choices to choose what to hang on a tower, or install
wherever your repeater is. If you have LOS to multiple HamWAN sites, we
could have 2 separate links.
IP addressing is 44/net public, dhcp. We can make static ip reservations by
cell site. Winlink is very easy, since it is a public IP address, there is
no port forwarding to configure, unless we choose to set our own firewall
rules. If there are multiple hosts (cpu, repeater) at a site, they can all
have individual public/static ip addresses, if that is desired.
