see if you can spot the radome.

Sure. Badger Mtn radio facility.
Can't link to it on DLR pages because he's
got the URL's cloaked.

Bald Mtn. The dish with radome on what I
think is the NE corner of the scaffolding.

The Lincoln County phone dish on Mt Irish, pointed
at Rachel.

The Flat Top facility. Which as I understand
is no longer there, was pointed at Mt Irish.

All of those have radomes that look exactly like
what I'm seeing in that area west of Papoose.

I'm not sure what that antenna might be pointing at.
Drawing a line 270 to the map doesn't seem to take
me to anywhere significant. Remember they use a lot
of reflectors here and there around the ranges. So
if that is a dish, pointing 270, it might hit a reflector
angled to CP1 or any of a gazillion other places.

They used to test UAVs in that valley between papoose and
GS700. Perhaps that antenna/facility, whatever it is,
has (had) to do with that.

Maybe it's so the grays can watch ESPN.

You were the "OPERATION" game voice?
Yes. Take out wrenched ankle.

tho some  flat panel arrays are used for shorter distances ( couple
of miles or less )  many are capable of large distances and several
types of  dishes are  commonly used for the longer local hauls  for
wifi  nets.

 I haven't looked at  the  cords you've  mentioned but I suspect you
aren't taking into consideration the extensive localized  wifi nets
which have  a  bunch of  smallish  and  larger  dishes  sprinkled
everywhere .

if they don't seem to be pointing at anything  obvious , then  look
a little closer to home  !

many nodes  of the wifi nets  can be a surprisingly large distance ,
with the higher power units having  unsuspected abilities.

take a look at my own personal phun toy , along these lines , which  I
posted on  alt.binaries.radio-scanner .  this setup can have  an  ERP
of nearly 15 watts  if I want it to  ( depending upon what I use in
the black bag and where I'm powering it up from ) .  even at it's
least powerful configuration powered straight from a laptop it has a
ERP of  4 watts ... +37db gain.  these use the USB port and have the
wifi card and power amp mounted  directly to the radiating element ,
inside the antenna ( to eliminate line loss and obtain maximum
efficiency ) .
( and yes the antenna in the photo has been pixel edited ,  before
someone goes off about the picture !  )

  a new frontier of interesting , generally overlooked ,  information
is  the digital wifi type of  signal sleuthing ....... right up there
with having a FM scanner, opto R-10  and  other , more traditional,
types of tech toys !   with the right vantage point , signal paths of
30+  miles  are easy to achieve !   the highly  directional
characteristics of high gain flat panel arrays  lend themselves to
accurately pinpointing the network  nodes  or active digipeaters.
that  and make you difficult to locate in return , if you aren't
directly pointed at the ...........

in some places there might even be the case of discovery of  totally
unsuspected  wifi net connections from locations that you'd never
think  were involved or related to interesting activities.  this from
high gain antennas completely camouflaged or hidden from view to the
general public !   just a thought , you never know !!!!!  yaya ayahah
ah a    I have not personally experienced this phenomenon but hear
tell  that using this type of equipment , at times,.  can bring a (
rather speedy )  highly undesirable HOT response from the choppers.
didn't  happened to me  tho   ..  not yet .

( take a moment to carefully consider  what kinds of equipment are
using and located as nodes on the many wifi nets !!  it's nothing
much to do directly  with  personal computers or building to building
data  conex ! )

k

p.s. ....... take this toy down into town and you can get all the
( phun )  free anonymous  high speed internet action you can use.

Nellis AFB has wifi. Rather powerful. I was able to sniff it with just
a biquad.

some of those military wlans appear to have transmitters in the
50 watt plus ranges.    blatantly  parking at the  gas station
( nellis ) or near  NTS with a flat panel tripod on top of your car
and hunched over the laptop is NOT a good idea tho !!!
yay ay ahah ah ah a

it would probably be better if I used the  term  WLAN  instead of wifi
( wifi  conjuring up a slightly different thought than I wanted  it
to  )

do you know  wharze  the  " dish "  in  your secam.jpg  is pointing ?

the stuff below works OK ..... but  factory pruned and tuned stuff  (
from Canada ebay where the power limits are higher than the USA  ), if
you can afford it , works a lot better ! it's not all that expensive
and lots of it is available used / surplus.

of course you don't need anything this big  h ahaha  but bigger is
usually better  !http://www.blogcadre.com/blog/jason_striegel/125_mile_wifi_connection...http://www.unwiredadventures.com/unwire/2005/12/defcon_wifi_sho.html

it's also good to know that all wireless cards aren't created equal.
some  built in and / or  pcmcia wireless cards are WAY better than
others in some metro environments .
 in a side by side shootout ,  while using a  9 db omni vertical
magnetic antenna  I've had some machines and / or cards  show as few
as 4 to  7  active APs .... while others in the same setup environment
showing as many as 39 different active APs. a large difference in
abilities.  basically the newer laptops ( say made by Dell , for
example )  have vastly improved range performance as compared to
laptops made only 4 years ago .   brands such Buffalo and Atheros
having  cards / chips  with surprising range and ack capabilities.

in Vegas , for example ..... in  the north side /  NW part ,
it's not unusual to see  over 130 active APs in a 5 block length
drive with one out of  every   7 or 8 being unsecured .  you can see
double or triple that in parts of town but not as many open to the
public  ...........  on the strip,  for instance !    lots of public
APs in Vegas  tho ! ...... lots .......

fun stuff ...........

I'm not sure which secam.jpg images, but most dishes point to Bald
Mountain. It is line of sight to almost everywhere. Just try to use
the er um facilities and get out of view of Baldie.

Note those people putting usb dongles in front of dishes really aren't
getting the full effect of the dish. There is a fine art of dish
"illumination".  A helix is best because you can control the beam
width. There are papers on line about how to do this.
