Hi John,<br>
<br>
You have roof access to this condo? The landlord lets you mount
stuff up there? If so, are you able to take a zoomed photo of the
Westin building from there? (not the round hotel towers, but the
square office building) I'm curious which floor(s) you can see.<br>

Subject: [HamWAN PSDR] Request for onsite HamWan
signal strength test<br>
Hello folks, I had a person (whose name I can’t recall
unfortunately) come out to my condo building a short
time ago and take signal strength reading to various
HamWAN sites in the area (gold/beacon/and haystack).
But my original plans for the antenna location have
changed and I really need someone with a portable
system to visit again and take some readings from a
new location on my condo roof.<br>
<br>
I live at 2801 1st Ave, in the Belltown neighborhood
of Seattle.<br>
<br>
I could also use a materials inventory list or an
Elmer kind enough to stop by and help me figure it up.<br>
<br>
I will compensate for someone’s time if that would
help get someone here.<br>
<br>
Thank you.<br>
John WA7UAR<br>

John,<br>
<br>
If you still have line of sight from the new location,
the signal strength should be virtually identical to
what you had before (given the same type of antenna).
The real question is if you will have line of sight to
at least one of those locations (that's all you want
to shoot to). So, standing at your new antenna
location, look and see if you can actually see
(visual) each of those destinations. Of course, clouds
and weather may prevent you from actually seeing it,
but you should be able to look in that direction to
determine if there is anything blocking.<br>
<br>
As to actual signal strength, that will depend on what
antenna you use. You have several choices from a 30dbi
dish to a 19dbi panel. The higher the dbi number, the
more gain, hence more signal strength, you will have.<br>
<br>
What type of antenna did the person who came out
before use? Was it an actual dish (round or oblong),
was it a flat panel roughly 12" square, or was it a
flat panel roughly 4" square? The smaller should work
well for Beacon. The larger 12" flat panel should work
for Gold and maybe for Haystack. A 30dbi dish will
absolutely work for Haystack.<br>
<br>
Attached is a screen capture of Google Earth with
bearing lines to each of the following from the center
of your roof, going clockwise - Haystack, Capitol
Park, Beacon, Gold. From where you plan (are able to)
mount your dish, which of those is the best to use?<br>
<br>
If you got a decent signal from a previous test, I
have no doubt you can get a good signal from another
test. The real question is exactly where will you
mount your antenna, what will it be mounted to (how
secure), how much clearance is there around it, and
what (if anything) is in the way of one of the paths
on the attached screen captures?<br>
<br>
Shooting to Beacon is probably your best option if you
have a clear path. That is close by, so much stronger
signal (and smaller antenna needed), plus it has paths
to Baldi, Gold and Haystack - so lots of redundancy.
Shooting to Gold would be my second choice. Shooting
to Haystack would be my third choice, and shooting to
Capitol Park my fourth choice. The last two have less
reliability than the first two (longer shot to
Haystack, Capitol Park shoots to Haystack so is just
one more thing in the middle of going to Haystack).<br>
<br>
For Beacon, the two buildings directly to your south
might be the obstacles you have to avoid. If you can
get past/over them, you should have no problem. One
of the small 4" square panels mounted on top of a pole
as high as you can get it might serve your purpose.<br>
<br>
I'm happy to stop by some day with a 12" and 4" panel
to test with. I've got a bigger dish, but it is
cumbersome and hard to move. If you'll cover the cost
of parking, I'll make the trip.<br>
